This paper deals with the development and testing of a pedal operated finger millet thresher. The prevalent millet threshing method like beating with sticks, rubbing and trampling finger-heads under bullock’s feet or men feet are tedious and labour and time consuming. Pedaling is the most efficient way of utilizing power from human muscles. Keeping this thing in mind pedal operated thresher for minor millets with spike-tooth type threshing cylinder was developed and tested. The physical properties of finger millet grain such as moisture content, bulk density, straw grain ratio, size, and angle of repose was studied. A finger millet thresher of feeding capacity 43.37 kg/h was designed on the basis of these physical properties. The thresher was tested with a view to increasing the threshing efficiency and reducing the cost of threshing in comparison with traditional method of threshing of finger millet. It was observed that the maximum threshing efficiency of 68% can be achieved by threshing the finger millet crop at 11% mc at the peripheral speed of 11.18m/s (850 rev/min), when the concave clearance is 7mm. The thresher was tested at three different speeds for its performance in terms of threshing and cleaning efficiency, visible damage, germination percentage, and sieve losses.
