15.3 Salient Observations: 15.3.1 Laboratory tests: 15.3.1.1 PTO Performance Test:

i) The maximum PTO power was recorded as 25.5 kW against the declaration of 26.0

kW, which meets the requirement of IS: 12207-2019 with regard to tolerance limit.

ii) The rated PTO power was recorded as 25.1 kW against the declaration of 26.0 kW,

which meets the requirement of IS: 12207-2019 with regard to tolerance limit.

iii) The specific fuel consumption corresponding to maximum power was recorded as 245

g/kWh against the declaration of 265 g/kWh , which meets the requirement of IS:

12207-2019 with regard to tolerance limit.

iv) The maximum equivalent crankshaft torque was recorded as 158.4 N-m against the

declaration of 153.0 N-m, which meets the requirement of IS: 12207-2019 with regard

to tolerance limit.

v) The backup torque is 32.0 %, which meets the requirement of IS: 12207-2019 with

regard to tolerance limit.

vi) The drop in maximum PTO Power of 7.1% was recorded between natural and high

ambient condition, which is on higher side. Therefore, this should be looked into for

necessary corrective action.

15.3.1.2 Drawbar performance test:

i) The maximum drawbar power under unballast condition in case of previous and present sample was recorded as 24.7 kW & 21.0 kW respectively. The drawbar power recorded in case of present sample is 17.6% lower than the previous test sample.

ii) The maximum drawbar pull corresponding to 15% wheel slip under unballasted condition in case of previous and present sample was recorded as 15.74 kN & 14.11 kN respectively. The maximum drawbar pull recorded in case of present sample is 11.6% lower than the previous test sample.

From the above, it indicate that the overall drawbar performance of the tractor was found deteriorated and this should be looked into.

iii) During ten hour drawbar performance test, creeping of LHS & RHS rear tyre over the rims was recorded as 20 mm & 30 mm respectively. This should be looked into for necessary corrective action.

15.3.1.3 Hydraulic performance test: The moment about rear axle with standard frame was computed as 16.26 kN-m, whereas,

the moment about front axle was computed as 14.49 kN-m under unballasted condition. The moment about rear axle with standard frame is on higher side as compared to the moment about front axle. Therefore, it is recommended that the lifting capacity of the hydraulic system may be reduced suitably or ballast mass recommendation may be reviewed to avoid the front lifting of the tractor.

15.3.1.4 Mechanical Vibration:

The amplitude of mechanical vibration on various assemblies marked as (*) in Chapter – 9 of this test report is on higher side. This calls for dampening down of vibrations especially on steering control wheel to improve the operational comfort and service life of components.

15.3.1.5 Specifications of three point linkage: i) The parameter lateral distance from lower hitch pint to centre line of tractor does not

meet the requirement of IS: 4468 (Part-1) -1979 (Reaffirmed 2014). This should be looked into for necessary corrective action.

ii) Some of the parameters of three point linkage conform to Cat. I and some of them conform to Cat.II. Keeping in view the spirit of standardization, necessary improvement may be incorporated.

15.4 Maintenance / Service Problems:

No noticeable maintenance / service problem was observed during the test.

15.5 Recommendation with regard to safety on tractor: The following requirements, inter alia, may be considered for incorporation on the tractor:

i) Length of seat should be provided as per relevant standard. ii) Width of foot step should be provided as per relevant standard. iii) Inclination of back rest should be provided as per relevant standard. iv) Accidental start safety switch should be provided. v) The Fuel shut-off knob should remain in “STOP” position. This should be re- designed/

improved to enhance the safety. vi) Differential lock should be provided. vii) There should be provision for spark arresting device in exhaust system. viii) Provision of master shield in power take-off. ix) Provision for easy mounting and dismounting of operator should be provided. x) The working clearance between the mudguard and draft control lever should be

provided as per relevant standard.

15.6 Adequacy of Literature supplied with machine: 15.6.1 The following literature was supplied with the tractor for reference during the test.

i) Operator‟s manual for Sonalika International DI-35 SM, DI-35 RX, DI-42 RX, DI-745 III RX, DI-45 RX TURBO, DI-52 RX, DI-55 RX, DI-55 RX TURBO, DI-60 RX MM, DI-60 RX MM SUPER, DI-60 RX TURBO, DI-750 III RX 4-CYL & DI-60 RX 4-CYL tractor models.

ii) Spare part‟s catalogue for Sonalika International DI-35 SM, DI-35 RX, DI-42 RX, DI-745 III RX, DI-45 RX TURBO, DI-52 RX, DI-55 RX, DI-55 RX TURBO, DI-60 RX MM, DI-60 RX MM SUPER, DI-60 RX TURBO, DI-750 III RX 4-CYL & DI-60 RX 4-CYL tractor models.

iii) Service manual (Part-I & II) for Sonalika International DI-35 SM, DI-35 RX, DI-42 RX, DI-745 III RX, DI-45 RX TURBO, DI-52 RX, DI-55 RX, DI-55 RX TURBO, DI-60 RX MM, DI-60 RX MM SUPER, DI-60 RX TURBO, DI-750 III RX 4-CYL & DI-60 RX 4-CYL tractor models.

15.6.2 The supplied literature was found in adequate as it does not cover the following

information. Therefore, it is recommended that the relevant literature may be updated by incorporating the following information:

i) Information related to PTO, Drawbar and hydraulic performance of the tractor such as Maximum torque, backup torque, Specific fuel consumption, Maximum drawbar Power & pull, hydraulic pump discharge rate, hydraulic power & lifting Capacities etc. should be included in the technical specification of the tractor for the guidance of the user‟s.

ii) The Maintenance schedule for transmission oil, rear axle & final drive oil, hydraulic & brake oil and air cleaner oil given in operator‟s manual does not match with specification submitted by applicant.

iii) List of matching implements, trailers and other farming equipments. iv) List of Standard fitments. v) List of accessories & supplied with the tractor.

15.6.3 It is therefore, recommended that following literature may 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 regional languages for this model of tractor.
