The Research was carried out in the laboratory of Farm Machinery and Power Collage of Technology, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, for general testing of multi crop thresher on wheat crop, RAMSONS IMPEX made thresher.
The testing was carried out as per the IS: 6284:1985 test codes. The various tests i.e. Checking of Specifications, Checking for Material of Construction, Visual Observations and Provisions of Adjustments, Checking of Safety Provision and Pre-test observation which comes under the general test were carried out. It is observed that during the pre-test observation the parameters like grain crop ratio, moisture content of straw and grain, shaft speed…etc. were found within the specific limits as per standard.
All the specifications were found to be equal with the specifications provided by manufacturer. The performance of the thresher was found to be satisfactory, but still there is need of upgradation in some parameters like safety cover of prime mover and transmission, feed rate adjustment, minimize knocking and rattling sound, slippage of belt, repair of transport wheel, frequent clogging, rise in bearing temperature and the provision of hitching arrangement. There is also need for checking the overall performance during short and long run test.
