COMMENTS AND RECOMMENDTIONS
19.1 Engine performance test
i) The back-up torque of- the engine under natural ambient condition was reported to be
27.4 and 17.5 percent at full throttle and at setting recommend for fieid operation respectively.
ii) The maximum operating temperature of engine oil was observed as 128 0C 1C.It against the declared value of D5 is oh higher siOe. tt should be looked into.
19.2 Mechanical vibration
The amplitude of mechanical vibration of components marked as (8) in chapter 12 of this :repofi are observed on higher side. This calls for providing suitable “-.diul measures Ito dampen the vibration in order to improve the operational comfort and service life of 4t: various components &sub-assemblies.
Noise measurement The noise emitted by the machine at operator’s ear level was measured as 98.9 dB(A), :- which does not meet the requirements of IS: 15806-2008. This should be looked into.
19.4 Field performance test
During paddy harvesting, frequent chocking of unloading auger was observed. It
19.4.1 should be looked into.
19.5 Ease of operation and safety provision
i) It is recommended that the symbols as per the requirement of 15-6283 (part 2)-2007 may be provided.
ii) Drive safety arrangement (slip clutch) is not providecl at cutting platform auger, under shot conveyor, grain and tailing elevator. It is recommended io provide drive safety as it is essential requirement as per IS:15806-200g.
iii) First aid box is not provided on machine. It may be provided for safety.
iv) Stone trap is not provided before the threshing cylinder and concave, it may be provided lbr saf-ety.
v) The location of hand accelerator lever should preferably be at front or to the right side of operator as per IS: 8133:1983.
vii) Safety against accidental starl of engine as per IS: 8133:1983 is not provided. It should be looked into.
19.6 Service schedule of air cleaner is not specified. It MUST be specified for proper maintenance of machine.
19.7 On labelling plate of the combine SFC of engine is provided as < 30 kg/hm2. It may be provided in kg/kwh unit.
19.8 Hardness and chemical composition
19.g.1 Hardness & chemical composition of knife blade does not conform to the limits as specified in IS: 6025-1982.It should be looked into at regular production level.
19.8..Z Hardness of knife guard is not within the limit as specified in 15:6024-1983′ It should be looked into for improvement’
19.8.3 The carbon content of the knife back does not conform to the requirement of relevant IS code. It should be looked in to for improvement.
19.8.4 Equivalent Indian brand apPlicant.name & capacity of battery should be specified by
19.8.5 The equivalent Indian grades and brands of oil are not provided for guidance of user. provided. It MUST be
