An axial flow peanut thresher was designed, constructed and tested. Due to its potential use by small farmers with less than 2 ha farms, it was of simple design, easy to fabricate and of low cost. The threshing cylinder was 120 cm long and 15 cm in diam., with paddle shaped combing teeth projecting 9 cm from the cylinder's surface and arranged in the form of a helix. The cylinder rotated in a concave which comprised of 10 mm round bars, spaced 2.5 cm apart.
