18.16 Salient Observations:

18.16.1 Engine Performance:

i) The backup torque of engine is 8.04 %, under natural ambient

condition.

ii) The maximum power was observed as 9.8 & 9.5 kW under natural &

high ambient condition respectively.

iii) The specific fuel consumption corresponding to maximum and rated

power was recorded as 227 & 226 g/kWh against the declared value

of 294 g/kWh.

iii) The maximum torque was recorded as 50.4 Nm against declared

value of 55.0 Nm under natural ambient condition.

18.16.2 Rotary shaft performance:

i) The maximum and rated rotary shaft power was measured as 8.1 kW.

ii) The specific fuel consumption corresponding to power at rated engine

speed was measured as 261 g/kWh against the declared value of 324

g/kWh.

iii) The maximum equivalent rotary shaft torque was observed as 447.8

Nm against the declared value of 460 Nm.

18.16.3 Mechanical Vibration:

The amplitude of mechanical vibration on most of controls /

measuring points of the power tiller exceeded the limit of 100 micron.

The mechanical vibration is directly concerned with Operator’s Health, Safety and Comfort; apart from the useful life of the

machine’s components. In view of the above, this should be taken

care for corrective action.

18.16.4 Noise measurement:

Max. Noise at operator’s ear level and by stander’s position was observed as 96 dB(A) and 79 dB(A). The noise observed at operator's

ear level is more than the limit specified by IS12239 (Part3) : 1988.

The Sound Pressure Level is directly influencing the Operator’s Health, Safety and Comfort; and therefore warrants the corrective

action.

18.16.5 Haulage test

18.16.5.1 The power tiller was recommended for haulage test with a trailer of

gross mass of 1.5 tonne.

18.16.5.2 Distance traveled per litre was observed 13.39 to 13.64 km.

18.16.5.3 Specific fuel consumption was observed 48.87 to 49.78 cc/km/t.

18.16.6 Puddling test

18.18.6.1 Puddling test was conducted with cage wheels and with hatchet blade.

18.16.6.2 The maneuverability of power tiller during puddling test was found

satisfactory.

18.16.6.3 On partial dismantling of the power tiller and inspection of the oil

samples from engine, crankcase, transmission case and rotary chain

case, no entry of mud and/water was observed in the rotary shaft

bearing cap.

18.16.7 Rotary blades:

i) The hourly rate of wear of blades for dry land and wet land

operations was observed as 0.10 to 0.35 percent and 0.08 to 0.19

percent respectively.

ii) Carbon and silicon content of straight blades and carbon, silicon and

manganese content of hatchet blades do not conform to IS 6690:1981

(Reaffirmed 2012). This should be looked into for corrective action.

iii) The dimensions of the blades conforms to IS 6690:1981 (Reaffirmed

2012).

iv) The hardness of straight & hatchet blades meet the requirement of IS

6690:1981 (reaffirmed 2012).

18.16.8 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.

18.16.9 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.

18.16.10 Provision of spark arresting device may be considered for

incorporation in the exhaust system.

18.16.11 Two metallic labeling plates, one is screwed on timing cover & other

plate pasted on RHS of tool bar. Whereas provided metallic plates

should be as per IS 10273:1987.

18.16.12 It is recommended that the tyre should have the “Marking” as per clause 8 of IS:13154-1991.

18.16.13 The handle grip does not meet the requirement of IS: 11858 – 1986.

This may be looked into for compliance.
