Safety Instructions
Your slasher operates with rotating blades at high speed - the following safety precautionsshould be observed at all times.
Stand clear of equipment whilst in operation or in a raised position. Keep body clear ofmoving parts at all times.
DO NOT operate damaged or FAULTY equipment.
Ensure protective shields and covers are in place before use. Do not remove any guards orcovers whilst the slasher is in operation.
DO NOT perform service or maintenance on this equipment whilst the PTO is engaged, orthe tractor engine is on.
Disengage the PTO when transporting the slasher, or when not in use.
Take care when leaving the tractor. Ensure the slasher is in the lowered position, the PTOis disengaged, the tractors parking brake is on, the tractors engine is off and the key removed.
DO NOT allow passengers on the tractor or slasher when operating. Onlookers shouldmaintain a safe minimum distance from the slasher when in use of 50 metres.
Never touch the blades or blade beam when the tractor engine is running. Turn the engineoff first and disengage the PTO.
If performing maintenance on the slasher whilst it is held on the tractors 3 point linkage,ensure that the slasher body is properly supported by blocks or stands under the body
Before commencing operation of the slasher, ensure that all obstructions (such as stumps,stones, bottles, tins, wires etc.) are removed from the area.
If operating slasher beside public pathways, in parks or gardens, or in any area in theproximity of people, take special precautions to ensure safety. Carefully inspect ground forobstructions, and discourage all spectators when operating in public areas.

Mounting Your Slasher to the Tractor
Before mounting the slasher to the tractor, ensure that the stabilizer bars and adjustable toplink are fitted to the tractor. It is essential that the slasher should be able to ride easily overobstacles. There must therefore, be no downward pressure from the tractor’s hydraulicsystem, and all “down pressure’ pins or other means of applying downward pressure, shouldbe removed. On many tractors the lift rods have an adjustable collar for exerting suchpressure. This collar must be moved to its lowest point so that both lift rods may ‘float” andallow the slasher to lift should it hit an obstacle.
Mounting must take place with the tractor and slasher on level ground. All directions given arefrom the rear of the slasher.

Ensure stabilizer bars orchains are fitted to tractor liftarms.
Slacken off stabilizer chainsor remove sway bars to allowthe fitting of lift arms to theclevis hitches.
Back the tractor up to theslasher until it is positionedrelative to the tractor PTOshaft and linkage points.
Connect the lift arms in thefollowing order:
1. Left hand lift arm to lefthand clevis hitch.
2. Right hand lift arm to righthand clevis hitch.
Adjust both lift arrns until theyare firm against the clevis hitchshoulders. Then secure eacharm with pins.
Adjust the tractor top link toapproximate length and attachto the top hitch on theheadstock section.
Secure with pin.
Connect the drive shaft to the tractor’s power take off,ensuring that the release pins on the clutch are located inthe PTO groove and the safety cover does not interferewith the tractor PTO guard.

Raise and lower the slasher to ensure that the driveshaft does not jam or become disengaged. If needed,the inner & outer tube, as well as the plastic cover ofthe drive shaft, may need shortening. If so, use ahacksaw to cut both the inner and outer tubes, to equallength. Do not overcut - cut off only a little at a time.Similarly,cut plastic cover to appropriate length.
Refit and re-test lifting arc.
Level the slasher by adjusting the right hand tractor liftrod so that the blade beam clearance from ground isequal across the width of the slasher when the weightof the slasher is supported on the three point linkage.
Lower the slasher onto the ground and adjust tractortop link until the front of the skids just clear the ground.
WARNINGBEFORE PROCEEDING TO OPERATE SLASHER, READ THE SAFETY PRECAUTIONS (at the front ofthis manual), AND THE INITIAL MAINTENANCE GUIDE (Page 6)
It is IMPORTANT to test that the two sections of thedrive shaft do not, at any position in the lifting arc,close completely up, or extend such that there is lessthan 15cm inner tube engaged.
Rear Height Control Wheel
The Height Control Wheel Kit is available as an option, and fits easily to the slasher to give a semimounted effect. When using the height control wheel, the side skids are adjusted so the they are off theground when at cutting height. This allows the slasher to be turned sharply and generally operate withoutthe need to lift on the tractor hydraulics. Slashing operations can be performed faster and more easily.
Fitting:1. Attach pivot bracket to rear hole in slasher body2. Remove pivot pin from wheel arm, and attach wheel arm to pivot lugs. Secure with pivot pin and
split pin.3. Grease castor block, wheel assembly with a lithium based grease before working.
Trimming slasher with height control wheel fitted.
To trim slasher, remove pins from height control bracket and allow wheel to float loose. Rotate bladebeam until one blade is in the forward position. Raise the slasher on the tractor hydraulics until the frontblade is at the required cutting height. Adjust the tractor top link until the body or skids are parallel to theground. With height control wheel on the ground, fit pins to nearest hole in downward position.Set Hydraulic stop, raise slasher, and remove and refitheight control pins in next hole down. Viewed from theside of the slasher, the body should be angled forwardto allow relief between cutting edge of blades.

Maintenance and Lubrication
1. Drive Shaft
The drive shaft and universal joints are probably the most vulnerable part of any power driven implement,and regular maintenance of the slasher drive shaft is essential to ensure adequate service life. Therecommended preventative maintenance outlined below will assist in achieving optimum life and minimizedown time.
Lubricate universal joints using a good quality multi purposelithium base grease of No 2 consistency (NL G2 rating). egCastrol LM.EP2-Mobil-BP-Shell. Ensure that grease exudesfrom X all four cups thus giving complete lubrication. It isadvisable to push and pull the shaft laterally in the directionopposite to every seal while applying lubricant, as this tendsto relieve the seal and assist the flow of the new grease.
Separate the two sections of the drive shaft. Clean and thenlubricate the sliding surface with graphite powder ormolybdenum disulphide grease. Seizure between thesesections will create considerable end thrust during lifting andlowering operations which may result in serious damage toeither the tractor PTO shaft assembly or the slasher. Whenworking in dusty conditions it is advisable to carry out thisprocedure TWICE DAILY.
Check the universal joints for wear. If movement is found inexcess of .4mm end play or.25mm radial movement, replacethe universal joint.
Lubricate quick release plunger with penetrating lubricant.
2. Gearbox
The gear box is pre-filled with Shell Alvania EP (LF) Grease 00.
3. Slip Clutch
The clutch springs must be adjusted so that the clutch will drive the slasher blades during normal operationand normal conditions - but upon the blades contacting with obstacles such as tree stumps or posts, theclutch should slip. This is to avoid stress or damage to the gearbox.
The clutch will initially be stiff, and may require adjusting after the first few hours of work.
To adjust clutch, turn each nut evenly until the clutch springs are coilbound. Then slacken each nut off two(2) complete turns.
The specific working conditions may require further adjustments of the nuts. If so, ensure that all nuts arereleased evenly.
In normal conditions, the temperature of the clutch should be no higher than the temperature of thegearbox. If the clutch becomes hotter than the gearbox, this indicates that clutch needs tightening. If theclutch is set too loosely, the clutch plates will slip excessively, generating considerable friction heat. Thissituation also causes excessive wear on the clutch plates, and erratic turning of the spindle and irregularwork. Therefore it is vital that the clutch is adjusted correctly.

Prior to intitial operation of slasher
1. Ensure that gearbox is adequately lubricated.2. Check clutch setting.
After initial two hours of work
1. Check that all bolts are tightened correctly.2. Check clutch setting.3. Check oil level of gear box. Top up if
necessary.
Daily maintenance (rninimum of every 8 hours)
1. Separate and lubricate the drive shaft, inaccordance with the steps outlined on previouspages.2. Grease universal joints, in accordance withthe directions on previous pages.3. Check the level of oil in the gearbox, and topup if necessary.4. Check the underside of the slasher body, inparticular the blades. Replace blades if there isvisible signs of damage or excessive wear.5. Ensure bolts are tightened securely on theblades and skids.6. Check clutch settings, and adjust ifnecessary.
Maintenance and Lubrication Guide
The following routine maintenance procedures are recommended, to ensure the efficientand safe operation of your slasher, as well as maximising the work life of the machine.
Weekly Maintenance
1.Perform all steps as per daily service. 2.Check andtighten all nuts and bolts on the slasher. 3.Clean awayany residue on the slasher, and spray a penetratinglubricant over all outer pins and bushes. 4.Afterapproximately every 50 hrs of work, check universaljoints for excessive wear.
After Every 250 Hours of Work
1.Inspect thoroughly the safety clutch, friction discs, anduniversal joints, and replace any worn parts.2.Complete full service, as per daily and weeklyprocedures. Pre-season InspectionPrior to commencing use of the slasher, particularlywhen the slasher has not been used for over a month,the clutch should be dismantled, and the friction discsinspected for wear and distortion.
To clean clutch facings, fit the slasher to tractor, andloosen clutch nuts until the springs are free. Lock therotor using a length of wood between the rotor and theslasher body. Start the tractor and idle approx. 800 rpm.Engage PTO allowing the clutch to slip sufficiently toclean clutch plates. Do not allow the clutch to overheat.Then stop tractor and reset the clutch as per clutchsetting.
