C. Steps for Implementing Grain Quality Delivery System

Step 1

Identify and contact a Grain Elevator/Buyer paying premiums for grain quality. Advise John Deere Field

Managers of any inquiries on their territory and set up a meeting to fully explain program and requirements.

Step 2

Grain Elevator/Buyer presents a program to show how Growers could earn premiums. They (Elevator/Buyer)

will also provide a list of growers who would be willing to participate in this program. (Suggestion: 25-30

growers is a good start so that the program will be easy to monitor and modify for this area.) The Grain

Elevator/Buyer will also designate an Account Champion at this time. The John Deere Field Team (TM,

TCSM and ADM) will then determine which John Deere Dealerships will participate according to the grower

list.

Step 3

John Deere Field Team contacts the targeted John Deere Dealerships to explain the program and determine

who will represent their Dealership. (Usually one Technician and the Service Manager) Dealership

Personnel chosen will be part of the Grain Quality Delivery Team responsible for inspecting, and certifying

combines, front end equipment and educating the Growers in the area of that given crop. The Grain Quality

Team and Account Champion are responsible for getting the equipment, materials and location for the

Grower’s Education Meeting. The Product Specialist should follow up on this.

Step 4

Product Specialist and Grain Quality Team meet to review and set up a common inspection checklist for the

equipment and price for the inspection. Product Specialist will then train the Grain Quality Team on the

combines and front-end equipment at the Buyer’s location.

Step 5

Grain Quality Team then delivers training to the Growers. Product Specialist, Field Team and Account

Champion assist as needed.

Step 6

Account Champion hosts a follow up meeting after harvest with the Grain Quality Team, Field Team and

Product Specialist. This meeting lets the group discuss how harvest went and if there will be the need to

change anything for the following year.

E. General Guidelines for Cleaning a Combine

Run the separator and unloading system in the field without taking in crop. Shut machine off and wait for

all moving parts to stop. Drop the trap doors (stone trap, tailings & clean grain elevator, grain tank sump

covers and clean grain supply auger drain covers). Clean off the top of feederhouse, cab, rear hood and

straw chopper or spreader; clean the ledges in the grain tank. Run the separator and unloading auger a

second time.

Remove all shields and open all remaining doors (inspection panels, feederhouse top covers, separator

covers, etc…). Remove chaffer and sieve elements. Remove bolts and open the clean grain and tailings

cross auger tubes. Open engine compartment and rotary screen door.

Clean the machine with an air hose working from the top down. After blowing out the grain tank blow off

the top of cab and between the cab and grain tank. Next blow out the engine compartment thoroughly

starting with the cooling package.

Continue with the air hose to the main body of the combine. Working from the top down and from the

front to the rear. Blow out the feederhouse and stone trap area. Moving reward to the threshing area and

on to the separator area.

After completely blowing down the entire machine clear the area of any bystanders start machine and run

the separator and unloading system to remove any seeds and debris still in machine.

After you have run machine for 1 to 2 minutes shut down and repeat steps above. Start in the grain tank

with a flat head screwdriver or pointed stick. Dig out any lodged grain and debris in and around the clean

grain elevator and corners of grain tank assembly. Use the high-pressure air after you have loosened all

areas of buildup.

Continue with the feederhouse using the same procedure digging out lodge grain and debris. Then blow

from the top down (through the top door towards the front of the feederhouse). Roll the feederhouse

conveyor chain over by hand and blow out again.

Clean the concave area while moving the concave through its range or blow it out in the lowered position

and raised position after dislodging material with a flat headed screwdriver or pointed stick.

Inspected the separator area and dig out any lodged grain and debris than blow out with the high-pressure

air. While blowing out the separator area stop periodically and roll separator over by hand to ensure all

areas are clean.

Blow out and around straw chopper/chaff spreader and straw spreader.

Using your high-pressure air blow out clean grain supply auger troughs, clean grain auger trough and

tailings auger trough.

Go back over machine inspecting areas and use a vacuum (hand held dust buster or small canister with

long flex tube) and clean any grain or debris left behind.

Install sieve and chaffer, all doors and covers removed for cleaning and install all safety and mud shields.

*This information is also available in the combine operator’s manual.

A. Reel Adjustments ( 900 Series Platforms)1. Setting Reel Safety Stops

1. Sound horn, start combine engine, and raise reelall the way. Stop the engine and remove key.

2. Unhook stop (A) from clip to set stop on cylinderpiston rod.

3. The stop must be snapped over cylinder rod withlock (B).

4. Set safety stop on other end.

2. Fore/aft Manual Adjusting Slat Reel

NOTE: The reel is easier to move if arms are level.

1. Raise reel and lower safety stops (A) on bothsides.

2. Remove pin (B) on both sides, slide reel asneeded and insert pins. Position both ends of thereel evenly on the support arms. Rotate reel byhand to check clearance with auger fingers andcutterbar.

IMPORTANT: Keep 1-inch (25-mm) minimumclearance between slats and cutterbar and slatsand auger fingers across entire width of platform.Less clearance can result in damage to reel slat.

3. Fore/aft Manual Adjusting Pickup Reel

NOTE: Reel is easier to move if support arms arelevel.

1. Raise reel and lower safety stops (A) on bothsides.

2. Remove pin (B) on both sides. Slide reel asneeded and insert pins. Position both ends of reelevenly on the support arms. Rotate reel by hand tocheck for clearance with auger flighting and knife.

3. The divider points limit forward position of pickupreel on flex platform. Check for clearance bymoving dividers up and down while turning reel byhand. Inner cover can be removed from divider toallow additional forward movement of reel.

IMPORTANT: Keep 1½ inches (38 mm) minimumclearance between tips of reel fingers andcutterbar; less clearance can result in cut offfingers. Also, keep fingers out of the ground orthey will take a permanent set.


Platforms - 2

4. Fore/aft Hydraulic Adjusting Reel (Attachment) This attachment will hydraulically position the reel.

The position of the reel is controlled from the cab.

If the cylinders become unevenly extended duringoperation, re-phase them by fully retracting thecylinders and holding control switch to remove airfrom system.

Be sure to position the pin at front of the cylindersso the reel will not get into the auger whencylinders are fully retracted.

IMPORTANT: Inner covers must be removed fromflex dividers to avoid damage to reel or dividers.Reel height must be checked with reel positioneddirectly above cutterbar.

5. Adjusting Pickup Finger Pitch The fingers must be vertical to cutterbar. Too great

of a pitch causes reel to carry or wind cut croparound the reel because fingers do not releasematerial after it is cut. Cut crop must be moved tounderside of auger and not pushed over top of it.The pitch on the pickup reel fingers can bechanged without changing position of reel onsupport arms.

1. Remove screw (A) (both ends of reel).

2. Loosen jam nut (B).

3. (For 13 ft. through 22 ft. Platforms) Turn bolt (C)on both ends for pitch.

4. (For 25 ft. and 30 ft. Platforms) Turn bolt (C) onright-hand end of reel for pitch.

5. Tighten jam nut.

6. Install and tighten screw (A) (both ends.


Platforms - 3

6. Adjusting Width Between Reel Arms The width between reel arms is adjustable to

center reel in platform and allows free movementof reel during fore/aft adjustment.

1. Loosen cap screw (A) on each end of platform

2. Move reel as needed to center reel lift cylinders (B)in opening (C) in end sheets.

3. Tighten cap screw (A) on each end of platform.

7. Adjusting Reel Height and Leveling ReelNOTE: Adjust reel height with cylinders fully retracted.

1. Remove quick lock pin (A).

2. Turn bolt (B) to adjust reel.

3. Install quick lock pin.

Checking reel height

IMPORTANT: Cutterbar Skid Plate tilt must be setbefore adjusting reel height.

When platform is equipped with hydraulic fore/aft,the reel height must be checked with reelpositioned directly above cutterbar on rigidplatforms and fully retracted on flex platforms.

Pickup Reel -- 1½ inches (38 mm) minimumclearance between the tips of the reel fingers andthe cutterbar must be kept. Less than this canresult in cut off reel fingers.

- On flex platforms, place a 4x4 board under thecenter and each end of the cutterbar.

- Lower header fully.

- Minimum clearance must be 1 to 1½ inches (38mm).

Slat Reel—Keep 1-inch (25-mm) minimumclearance between slats and cutterbar. Lessclearance can result in damage to reel slat.

8. Rephasing Reel Cylinders Always keep reel level with cutterbar.

If one end of reel is lower than the other, raise reel to the highest position or lower to the lowest position.

When both cylinders have been extended or retracted, return reel to original position and it will automatically belevel. If reel is not leveled, air is trapped in system and must be bled out.


Platforms - 4

9. Bleeding the System If hoses have been disconnected from cylinder or if

reel will not remain level with cutterbar, trapped airmust be bled from cylinders and lines.

This requires two people.

1. Open bleed plug (A) in cylinder on right hand side.

2. Raise reel and hold switch until oil is free of airbubbles.

3. Tighten plug.

IMPORTANT: Bleed plug must be tight or air willget into system again.


Platforms - 5

10. DIAL-A-SPEED™ (Attachment) The knob controls the ratio of the speed of reel or

the belt pickup to ground speed.

To operate:

1. Start the engine and drive forward with theseparator and header engaged.

2. Turn knob (A) to position 3.

3. Watch the speed of the reel or belt pickup andadjust the knob until you get the ratio toground speed that you want.

4. The reel or belt pickup will now speed up orslow down in relation to the ground speed.

The automatic control will not work if ground speedis less than 1.3 mph.

When driving the combine slowly through downand lodged crop, temporarily shut off this switchand use the manual reel speed switch (B).

To change the minimum speed:

1. Stop the combine and run the knob to the offposition.

2. Hold the manual switch to get the minimumreel or belt pickup speed you want.

3. Turn the knob to the check position.

4. Return the ratio knob to the prior setting andreturn to operating. This minimum speed iskept until the header is disengaged.

11. Reel Speed Dial 70 Series Combines Reel speed dial (A) will change speed of reel or

belt pickup as determined by operator.

Reel operating speed is a ratio of machine groundspeed to reel or belt speed.

Turn dial toward plus (+) symbol to increase reel orbelt pickup speed and or towards minus (-) symbolto decrease reel and belt pickup speed.

12. Speed Ratio Sensor Adjustment1. Remove shield.

2. Loosen two jam nuts (A).

3. Adjust sensor (B) until it touches tone wheel (C).

6. Adjusting Hold Down Clips Knife hold down clips (A) must keep elections from

lifting off guards (E) and permit knife (C) to slidewithout binding.

1. Set clips (A) after the guards (E) are aligned.

2. Tap clips (A) up or down until knife (C) willslide under clips without binding.

3. After setting clips (A), see that knife (C) worksfreely.


Platforms - 8

7. Aligning Guards Cutterbar must be straight before aligning guards.

1. Use a hammer and tap end of guard up or down toget shear cut between section and guard. Tightenbolt as each guard is aligned.

NOTE: Guard lip must be parallel with shear edge ofguard.

NOTE: Location of knife (A) as shown.

2. If replacing guards, align new guards to insure ashear cut.

8. Adjusting Auger Height

IMPORTANT: Before making any adjustments,raise platform until full weight of platform and reelis supported by the combine feederhouse.

For most conditions, adjust auger height to give aminimum clearance of 1/8-inch (3 mm) betweenflighting and bolt heads on floor or floor strippers.

Remove coupler chain and rotate auger by hand tocheck clearance along full length of auger.

IMPORTANT: Auger fingers must clear floor or flexsheet hold down bar at least 5/8 inch (16 mm).

1. On right-hand side of platform, loosen nuts(A), (B), (C), (D) and (E).

IMPORTANT: Auger fingers must clear floor or flexsheet hold down bar by at least 5/8 inch (16 mm).


Platforms - 10

10. Check Auger Stripper Location The auger strippers are positioned in different

locations depending on the combine size theplatform will be used on.

The inner end of the strippers must be aligned withfeederhouse opening auger stripper. Installstripper with inner hold of stripper support overhole (A) (third hole from center of platform floor).Secure stripper with cap screws.

(9400 & 9500 and 6620 Combines). Install stripperwith inner hole of stripper support over hole (B)(second hole from center of platform floor).

(4425, 4435, and 6620 Combines) Install stripperwith inner hole of stripper support over hole (C)(hole closest to the center of platform floor).

IMPORTANT: If the auger is too far from thestripper, material can be carried around the augerand will not be evenly fed into the feederhouse.

The auger must feed evenly to prevent wrapping ofthe feederhouse top shaft.

Adjust stripper clearance with the weight of theplatform supported by the feederhouse.

Adjust auger so there is ¼-inch (6 mm) minimumclearance between auger and fixed strippersupport.

1. Loosen screws (A) and slide stripper so thereis 1/8-inch (3 mm) clearance between augerand stripper.

2. Rotate auger by hand to check clearance asscrews are tightened.

3. The adjustable stripper bars are reversible toprovide additional wear life.

11. Adjusting Auger Finger Timing

IMPORTANT: Before making any adjustments,raise platform until full weight of platform and reelis supported by the combine feederhouse.

Feeding between the platform and feederhousecan sometimes be improved by advancing theauger finger timing.

1. Remove nut and bolt (A).

2. Loosen nuts (B).

3. Rotate casting (C) counterclockwise to movefingers to minimum of 5/8 inch (16 mm) to floor.

4. Torque nuts (B) to 85 ft-lbs. (115 N-m).

IMPORTANT: To avoid damaging floor or fingers:Maintain a minimum clearance between finger andfloor of 5/8 inch (16 mm). Keep nuts (B) tight.Rotate auger by hand to check clearances.

12. Auger Floor Strippers (Attachment) (Standard on 925 And 930 Rigid Platforms)

Floor strippers’ (A) help to stop material fromcarrying over the auger. This improves feeding ofmaterial to the feederhouse.

13. Auger Anti-wrap Shields (Attachment) These anti-wrap shields reduce the possibility of

straw wrapping around the auger shaft. They areavailable for rigid cutterbar platforms only.


Platforms - 12

14. Auger Flight Extensions (Attachment) Auger flight extensions are recommended for use

in short, slick straw conditions. The extensionshelp move crop closer to center of the feederhousefor even feeding to the cylinder. They can also beused in place of auger fingers to reduce wrappingof vines.

15. Adjusting Auger Chain1. Loosen nuts (A) and (C) and move tightener (B)

down to tighten chain.

2. Cutterbar Skid Plate Tilt Adjustment - FlexPlatform

IMPORTANT: Platform must be on combine andcutterbar locked out to make platform rigid beforeadjusting cutterbar tilt, leveling cutterbar, adjustingrange indicator and adjusting reel finger clearance.Adjusting tilt without first locking out the cutterbarwill result in erratic operation of the DIAL-A-MATICsystem.

The tilt adjustment is made for platform cutterbarskid plate to ground relationship. It is anadjustment made to compensate for tire size andother variables, but MUST also be used to makethe cutterbar straight.


Platforms - 14

Adjust as follows:

1. Lockout the flex cutterbar.

2. Loosen nut (B) about 1/16 inch (1.5 mm).

3. Adjust left-hand and right-hand tilt channels until there is ¾ inch (19 mm) of bolt showing at (A) between nut andbottom of pin. Hold the nut and tighten bolt.

4. Adjust stabilizer spring assembly before adjusting center tilt channels.

5. Use a string from one end to the other of the platform to align tips of the cutterbar guards, and then adjustremaining tilt channels until cutterbar is straight.

6. Hold nut (B) and tighten adjusting bolt (C).

7. Readjust range indicator to be centered over “0” on label.

8. Adjust reel for 1½ inches (38-mm) minimum clearance with cutterbar.

9. Check left-hand and right-hand side tire pressure or tire rim height; they should be equal.

10. Be certain platform is level referring to combine operator’s manual.

11. Remove lockout washers and bolts.

IMPORTANT: If cutterbar tilt change is required after making these initial adjustments, locking out thecutterbar will not be required as long as all tilt channels bolts are turned an equal amount.

5. Adjusting Cutterbar Drive Case SupportSpring (Flex Platforms Only)1. Remove cutterbar lockout bolts.

2. Tighten spring (A) until left-hand end of cutterbarrequires about the same lift force as right-hand endof cutterbar.

3. Readjust every time cutterbar tilt is changed.

6. DIAL-A-MATIC™ Header Height Control The DIAL-A-MATIC™ header height control

maintains the proper distance between the platformframe and the ground contour. This assures thatthe floating cutterbar is always within the 3½inches (90 mm) float range.

The system consists of multiple sensors that gaugethe relationship of sections of the cutterbar to theground. These sensors send electrical signals to avalue on the combine to raise or lower the platform.

The flexible cutterbar floats within a 3½ inch (90mm) range. When any one section of the cutterbarfloats higher than the rest, stop arm (A) movessensing pad (B) and causes height sensing rod (C)to turn. Actuator arm rests on top of stop arm,preventing turning of height sensing rod if onesection cutterbar floats down lower than othersections. This makes the highest section ofcutterbar control the DIAL-A-MATIC™ system.

DIAL-A-MATIC™ works as follows:

1. Height sensing rod (C) turns wiper arm (D) in sensing box (E).

2. Movement of wiper arm (D) contacts one of five printed circuit pads.

3. The pad that is touched starts system for raising or lowering platform.

4. When wiper arms touches ‘raise” pad, platform raises.

5. When wiper arm touches “lower” pad, platform lowers.

6. If fine tuning is required, loosen adjusting bolt (F) and rotate housing counterclockwise for heavier ground pressureand closer cut or clockwise for lighter ground pressure.

7. Tighten adjusting bolt (F).

7. Positioning Switch

The curved sheet between cutterbar and platform bottom operates as a leaf spring, supporting weight of cutterbar.When cutterbar is raised within its float range, tension is relieved from plate making cutterbar heavier and causing agreater ground force.

Dry ground conditions require a heavier ground force while soft or wet conditions require less ground force. The firstswitch position provides highest ground force and second and third positions provide less and less force.

The position of the DIAL-A-MATIC™ selector switch, determines where in the float range, the raise and lowersignals occur. There is a fixed dead band of 1-inch (25-mm) between raise (E) and lower (F) signals in all threepositions. The cutterbar can float within this dead band without generating a raise or lower signal.

If any one of the cutterbar sections is raised above (E), the system will give a raise signal. All of the cutterbarsections must lower below (F) before the system gives a lower signal. Since the ground is not uniform, some of thecutterbar sections will float to the bottom of range (C) while other sections are operating between (E) and (F).

Use first position whenever possible since this position gives the maximum use of the float range (closest cut) andbest feeding (sheet is flattest and cutterbar is closer to reel in this position). If platform pushes dirt or material atcenter or right-hand end, move switch to second or third position. If pushing starts at left-hand end, adjust cutterbarcase spring.

D. 900 Series Platforms – Rigid Adjustments1. Cutterbar Position The adjustable cutterbar is shipped in mid-position

that is suitable for most crops and conditions.Some harvesting conditions require cutterbar to berepositioned.

The extended position is for standing, toll, andheavy stemmed crops, such as grain sorghum, tallwheat and soybeans and for very short, light, drycrops. This position lets tall material fall and feedevenly under platform auger.

For short crops. Set reel to just clear the cutterbar.In this position, the reel sweeps material fromcutterbar that otherwise falls on the ground or layson cutterbar causing the knife to leave uncut straw.

Crops that are down and tangled, wet, or haveheavy weeds, cause slug feeding. For these cropconditions the cutterbar works best in the retractedposition. This position places the cutterbar near theplatform auger where the auger can easily movematerial before slugs form.

H. 600 Series Platforms – RigidAdjustments

1. Cutterbar PositionsNOTE: Rigid platforms are shipped from factory in theextended cutterbar position, which is suitable for mostcrops and conditions. To reposition cutterbar requiresa different knife drive belt, see your John DeereDealer for proper belt.

Some harvesting conditions require cutterbarto be repositioned.

NOTE: For short crops, set reel to just clear thecutterbar.

In this position, the reel sweeps material fromcutterbar that otherwise falls on the ground orlays on cutterbar causing the knife to leaveuncut straw (see Reel Adjustment section).

The extended position is for standing, tall,heavy stemmed crops such as grainsorghum, tall wheat, soybeans and for veryshort, light, dry crops. This position lets tallmaterial fall and feed evenly under platformauger.

NOTE: Retracted position is mainly used in rice.

The retracted position is for wet, tangled,down and that have heavy weeds. Thisposition places cutterbar near platform augerto allow easy flow of material before slugsform.

NOTE: In extended position, the center bolt is notsupplied with platform.

A. 900 Series Draper Platform Settings andAdjustments

1. Leveling Platform SuspensionIMPORTANT: Failure to properly make andmaintain this adjustment may lead to feedingproblems and result in machine damage.

1. Make sure combine is on a level surface.

2. Make sure transport chains are not hooked up.

3. Raise platform until leaf springs are approximately6” off the ground.

IMPORTANT: Turnbuckle length must betemporarily set to 493 mm (19.5 in.) while verticaltop beam spacing is set.

4. Set turnbuckle length to 493 mm (19.5 in.).

IMPORTANT: Distance from the main frame to thebottom of the straight edge must be the same onboth sides.

5. Lay a straight edge across the top of theattachment frame and extend it to the platformmain frame.

6. Measure down from the top of the mainframe tubeto the bottom of the straight edge. This dimensionshould be the same on each side of theattachment frame and normally adjusted to 140mm (5.5 in.).


Drapers - 2

7. If height adjustment is needed, place block (A)under the leaf spring saddle (B) on each side ofattachment frame and lower platform onto blocks.This will take the weight off the leveling screws (D)and allow easier adjustment.

8. Loosen jam nut (C).

9. Tightening screws (D) raises the mainframerelative to the attachment frame, while looseningscrews (D) lowers the mainframe relative to theattachment frame.

10. Tighten jam nut.

11. Repeat procedure on opposite side of platform.

12. Adjust turnbuckle to desired field setting (see CropAdjustment Chart below).

2. Leveling Draper Cutterbar to Ground

IMPORTANT: Do not use the draper suspension leveling screws to make this adjustment. Levelingscrews will improperly adjust the platform and will complicate related adjustments. This may lead tofeeding problems and result in machine damage.

Once the draper suspension system is leveled, the draper cutterbar relationship to the ground should bechecked. It is important to have the cutterbar level to the ground to insure a level cut of the crop material. Thiscan be very important when cutting close to the ground.

1. With the draper mounted to the combine and positioned on a level surface, lower the cutterbar(platform) until the cutterbar is approximately 457 mm (18 in.) off the ground.

2. Measure the distance from the extreme right knife guard to the ground. Repeat this measurement onthe extreme left-hand guard. If these two dimensions are significantly different, it may be necessary toreset the cutterbar level.

This adjustment is typically accomplished through combine feederhouse adjustments. Refer to FeederhouseAdjustments section for instructions on Header Leveling.

4. Platform Adjustment - FeedingIMPORTANT: Failure to properly level the drapersuspension system prior to making any of theadjustments discussed in this section may lead tofeeding problems and result in machine damage.

The key adjustments in this section, which influencedraper feeding, are dependent on proper suspensionsystem leveling. This is necessary because someadjustments influence other adjustments. To bestoptimize feeding, adjustments must be checked andmodified in the order listed above in step 3.

1. Platform Tilt (turnbuckle length)

2. Finger Timing

3. Feed Drum Height

5. Adjusting Cutterbar Tilt IMPORTANT: Adjusting the tilt adjuster to a length

less than 430 mm (17 in.) will reduce the distancebetween the center belt and side belt possiblycausing belt and center draper seal damage. It willalso decrease ground clearance at the leafsprings and attachment frame – pushing soilwhich can lead to center draper damage.

Failure to properly level the draper suspensionsystem prior to making any of the adjustmentsdiscussed in this section may lead to feedingproblems and result in machine damage.

1. A tilt adjuster is located between the main frameand the attachment frame. This tilt adjuster, whichchanges the cutterbar and side draper tilt, shouldnormally be adjusted to a length of 493 mm (19 ½in.). The tilt adjuster has a minimum length of 413mm (16 ¼ in.) and a maximum length of 574 mm(22 ½ in.). See Recommended Initial Crop Settingsabove.

2. Lengthening the tilt adjuster pivots the cutterbarforward and increases the drop from side belt tocenter belt, improving the feeding. It also lowersthe cutterbar of the platform increasing groundclearance at the leaf springs and attachmentframe. Tilting the platform forward also rotates theplatform moving the reel closer to the ground andextends the reel arm reach improving performancein down crops.

3. Shortening the tilt adjuster pivots the cutterbarrearward, raising the guard points off the groundand decrease the side belt angle.


Drapers - 5

6. Adjusting Feed Drum Finger Timing

IMPORTANT: To avoid damaging floor, feed belt orfingers, maintain a minimum clearance of 23 mm(7/8 in.) between feed drum fingers and center beltsplice (B) and between floor (A) and feed drumfingers.

Feed drum height must be readjusted wheneverplatform tilt, suspension leveling or finger timingis changed to insure adequate finger to center beltclearance and finger to floor clearance.

1. To change finger timing loosen three flange nuts(C) on the right-hand end of feed drum.

2. Rotate timing casting (D) clockwise to advance orcounter clockwise to retard timing. Hex shaft (E)extends out from the timing casting to allow theuse of a wrench to assist in rotating the casting.

3. Tighten nuts (C) to specification 60 Nm (44 lb-ft).

4. Verify adequate clearance exists between feeddrum fingers and center belt splice connectors.

7. Adjusting Drum HeightIMPORTANT: To avoid damaging floor, feed belt orfingers, maintain a minimum clearance of 23 mm(7/8 in.) between feed drum fingers, center beltsplice and between floor, and feed drum fingers.

Feed drum height must be readjusted wheneverplatform tilt, vertical top beam height or fingertiming is changed to insure adequate finger tocenter belt clearance and finger to floor clearance.

NOTE: A 30 to 40 mm finger to belt splice clearance isadequate for typical crop conditions. Tough or tangledcrop conditions may require a closer finger to beltsplice clearance. In certain heavy crop conditions, itmay be helpful to raise the feed drum so the feeddrum fingers can better grab the crop and provideadditional area under the feed drum.

Operating feed drum too high in light crop conditionsmay result in erratic feeding and side belt plugging.

1. (BOTH SIDES): Loosen the jam nuts (A) on thehanger bolts (B) at each end of the feed drumand then raise or lower the feed drum float arms(C) equally.

2. Tighten jam nuts (A) to specification(115 Nm (85 lb-ft).

8. Adjusting Draper Side Belt Position The position of the side draper belt assemblies can be

adjusted to improve feeding characteristics in certaincrop conditions.

In normal/dry conditions, the belt assemblies are bestpositioned in the outward positions (frame mountholes provided). If the belt assemblies will always beused in this position, the rubber extensions attachedto the end sheet crop deflectors may be removed toimprove material flow at the end sheets.

When harvesting in heavy, damp crops, positioningthe side belts to the inward mount holes can improvematerial flow at the center belt and feed drum.

1. Loosen back sheet clamps (A) as required.

NOTE: Both side belts of the 25 ft. platform and theright-hand side belt of the 36 ft. platform (to offsetextra material flow on right-hand belts) are shippedfrom the factory in the inward position. Mount holesare provided in the frame for both positions on allmodels.

2. Remove cap screws (A)

3. Both Sides: Push side frames in or out as requiredup to 101 – 127 mm (4 – 5 in.). Check to makesure adequate clearance to the feed drum fingersin maintained.

4. Use mounting hole seen through slot (A) toreinstall cap screw (B).

5. Tighten back sheet clamps (A) as requiredmentioned in step 1.

9. Adjusting Draper Side Belt Tensioner

NOTE: In wet or heavy crop conditions, additional belttension may be required to prevent belt slippage.Increase belt tension only as required as belt life isaffected. Do not adjust face of spring more than 50mm (2 in.) past tensioning gauge.

1. Tighten screw (A) until outward spring face (D) ofspring (C) is the same length as gauge (B).

10. Adjusting Draper Center Belt Tensioner

CAUTION: When working under the platformalways place the hydraulic cylinder safetystop in the safety position to prevent headerfrom lowering.1. Raise feeder house and lower safety stop (A) onto

hydraulic cylinder.

2. Shut off engine, set parking brake and remove key.

NOTE: For difficult crop conditions additional belttensioning may be required. Do not increase thecenter belt tensioning dimension (B) to greater than 50mm (2 in.) as belt life will be affected.

3. Adjust center draper belt tensioner (A) to 25 mm (1in.) (B) as measured from outside edge of guard toend of spring cap (C).

4. Check operation of center draper belt and recheckbelt tensioner to ensure proper tension is stillapplied to belt.


Drapers - 8

11. Sump PanNOTE: Sump pan can be installed to reduce theaccumulation of crop material and improve theappearance in the area directly between the cutterbar and center feed belt

If side belts are in the inward position, temporarilyslide side belts to the outward position to aid ininstalling sump pan.

1. Install sump pan in groove (B) on center draperframe floor.

2. Pull sump pan up and forward over cutterbar,retain with cap screws (A).

3. Reverse steps to remove.

12. Platform Adjustment – Cutting The knife drive and cutting systems for

draper platforms are similar to those on 600Series Platforms. Refer to the 600 SeriesPlatforms section for knife drive, sickle, andguard settings and adjustments.

13. Draper Belt Speed: In-Cab

One adjustment changes all belt speedsproportionately up or down. The belt speedshould be set for the prevailing crop conditions,with the objective being an even distribution ofcrop material across the usable width of centerfeed belt. This will provide an even distribution ofcrop material across the entire separator width.

2. Finger Timing


Drapers - 12

7. Adjusting Cutterbar TiltIMPORTANT: Failure to level the draper float systembefore making any of the adjustments discussed inthis section can lead to feeding problems and resultin machine damage.

NOTE: Lengthening the tilt adjuster pivots the cutterbarforward and increases the drop from side belt to centerbelt, improving the feeding. It also lowers the cutterbar ofthe platform increasing ground clearance at the hydraulicfloat cylinder brackets. Tilting the platform forward alsorotates the platform moving the reel closer to the groundand extends the reel arm reach improving performancein down crops.

Shortening the tilt adjuster pivots the cutterbar rearward,raising the guard points off the ground and decreasesthe side belt angle.

Draper cutterbar tilt adjust switch (A) allows the operatorto increase or decrease the draper cutterbar angle.

1. Press draper cutterbar tilt adjust switch (A).

2. Indicator light (B) will illuminate indicating setting canbe adjusted.

3. Turn selection dial (C) towards plus (+) symbol to tiltcutterbar down or towards minus (-) symbol to tiltcutterbar up.

4. CommandCenter display will show operatoradjustment setting.

8. Adjusting Feed Drum Finger TimingFor most crop conditions, operate feed drum with thefingers fully advanced (finger timing rotated fullyclockwise as viewed from the right-hand end). If cropmaterial is being pulled up behind the feed drum orexcessive grain is being threshed, retard finger timing(rotate counter clockwise).

When harvesting dry high volume crops, rotate the fingertiming counterclockwise in 10 degree increments toprevent material bunching in front of the feed drum ormaterial appearing to go over the feed drum. Continuemaking adjustments until the crop flows under the feeddrum smoothly.

1. To change finger timing loosen three flange nuts (A)on the right-hand end of feed drum.

2. Rotate timing wedlment using handle (B) clockwiseto advance or counter clockwise to retard timing.Hex shaft (C) extends out from the timing casting toallow the use of a wrench to assist in rotating thecasting.

3. Tighten nuts (A) to specifications…60 N•m (44 lb-ft)


Drapers - 13


NOTE: In wet or heavy crop conditions, additional belttension is required to prevent belt slippage. Increase belttension only as required as belt life is affected.

1. Tighten tension nut (A) so the surface of the nut isflush with the outside surface of the plate (B).


CAUTION: When working under the platform alwaysplace the hydraulic cylinder safety stop in the safetyposition to prevent header from lowering.

1. Completely raise feeder house and lower safety stop(A) onto hydraulic cylinder.

2. Shut off engine, set parking brake and remove key.

NOTE: For difficult crop conditions, additional belttensioning is required. Increase belt tension only asrequired as belt life is affected.

3. Adjust center draper belt tensioner (A) so that springwasher (B) is just inside the edge of guard (C).

4. Check operation of center draper belt and recheckbelt tensioner to ensure that proper tension isapplied to belt.

11. Draper Reel Settings for Crops

In tall standing crop, position reel above the cutterbar.Raise reel until bats and fingers strike just under thegrain heads to help guide crop into cutterbar and ontobelts.

In short, damp or weedy grain crops, move reel back anddown to help pull crop off cutterbar and onto the belts.

IMPORTANT: Do not position reel too far forward.Reel must feed the cut crop onto the side belts.Material buildup and slugs result if reel is positionedtoo far forward.

1. Pickup Reel – In crops that are down and tangled:reel must be set low and ahead of the cutterbar tohelp lift the crop while guiding the cut crop onto thebelts. Ensure reel fingers cannot contact cutterbar.

2. Finger Recommendations in Down Crop –position finger angle so that the fingers lift the crop,but not so much as to carry crop around reel.

3. Finger Recommendations For Standing Crops –position finger angle so that there is minimaldisturbance to the crop when entering; helping thecrop onto the belt.

4. Reel Speed – Set reel tip speed (slats or fingers)slightly faster than ground speed.

Excessive shattering of grain heads, ormaterial carrying around reel, indicates thatreel speed is too fast.

Cutterbar plugging, flagging, or slug feedingindicates reel speed is too slow.

In down, tough crop condition, a faster reelspeed is necessary to “comb” the crop. Slugfeeding at the cutterbar (or poor feeding)indicates that the reel is adjusted too farforward, too high, or too slow.

12. Platform Adjustment – CuttingThe knife drive and cutting systems for draperplatforms are similar to those on 600 Series Rigidand Flex Platforms. Refer to the 600 SeriesPlatforms section for knife drive, sickle, and guardsettings and adjustments.

A. Feederhouse Adjustment (9000, 9010and 50 Series Walker Combines)

1. Header Leveling Check that tires are inflated to equal pressure,

and with the header raised, take a positionapproximately 5 M (15 ft.) in front of the combine.Compare the bottom of the header with thebottom of the front axle. They should be parallel.

If the header is not level, the only adjustment thatis required is to remove the header, and movethe shims (B) on the top beam of thefeederhouse from one side to the other asnecessary to level the header.

If the header is not level, more crop will be takenin on the low side and will cause uneven feeding. A - Nuts

B - Shim

2. Adjusting Feederhouse Front Drum Height Conveyor chain must be 3 mm (1/8 in) for grain

and 25 mm (1 in) for corn as measured betweena conveyor slat and feederhouse bottom, directlyunder the feed drum.

Adjustment cams are located on both sides offeederhouse. To set height:

1. Loosen nut (A).

2. For small grain, rotate bolt until hole (B)aligns through side sheet. A wrench flat isprovided on bolt.

3. For grain slat clearance, loosen nut (C) androtate cam (D) to get 3 mm (1/8 in) slatclearance between slat and feederhousebottom on both sides.

4. To get the 25 mm (1 in) clearance for corn,loosen nut (A). Rotate bolt until hole (B) isaligned in upper end of slot. Torque nut (A)to 115 N-m (85 lb-ft).

5. Retighten nut (A) and (C).

6. Cam (D) is not adjusted for corn.

If the feeder drum is not level, more crop will betaken in on the wide side and will cause unevenfeeding to the cylinder/concave.

A kit (AH210753) is available to make thisadjustment without tools by turning a handle (seeFeederhouse Drum Height Adjustment underFeederhouse 60 Series for operation).



3. Adjusting Feeder Conveyor Chain

NOTE: Chain adjustment must be done with headerattached.

Set feederhouse front drum height to grainposition.

1. Remove left hand side feederhouse shield.

2. Adjust eyebolt (A) until left and right handside outer chains just touch wear strip (B).This setting is the tightest the chain shouldever be run.

Do not over tighten chain to make center strandsas tight as outer strands. Center strandsnormally sag more because of weight of slats andupward force from crop material.

Bent eyebolts indicate excessive chain tension orslug feeding.

Excessive chain tension will cause the front drumto raise when bunches of material enter thefeederhouse, reducing even feeding.

Out-of-round sprockets or drum and bent shaftscan cause chain tension to be uneven, too tightor too loose.

Shaft and bearing failure are often caused byexcessive chain tension.

When the adjusting eyebolt can go no further andthe chain needs more tensioning, remove a halflink.

4. Removing Conveyor Chain Links First adjustment (Approximately 500 Hrs):

Remove offset links (A) for initial chainadjustment.

Second adjustment (Approximately 1200Hrs):

Remove inside link (B) and replace it with anoffset link. Order AH137631 (C) [(3) for9400/9500 Combines] or (4) for 9600 Combines].The offset link now becomes the coupler link.Remove the top shaft end for end at the samethe links are installed. Repeat this procedure onall strands of chain.

When adjustment is all used up from secondadjustment, the chain is worn out and should bereplaced.



5. Changing Feeder Conveyor Speed(9000,9010 Walker Combines)1. Loosen nut (A) and push idler sprocket forward.

2. Loosen setscrew (D) to slide drive sprocket.

3. Slide the double sprocket over to align smallsprocket with top sprocket. It may be necessaryto remove a link or two.

4. Push idler sprocket rearward and tighten nut (A).

Running the drive chain on the small sprocket(slow speed) is the recommended position forALL crops. The large sprocket (high speed) isavailable for unique crop conditions.

The variable speed feederhouse also changesthe speed of the corn head or row-crop head. If itis used with a platform, the drive must be slowedall the way down to prevent rapid wear ofcutterbar parts.

6. Adjusting Feeder Conveyor Drive Chain(9000,9010 Walker Combines)1. Loosen nut (A)

1. Remove top feederhouse door.

2. Loosen bolts (A) and set stripper (B) to 7 mm(1/4 in) (C) from top shaft (D).

3. Tighten bolts (A) and replace top door.

If the gap is too narrow, the shaft will interferewith the stripper. If it is too wide, thefeederhouse shaft may wrap with crop.

10. Slip Clutch

A non-adjustable slip clutch protects the uppershaft.

If the slip clutch is removed, tighten flange nut (A)and locknut (B) to 350 N-m (258 lb-ft).



11. Adjusting Variable Speed Feederhouse Belt

IMPORTANT: A gap between lower sheavehalves is important so sheave halves can gripbelt when in slow speed position. Cuttingplatform driveshaft speed must be at slow speed.

1. Remove left-hand side feederhouse shields.

2. Adjust the feederhouse drive belt to get the slowfront shaft speed for the cutting platform.

3. Start engine, engage separator and header. Slowfeederhouse all the way down.

4. Turn off separator, stop engine and remove key.Look underneath rubber boot (A) to see if uppersheaves are fully open.

5. Check lower sheave gap for 3mm (1/8 in.)clearance. If not correct, move idler (B) to 25 mm(1 in.) from bottom slot, loosen bolts (C).Recheck lower sheave gap. If it is not 3 mm (1/8in.), then:

6. Move upper variable sheave assembly back withjam nuts on rod (D) until 3 mm (1/8 in.) gap existsbetween lower sheave halves, or until uppersheave assembly reaches end of slots. Tightenbolts (C). Adjust feederhouse belt idler (B) up totighten belt.

A—Pivot Bolt



2. Feederhouse Conveyor Chain—Adjusting1. Open feederhouse side shields.

2. Set conveyor drum height adjust handles to smallgrain position.

3. Loosen nut (A) on both sides of feederhouse.

IMPORTANT: Do not over-tighten chain to makecenter strands as tight as outer strands. Centerstrands normally sag more because of weight ofslats and upward force from crop material.

4. Adjust eyebolt (B) with adjustment nuts (C) onboth sides of feederhouse until left-hand andright-hand side outer chains contact runner at thecenter (F) of inspection door (D).

Check tension on both sides every 100hours. Adjust when outside strands touchfront of runner channel (E). Adjust no tighterthan runner contact (F) at center forinspection door.

Do not over-tighten chain to make centerstrands as tight as outer strands. Centerstrands normally sag more because ofweight of slats and upward force from cropmaterial.

Bent eyebolts indicate excessive chaintension or slug feeding.

Out-of-round sprockets or drum and bentshafts can cause chain tension to beuneven, too tight, or too loose.

Shaft and bearing failure are often caused byexcessive chain tension.

When adjusting eyebolt can go no furtherand the chain needs more tensioning,remove a half link.

Close feederhouse side shields.



3. Feederhouse Drum—Height Adjustment

NOTE: The retracted swing cylinder is intended to bethe top for the auger. DO NOT use the pin or witch as astop. The pin is intended ONLY to aid in absorbingvertical load of the auger in transport position. Theswitch is intended ONLY to shut off electrical power tothe hydraulic solenoids.

Make the following adjustments ONLY when the augerdoes not swing completely back or fails to shut off thehydraulic system.

1. Swing auger all of the way in.

2. Be certain there is a 12 to 16 mm (1/2 to 5/8 in.)gap between plate (A) and stop (B) when stud (C)is in hole (D). If there is no gap, the hydraulicsystem may not shut off.

3. If the gap is incorrect, loosen nut (A) and removecotter pin (B) and pivot pin (C). Screw cylinder rodfitting (D) in or out to obtain correct gap (cylinderrod must be completely retracted). Replace pivotpin and cotter pin. Tighten nut.

NOTE: Applying grease on pivot pin and swingingauger in and out may aid in determining gap.

STS Feederhouse -1

A. Feederhouse Adjustments (50 SeriesSTS Combines)

1. Header Leveling Check that tires are inflated to equal pressure,

and with the header raised, take a positionapproximately 5 M (15 ft.) in front of thecombine. Compare the bottom of the headerwith the bottom of the front axle. They shouldbe parallel.

If the header is not level, the only adjustmentthat is required is to remove the header, andmove the shims (B) on the top beam of thefeederhouse from one side to the other asnecessary to level the header.

If the header is not level, more crops will betaken in on the low side and will cause unevenfeeding.

2. Adjusting Front Drum Float The front drum has two positions and must be

set correctly. If drum is not level or not set inthe correct position, material will be fedunevenly to the threshing area and bunching orslug feeding could occur.

The conveyor chain slat clearance must be3mm (1/8”) for grain and 25mm (1”) for corn.

This measurement is made between theconveyor chain slat (A) and the feederhousebottom. Slat must be directly under the center ofthe drum when this check is made.

Float cams are located on both sides of thefeederhouse. To set float position:

1. Loosen nut (A).

2. For small grain, rotate bolt until hole (C)aligns through side sheet. A wrench flat isprovided on the bolt (B).

3. For grain slat clearance, loosen nut (E) androtate cam (D) to get 3mm (1/8”) slatclearance between slat and feederhousebottom on both sides.

4. To get 25mm (1”) clearances for corn,loosen nut (A) and rotate bolt until hole (C)is aligned in upper end of slot.


STS Feederhouse -2

3. Adjusting Feeder Conveyor Chain1. Set the front drum “float” to the grain position.

2. Adjust eyebolt until left and right hand side outerchain just touches the runner at the center of theinspection door. The chain should be no tighterthan runner contact at the rear of the dooropening; see decal inside inspection door.

Do not over-tighten the chain or try tomake center chain as tight as the outerchains. The center chain normally will sagmore than the outer chains because of theadded weight slats and upward force fromcrop material.

Shaft and bearing failure are often causedby excessive chain tension. Tight chainswill lead to premature chain and sprocketwear.

When the adjusting eyebolt can go nofurther and the chain needs moreadjustment, remove a half link from thechains. (Refer to Operator’s Manual)

4. Changing Feederhouse Conveyor Speed The feederhouse is shipped from the factory

with the chain on the large sprocket for highfeeder conveyor speed.

For corn, install the chain on the small (15tooth) sprocket. For other crops, install thechain on the large (22 tooth) sprocket.

To switch drive sprockets:

1. Loosen nut (A) and push sprocketrearward.

2. Loosen nut (B), move adjusting-sprocket tocenter position.

3. Slide collar on sprocket assembly torelease locking detent. Move assembly onshaft to align selected drive sprocket withupper sprocket. Collar must return tooriginal locking position. Install chain.

To adjust chain tension, loosen nut (A) andpush sprocket forward to remove slack fromchain. Improper adjustment will result inpremature wear of the chain and sprocket.Tighten nut.


STS Feederhouse -3

5. Feederhouse Top Shaft StripperAdjustment If the top feederhouse shaft should wrap, check

to see that the strippers are adjusted as follows:

1. Remove top feederhouse door.

2. Loosen bolts and set stripper to 3mm(1/8”) from top shaft.

3. Tighten bolts and replace top door.

6. Adjusting Variable Speed Feederhouse Belt When using a cutting platform the front shaft

must be set to run at 520 rpm.

Start the engine, engage separator and moveswitch to fast idle. Slow the feederhouse all theway down to its slowest speed. The belt shouldbe all the way to the outer OD of the sheavehalves.

Check the lower sheave gap for 3mm (1/8”)clearance.

IMPORTANT: A gap between sheave halves isimportant so sheave halves can grip belt whenin slow speed position. Cutting platformdriveshaft speed must be at slow speed.

If the sheave gap is not 3mm (1/8”), refer to theOperator’s Manual for proper adjustingprocedure.

7. Adjusting Fixed Speed Feederhouse Belt Tighten nuts until washer aligns with the end of

gauge. Improper adjustment may cause beltslippage and or belt failure.

STS Feederhouse -8

2. Adjusting Feederhouse Conveyor Chain1. Open feederhouse side shields.

2. Set conveyor drum height adjust handles tosmall grain position.

3. Loosen nut (A) on both sides of feederhouse.

IMPORTANT: Do not over-tighten chain to makecenter strands as tight as outer strands. Centerstrands normally sag more because of weightof slats and upward force from crop material.

4. Adjust eyebolt (B) with adjustment nuts (C) onboth sides of feederhouse until left-hand andright-hand side outer chains contact runner atthe center (F) of inspection door (D).

Check tension on both sides every 100hours. Adjust when outside strands touchfront of runner channel (E). Adjust notighter than runner contact (F) at center forinspection door.

Do not over-tighten chain to make centerstrands as tight as outer strands. Centerstrands normally sag more because ofweight of slats and upward force from cropmaterial.

Bent eyebolts indicate excessive chaintension or slug feeding.

Out-of-round sprockets or drum and bentshafts can cause chain tension to beuneven, too tight, or too loose.

Shaft and bearing failure are often causedby excessive chain tension.

When adjusting eyebolt can go no furtherand the chain needs more tensioning,remove a half link.

Close feederhouse side shields.

On later model 70 series combines only removefeeder house shields on both sides.

Tighten nut (A) on both sides of feederhouse until washer (B) is positionedbetween end of gauge (C) and bottom ofstep.

Use small sprocket for low speeds and largesprocket for high speeds.


STS Feederhouse -11

Important Notes About Running With 32 Tooth Sprocket:

32 tooth sprocket is not recommended for corn.

32 tooth sprocket can be used on both fixed and variable speed feederhouse drive. The variablespeed drive MUST be set to the slowest speed 520 RPM.

32 tooth sprocket is to be used in conditions when feeding is poor due to the following crops andconditions:

Crops: Barley, Oats, Rice, Rye and Wheat

Conditions: High Volume, Green, Wet, Windrowed and Poor Feeding

If conditions are not tough, or as conditions change to improved feeding (dryer, more even windrows,lighter straw), it is recommended to change to the 26 tooth sprocket. This will slow the chain speed, whichreduces potential for straw damage or pre-threshing and extends life of feederhouse chain.

6. Attach Multi-Coupler and Single PointLatchingIMPORTANT: Latch pins are not to be actuatedwith header on the ground. If multi-couplermust be actuated with header on ground,unhook cable from handle.

1. Remove cover (A) and clean multi-coupler face(B).


STS Feederhouse -12

2. Open handle (A) and remove multi-coupler (B)from storage bracket (C).

NOTE: To prevent damage to the latching cable, ashear screw is attached to the handle. Attempts toactuate the latching pins with the header on theground will shear the screw on the handle. Extrashear screws are located on the combine side ofthe multi-coupler.

3. Install multi-coupler (A) onto receptacle (B) onfeederhouse and close handle (C).

4. Install multi-coupler cover on platform multi-coupler bracket.

1. Feed Accelerator Speed

The feed accelerator can be run at two differentspeeds, 440 and 800 RPM. The slow speed isused for material conveyance in all crops. Thehigh speed can be used to enhance materialhandling in heavy tough crop conditions.

There is also a Feed Accelerator Slow SpeedDrive. It is recommended for food corn,popcorn and edible beans. It has a speedrange of 320 and 770 RPM.

The feed accelerator on rice machines andmachine with the High Capacity Feed Packagehas speeds of 510 and 1000 RPM.

NOTE: For harvesting food corn and popcorn dothe following. Install the feed accelerator slowdown kit (BH81691) for grain quality. Install smoothwear strips on the feed accelerator. (BH81489) forgrain quality.

NOTE: Normally, the slow speed attachmentshould be used with smooth wear strips (as aboveNOTE indicates). For difficult feeding conditionsas in edible beans, serrated (with edges worn off)or serrated swept back wear strips can be used.

Feed Accelerator Slow Down Kit

2. Feed Accelerator Wear Strips

Standard Feed Accelerator wear strips areserrated. Two other wear strips are availablefor specialty crops.

The smooth wear strips (A) are the leastaggressive option. They are recommended incrops that have minimal material handlingchallenges.

The serrated swept back wear strips (B) have aleading edge that is rounded for grain quality,yet have a serrated trailing edge to grab stems,straw, and vines to feed material into thecombine.

When the leading edge becomes nearly halfworn down, both the standard serrated andsmooth wear strips can be reversed for longerwear life.

18. Threshing Elements and Tine – Removaland Install

IMPORTANT: STS Rotor is a balancedassembly. Elements and tines must bereplaced in sets of three to maintain balance.Replacement kits are available through serviceparts and include new cap screws with pre-applied LOCTITE™ 204. Always use new capscrews and do not re-tighten after initialinstallation. Tines or elements that becomeloose may result in machine damage. If tines orelements need to be removed for other thanreplacement, mark location ontine(s)/element(s) and rotor, prior to removal.Install in same location as removed to maintainbalance. Always use new cap screws. Makesure to clean out tailings and front cross augerif tine replacement is due to broken or damagetines. Failure to do so before initial start-upmay allow broken tines to re-circulate andcause tine damage to reoccur.

1. Remove separator grates or concave sectionsas needed to access STS Rotor.

2. Inspect wear on threshing elements andseparator tines using AH204933 STS CombineClearance Gauge (except for rice elements).

Check tines for wear and replace tines iftine height is less than 114 mm (4½inches).

Check elements for wear and replace ifnecessary.

If one element or tine needs replaced,replace all in the group. Example: Ifelement 2 needs to be replaced, replaceelements 1 and 3 also. Use ThreshingElements and Separator Tine Locationdiagram in Operator’s Manual foridentifying elements and tines.

3. Remove cap screws (A) and threshingelement or tine.

19. Rotor Discharge Flights

Install the rotor discharge flight bundle(BH84581) when operating in conditions thatrequire rotor speeds below 300 rpm (e.g.sunflowers, edible beans). The dischargeflights mount directly to tine positions 21 and22 and are designed to provide an aggressive“push” to the slow-moving crop material as itmoves from the rotor housing into thedischarge beater to improve material flow andreduce the possibility of plugging at the rear ofthe rotor.

When operating in crops where rotor speedsare above 300 rpm (e.g. soybeans, wheat, rice,etc.), remove the discharge flights to ensureadequate and even material flow through therotor and better residue spread.

20. Deep Tooth Fixed Front ChafferThe deep-tooth front chaffer is fixed and set at 24mm (15/16 in.)

1. Insert tool through slot in side sheet andengage slotted end of crank with cross pinin chaffer or sieve.

2. Turn crank clockwise to open

3. Turn counter-clockwise to close louvers.

4. Observe setting on outside indicator ofchaffer or sieve for direct readout of louveropening.


STS Combine -17

28. Calibration of Indicator

Open the louvers to any position and measurethe opening in millimeters.

1. Loosen setscrew (A) at the rear left handcorner of the chaffer (opening in chafferframe).

2. Move indicator on the outside of the sidesheet until the measured opening amountlines up with side sheet.

3. Tighten setscrew at the rear of chaffer. Usethis procedure to also calibrate the sieve.

29. Chaffer/Sieve Adjusting Switch (Optional)

Chaffer adjust switch (A) and sieve adjustswitch (B) are located on left-hand side ofcombine above separator shield if the combineis equipped with TouchSetTM AutomaticCombine Adjust system.

Chaffer adjust switch and sieve adjust switchallows the operator to open or close the chafferand sieve to various positions from the side ofthe machine.

Switches are also located on the armrest tomake chaffer and sieve opening adjustmentsfrom the cab.

30. Air Chutes & Agitators

Air chute allows the shoe to breathe morefreely especially when the chopper is runningon low speed. Depending upon harvestingconditions, grain tank quality may be enhancedand feeder house dust reduced.

Air chute agitators are bolted to the chafferframe and move with the shoe as it shakes tokeep material from building up and pluggingthe air chute. By reducing the material buildup, the air chute agitators can help maintain acleaner grain tank.


STS Combine -18

31. Clean Grain Elevator

The clean grain elevator on all STS combinesare now a one-piece design to reduce thenumber of wear points.

It has 20% more capacity than the 10 Seriesclean grain elevator and is standard on theentire 50 Series combine family.

Bolt-on paddles are standard for easierreplacement.

Drive belt capacity is also increased to providemore performance.

All clean grain elevators on 50 Seriescombines are GreenStar™ compatible.

Chain tension that is too loose will not properlyconvey material and can pinch grain.

To adjust chain tension

1. Loosen four nuts (A).

2. Move bearing carrier downward by movingnuts on bolt (B).

3. Elevator chain is adjusted properly whenlower end of chain can be slid side to sideon the sprocket. When chain loosens up to6mm (1/4 inch) away from sprocket,readjust chain.

32. Adjusting Tailings Elevator Paddle Chain

Proper chain tension is also important tomaintain on the tailings elevator as well as theclean grain elevator.

1. Release latch and open lower door.

2. Loosen four nuts.

3. Use nuts to adjust chain.

4. To tighten chain move bearing carrierdownward.

5. Elevator chain is adjusted properly whenlower end of chain can be slid across thesprocket. When chain loosens up to 6mm(1/4in.) away from sprocket readjust chain.


STS Combine -19

33. Chopper

CAUTION: Do not let anyone stand behind thechopper while it is running. Combine engine mustbe off, parking brake set and key removed beforeadjusting chopper. Before performing service ormaintenance on raised chopper, use lift actuator tosnap lockout pins into place. Normal use wearsthe bottom of the chopper fins to a sharp edge.

1. For Chopper High Speed:

Grain with tough or green straw

Larger platforms

2. For Chopper Low Speed:

Corn

Grain with dry straw

Smaller platforms

NOTE: Less power will be consumed and bladelife will be increased with the chopper on lowspeed.

1. Start with the chopper on low speed andknife bank out.

2. If cut length is not fine enough the firstadjustment should be to slide the knifebank in.

3. If cut length is still not acceptable thenchopper should be placed on high speedand knife bank out.

4. Final attempt at reducing residue lengthshould be chopper on high speed and knifebank in.

To change from one speed to another:

1. Disengage tension on the belt by raisingthe belt tensioning arm (B).

2. Move double belt to pulley set with thesmaller driven pulley (lower pulley onchopper rotor shaft) for high speed or withthe larger driven pulley for low speed.

Arm down with belt tensioned

Arm up and no tension on belt


STS Combine -20

34. Cob Deflector

The cob deflector should be removed todecrease light foreign material in the grain tankand allow material to flow freely into thechopper in crops other than corn andsunflowers.

Remove five round head screws and two-flange head screws and remove cob deflectoron early 50 Series combines.

On late model 50 Series and all 60 and 70Series combines, this adjustment is a hingedhandle on the right side just before thechopper. (A)

IMPORTANT: Reinstall cob deflector for cornand sunflowers to prevent damage to cleanerelements.

E. HELPFUL HINTS FOR SOYBEANS HARVEST (WALKER COMBINES)

Flex Platform:

Properly level the platform to the combine. Set platform auger flighting to correct clearance of platform floor and to the floor and rear strippers for

even crop movement. For 25 and 30 foot platforms, the third stripper is factory installed on 2006 platforms. This should be

added to older 600 Series platforms to improve feeding resulting in increase harvesting capacity. Set reel so that it sweeps the crop off the cutter bar in a smooth even fashion – this also helps prevent

bunch feeding into the feederhouse.

Feeding:

The feederhouse front drum should be in the (grain) DOWN position 1/8 inch (3-4mm) for good even cropmovement.

The feederhouse conveyor chain speed sprocket should be set on the SMALL sprocket. A 32/26 toothsprocket (in the “High Capacity Feed Package”) can be obtained if needed to improve feeding in toughwet conditions for the 50 and 60 series walkers (CAUTION – Can cause increased feeder house chainwear).

Threshing:

Make sure raspbars do not have a rough surface that will damage the crop. Use raspbars with at least100 acres of operation on them to remove sharp edges.

Remove cylinder filler plates. Check to make sure concave is level (side-to-side), see Operators Manual for details. Excessive cylinder speed causes grain damage. Tighter concave clearance can increase threshing. Concave Inserts can reduce unthreshed pods on the cleaning shoe.

Separating:

Beater grate in the UP position. Beater grate curtains installed. All straw walkers should have a full complement (4-per walker) of straw walker risers.

Cleaning:

Use regular tooth chaffer and sieve. Pre-cleaner closed. Adjust fan speed to recommended settings. Too fast fan speed will blow crop into tailings.

Usually running the chaffer extension at the same setting as the chaffer reduces the amount of material intailings.

Grain Handling:

Check augers and elevator chains for wear and sharp edges. Replace as necessary. Adjust elevator chains for proper tension. To reduce the potential for grain damage, do not use screens on the clean grain and tailings augers,

elevator doors, and unloading auger. To reduce the potential for grain damage, do not fill the grain tank above the loading discharge auger. Install grain tank cross auger cover extensions on the grain tank cross auger covers to reduce pressure

on the cross augers. Adjust the covers to the mid-position. Do not completely unload the grain tank. Grain damage can occur due to the vertical unloading charge

housing and other augers not being full during start-up.

Cleaning:

Use regular tooth chaffer and sieve.

Adjust fan speed to recommended settings.

Grain Handling:

Check augers and elevator chains for wear and sharp edges. Replace as necessary.

Adjust elevator chains for proper tension.

To reduce the potential for grain damage, do not use screens on the clean grain and tailings augers, elevatordoors, and unloading auger.

To reduce the potential for grain damage, do not fill the grain tank above the loading discharge auger.

Install grain tank cross auger covers in the UPPER position on the Standard and High unloading systems.

Do not completely unload the grain tank. Grain damage can occur due to the vertical unloading chargehousing and other augers not being full during start-up.

Residue Management:

Straw Chopper belt in the HIGH speed position.

Adjust stationary knife to desired straw length.
