The Paddy thresher is designed for manual threshing of rice. It consists of a loop type threshing drum which is supported on a frame. It contains two cast iron gears which quadruples the speed obtained from treadle movement of the cylinder to about 400 rpm. Paddy threshing is done by holding the paddy stalks with grain against the death of the revolving cylinder.
