Salient Observations:
5.2.1
Laboratory tests:
5.2.1.1
PTO Performance: i) The backup torque is 35.8 %. ii) The specific fuel consumption corresponding to maximum Power was measured as 290 g/kWh against the declaration of 285 g/kWh and meets the requirements of IS: 12207-2008 with regard to tolerance.
5.3
iii)
The percentage drop in maximum power during natural ambient and high ambient condition was observed as 8.7 %, which was considered on higher side. This should be looked into for necessary corrective action.
iv)
The maximum PTO power during normal ambient condition was observed at Engine speed of 2300 RPM whereas the maximum PTO power during high ambient condition was observed at Engine speed of 1948 RPM . This observation indicates that the performance of tractor during high ambient condition is not normal. This should be examined and improved.
v)
The PTO power at Rated engine speed during Normal and High ambient condition was observed as 44.6 and 38.2 kW respectively. There is significant difference (14.24 %) in the power observed during Normal and High ambient condition. This should be examined and improved.
Vi)
After the maximum torque speed, the engine is having tendency of sudden drop and cope up in engine speed (30-40 RPM) each time when further loading is done.
Maintenance / Service problems: No noticeable maintenance and service problems was observed during the test..
5.4
Recommendation with regard to safety on tractor: The following requirements, inter-alia, may be considered for incorporation on the tractor as per relevant Indian Standards: i) ii) iii) iv)
Provision of spark arresting device in exhaust system. “Minimum cautionary notice” as per clause 11.2 of IS:12239 (part-2)-1999 Provision of Master shield for PTO shaft Provision of front tow hook.
