Abstract:
A large number of farmers thresh paddy crop by hand or by a walk on it under feet of animals. Now a day’s number of progressive farmers are using pedal-operated or hold on type threshers, which does not have a cleaning facility. In the present study, the performance of the tractor-operated winnower was evaluated at three different winnower fan rpm, which were 786, 918 and 1049rpmall the parts of were connected with the help of tachometer circuit diagram. From the results, found that optimum cleaning efficiency of 96 percent at winnower rpm of 918. Hence, tractor operated winnower can be operated at 918 rpm for high cleaning efficiency and winnower hopper can be adjusted at a distance of 60 cm from winnower fan axis to provide an optimum air velocity to the grain.
