Natural disasters frequently compel farmers to lose their crops because they lack the customary old design of threshing mechanism. looking into every area of post-harvest losses and finding ways to make life easier for farmers, especially small farmers. A power-operated paddy thresher Mk-I was created, and after some modifications, such as the addition of rocking wheels for transportation and a poly sheet cover for the Mk-I, a paddy thresher Mk-II was created, and its operating parameters were discovered to be more similar to those of the standard one. This paddy thresher included a mechanism for winnowing as well. The performance evaluation was carried out on Sri Ram, 6444 and Brevant of paddy varieties available locally. The paddy thresher Mk-I had the threshing efficiency, cleaning efficiency, percentage of un-threshed grain and threshing input capacity as 90.03 %, 95.94 %, 9.67 %, and 1145.93 kg/h respectively. While the paddy thresher Mk-II had the threshing efficiency, cleaning efficiency, percentage of un-threshed grain and threshing input capacity as 94.05%, 95.70 %, 5.95 % and 970.33 kg/h respectively.
