The Jima drum replaceable multi-crop thresher which was produced at Jima agricultural engineering research center was evaluated in Fedis agricultural research center for threshing performance of the crops wheat and barley. During evaluation the basic variables that given-attention were feed rates (kg/min), machine speeds (rpm) and crop types. The performance evaluation was done for wheat and barley crops at their average temperature 21oC, average moisture content 12.25 % and at constant inlet 20mm, central-beneath 50mm and out-let 20mm drum-concave clearance of the machine. The results obtained were threshing efficiency varied in the range of 99.03% to 99.82% for wheat crop and 97.10% to 100% for barley. Its output capacity was 2.25 to 2.5qt/h and 2.2 to 2.86 qt/h for wheat and barley respectively.
