The manual pedal paddy thresher uses a stainless steel drum and a wooden pedal assembly, driven by foot or by a gasoline engine — designed for areas with no or unstable power, it runs reliably in harsh conditions. Rice ears are fed between the drum and the concave, the pegs knock the grain loose, grain falls through the screen into the collecting box and straw leaves at the side. Bolted folded-sheet construction keeps it light and easy to dismantle.
