18.17 Salient observations:

18.17.1 Engine performance:

i) The backup torque of engine is 7.82 %, under natural ambient

condition.

ii) The maximum power was observed as 8.8 kW& 8.5 kW under

natural & high ambient condition respectively.

iii) The specific fuel consumption corresponding to maximum power was

recorded as 229 g/kWh against the declared value of 272 g/kWh.

iv) The specific fuel consumption corresponding to rated power was

observed as 229 g/kWh against the declared value of 272 g/kWh.

v) The maximum torque was recorded as 45.5 Nm against declared

value of 46.5 Nm under natural ambient condition.

18.17.2 Rotary shaft performance:

i) The maximum and rated rotary shaft power was observed as 7.1 kW.

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

speed was measured as 276 g/kWh against the declared value of

300g/kWh.

iii) The maximum equivalent rotary shaft torque was observed as 328.7

Nm against the declared value of 320 Nm.

18.17.3 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.

18.17.4 Noise measurement:

Max. Noise at operator’s ear level and by stander’s position was observed as 94 dB (A) and 81 dB (A) respectively. The noise

observed at operator's ear level is more than the limit specified by

IS 12239 (Part3) : 1988. The Sound Pressure Level is directly

influencing the Operator’s Health, Safety and Comfort; and therefore

warrants the corrective action.

18.17.5 Haulage test

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

gross mass of 1.25 ton.

18.17.5.2 Distance traveled per liter was observed 11.86 to 12.76 km.

18.17.5.3 Specific fuel consumption was observed 62.70 to 67.40 cc/km/t.

18.17.6 Wetland cultivation (Puddling test)

18.17.6.1 Puddling test was conducted with cage wheels and hatchet blades.

18.17.6.2 The maneuverability of power tiller during puddling test was found

satisfactory.

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

samples from engine sump, clutch assembly, gear box, chain case and

rotary shaft housing, no entry of mud and/water was observed.

18.17.7 Rotary blades:

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

operations was observed as 0.05 to 0.18 percent and 0.15 to 0.23

percent respectively.

ii) Carbon content of straight blade, Carbon and Silicon content of

hatchet blades do not conform to the IS 6690:1981 (Reaffirmed

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

iii) The dimensions of straight & hatchet blades conforms to the

requirement of IS 6690:1981 (Reaffirmed 2012).

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

requirement of IS 6690:1981 (reaffirmed 2012).

18.17.8 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.

18.17.9 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.
