6.4 Salient Observations:

6.4.1 Laboratory tests:

6.4.1.1 PTO Performance: i) The maximum power was recorded as 30.3 & 29.1 kW in case of previous &

present sample respectively against the declaration of 28.7 kW, which is within the tolerance limit of IS: 12207-2019.

ii) The specific fuel consumption corresponding to maximum power in case of previous and present sample was measured as 240 & 259 g/kWh respectively against the declaration of 236 g/kWh, which meets the requirement of IS: 12207-2019 with regard to tolerance.

iii) The maximum equivalent crankshaft torque was recorded as 186.5 & 178.1 N-m in case of previous & present sample respectively against the declaration of 171.6 N-m, which is within the tolerance limit of IS: 12207-2019.

iv) The backup torque is 18.6 %.

v) The drop in maximum PTO power was observed as 6.2 % between natural and high ambient condition, which is considered on higher side. This should be looked into for necessary corrective action.

vi) The high idle speed of the engine was recorded as 2204 rpm against the rated engine speed on 1850 rpm. The percentage fly-up is recorded as 19.1%, which is considered to be very high. This should be re-examined and setting of fuel injection pump should be done accordingly.

6.4.1.2 Three point linkage:

i) The lateral distance from lower hitch point to centre line of tractor does not meets the requirement of IS: 4468 (Part-1)-1997 (Reaffirmed in October 2017). This should be looked into for necessary corrective action.

ii) The diameter of pin hole of upper hitch point and lower link hitch point do not meets the requirement of IS: 4468 (Part-1)-1997 (Reaffirmed in October 2017). This should be looked into for necessary corrective action.

iii) Some of the parameters of three point linkage conforms to Cat-I and some of them conforms to Cat-II keeping in view the spirit of standardization necessary improvements may be incorporated.

6.4.1.3 Operator’s seat : i) Longitudinal distance form seat index point to centre of steering control wheel

does not meet the requirements of IS: 12343-1998 (Reaffirmed in 2014) ii) Vertical distance form seat index point to foot rest wheel does not meet the

requirements of IS: 12343-1998 (Reaffirmed in 2014)

6.5 Maintenance / Service problems:

No noticeable maintenance or service problems, observed during the test.

6.6 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) There should be provision for spark arresting device in exhaust system. ii) The fuel shut-off knob should remain in stop position. iii) The working clearance around position & draft control lever should be provided

as per relevant standard. iv) Vertical distance form Seat Index Point to centre of clutch pedal should meet the

minimum requirement as per relevant standard. v) The width of foot step may be provided as per the requirement of per relevant

standard. vi) Vertical retainer should be provided on both side of clutch pedal. vii) PTO shaft master shield should be provided to avoid the accident. viii) There should be provision of differential lock in tractor.
