16.13 Salient Observations:
16.13.1 Engine Performance:
i) The backup torque is 2.19% only, which is very low and needs to be
improved.
ii) The maximum brake horse power of the engine at 2000 rpm was
observed as 6.7 kW during maximum power two hours test.
iii) The specific fuel consumption corresponding to max power was
recorded as 295 g/kWh against declared value of 270 g/kWh. This
should be looked into. iv) The pressure release setting and minimum permissible pressure of
lube oil pump is specified as 215 kPa and 2.5 kPa respectively. This
should be looked into.
16.13.2
Rotary shaft performance:
i) The maximum rotary shaft power was measured as 5.7 kW.
ii) The rotary power at rated engine speed was measured as 5.7 kW.
16.13.3
Drawbar performance test:
i) The power tiller developed 4.9 kW Power during drawbar
performance test in H1 gear corresponding to 15% wheel slip.

16.13.4 Mechanical Vibration:
The amplitude of mechanical vibration on maximum controls /
measuring points of the power tiller exceeded the limit of 100 micron.
It should be dampened down to improve operational comfort and life
of the components.
16.13.5
Noise measurement:
Max. Noise at operator’s ear level and by stander’s position was
observed as 94 dB (A) and 82 dB (A). The noise observed at
operator’s ear level is more than the limit specified by IS: 12239
(Part 3) – 1988. This should be looked into.
16.13.6
Haulage test
16.13.6.1 The power tiller was recommended for haulage test with a trailer of
gross mass of 1.0 tonne
16.13.6.2 Distance traveled per litre was observed 12.19 to 12.49 km.
16.13.6.3 Specific fuel consumption was observed 80.06 to 82.03 cc/km/ton
16.13.7 The chemical composition of the blades does not conform, in full, to IS: 6690-1981.
16.13.8 The Hardness of the blades does not conform, in full, to IS: 6690-
1981.
16.13.9 As per IS: 12239 (Part 3) – 1988, “maximum safe speed” with trailer
is required to be specified by the manufacturer. Necessary action may
be taken in this regard.
16.13.10 As per IS: 12239 (Part 3) – 1988, balancing mass to be added to
achieve correct weight balance of the power tiller with various
attachments should be recommended by the manufacturer in the operator manual. This may be examined for compliance.
16.13.11 Provision of spark arresting device may be considered for
incorporation in the exhaust system.
16.14
General observation:
The handle grip does not meet the requirement of IS: 11858 – 1986.
This may be looked into for compliance.
16.15
Maintenance / Service problems:
No noticeable maintenance / service problem was observed during the
test. Provision for draining of sediments/water in fuel tank may be
provided to check contamination/impurities in fuel.
