The rotary cutting mechanism was developed in Department of Farm Power and Machinery. The rotary cutting mechanism performs single operation i.e. collection of sorghum cobs with collection unit. Electric drive system is major source to operate electric motor, belt, pulleys etc. The laboratory test of rotary cutting mechanism held at Dr. PDKV, Akola for its performance. Rotary cutting mechanisms operated with seven different rpm of main shaft i.e. 290, 319, 363, 392, 435, 474 and 535 rpm. The cutting efficiency of rotary cutting mechanism ranges from 92 to 100 percent at 474 to 535 rpm of main shaft. The collection efficiency of mechanism increases from 290 rpm to 474 rpm and suddenly decreases at 535 rpm. The collection efficiency of collection unit was 76.47 to 97.20 per cent at 290 to 474 rpm of main shaft. Maximum collection efficiency was found to be 97.20 per cent at 474 rpm respectively.
