For wheat, threshing and cleaning efficiency were respectively 99.84% and 99%, at threshing cylinder speed of 19.3 m/s. Total grain losses, broken grain output capacity and power consumption were 0.82%, 0.35%, 276 kg/h and 3.4 kW, respectively. It saved 26-39% labour and operating time and 22% in cost of operation. CIAE multi-crop plot thresher consisted of spike tooth cylinder of 250 mm diameter and 250 mm length suitable for precision threshing of wheat. The results indicated 99.3% threshing efficiency, 93.4% cleaning efficiency and 29.5 kg/h output capacity. At 1100 rpm broken grain, grain recovery and power consumption were 0.02%, 99.83% and 0.65 kW, respectively.
