17.4 Salient Observations:
17.4.1 Laboratory tests:
17.4.1.1 PTO Performance:
i) The backup torque is 22.9 %.
ii) The specific fuel consumption corresponding to maximum power was recorded
as 245 g/kWh, against the declaration of 258 g/kWh, which meet the requirement of IS: 12207-2008 with regard to tolerance.
iii) The defect reported in chapter No. 15 of this report has been rectified by the manufacturer at the design/production level. No further breakdown/defect observed during course of testing.
It is therefore recommended that, the modified water pump mounting
bracket (Part No. P219409B) as given in Annexure-II should be used in
regular production of the tractor.
17.4.1.2 Mechanical Vibration:
The amplitude of mechanical vibration on various assemblies marked as (*) in Chapter-9 of this test report is on higher side, especially at the steering control wheel and foot rests. This calls for dampening down of vibrations to improve the operational comfort and service life of components.
17.4.1.3 Three point linkage:
Lateral distance from lower hitch point to centre line of tractor does not meet the requirements of IS 4468: 1997. It should be looked into for compliance.
17.4.1.4 Operator’s Seat:
The longitudinal distance from seat index point to centre of steering control wheel does not meet the requirements of IS: 12343-1999. It should be looked into for compliance.
17.4.2 Field Performance:
17.4.2.1 Wet land cultivation (Puddling Operation): No ingress of mud/or water was observed during wetland cultivation. Hence the
tractor meets the requirements for wet land cultivation as per IS: 11082-1984 and found suitable for wetland cultivation
17.5 Recommendation with regard to safety on tractor:
The following requirements, inter alia, may be considered for incorporation on the tractor:
i) Provision for spark arresting device in exhaust system.

CENTRAL FARM MACHINERY TRAINING & TESTING INSTITUTE - BUDNI Page 9 of 13
17.6 Maintenance / Service Problems:
No noticeable maintenance or service problem was observed during the test.
17.7 Adequacy of Literature supplied with machine:
The following literature was supplied with the tractor for reference during the test:
i) Operator’s Manual
ii) Spare parts catalogue
17.7.1 Therefore it is recommended that, the service/workshop manual for this tractor model should be brought out as per IS: 8132-1999 (Reaffirmed in march, 2009) for the guidance of users and service personnel in national as well as other regional languages.
