18.16 Salient Observations:

18.16.1 Engine Performance:

i) The backup torque of engine is 12.16 %, under natural ambient

condition.

ii) The maximum power was observed as 9.1 kW & 8.9 kW under

natural & high ambient condition respectively.

iii) The specific fuel consumption corresponding to maximum power was

recorded as 239 g/kWh against the declared value of 285 g/kWh.

iv) The specific fuel consumption corresponding to rated power was

observed as 234 g/kWh against the declared value of 270 g/kWh.

v) The maximum torque was recorded as 47.58 Nm against declared

value of 44.0 Nm under natural ambient condition.

18.16.2 Rotary shaft performance:

i) The maximum and rated rotary shaft power was measured as 7.5 &

7.4 kW respectively.

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

speed was measured as 265 g/kWh against the declared value of 315

g/kWh.

iii) The maximum equivalent rotary shaft torque was observed as 367.2

Nm against the declared value of 380 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 95 dB(A) and 82 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 1.0 tonne.

18.16.5.2 Distance traveled per litre was observed 12.01 to 12.15km.

18.16.5.3 Specific fuel consumption was observed 82.29 to 83.26 cc/km/t.

18.16.6 Puddling test

18.16.6.1 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 0.13 to 0.31 percent and 0.16 to 0.37

percent respectively.

ii) Manganese & silicon content of straight blade, Carbon and silicon

contents of hatchet blades do not conform to IS 6690:1981

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

iii) The dimensions of straight blades conform to the requirement of IS

6690:1981 (Reaffirmed 2012), whereas dimensions do not conform

for hatchet blade.

iv) The hardness of straight and hatchet of blades conforms the

requirement of IS 6690:1981 (reaffirmed 2012). This should be

looked into for corrective action.

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 riveted on timing cover & other

plate is riveted on tool bar. Whereas provided metallic plates should

be as per IS 10273:1987.
