A study was under taken to investigate the effect of blade type, cutting velocity and cross sectional area of stalks on cutting energy and cutting force required for cutting of black gram stalks. A laboratory test rig consisting of a pendulum type impact tester was designed and developed to measure the cutting energy. The bundled black gram stalks were fitted firmly in the stalk holder to simulate natural stand of stalk in the field. Two types of blades viz., smooth edge and serrated types were used for the present study. The experimental results showed that the cutting energy and cutting force requirement were increased as the cross sectional area of black gram stalks increased whereas these values were decreased as the cutting velocity increased for both type of blades. Serrated type blade required less cutting energy and cutting force as compared to that of smooth edge type blade at all diameter of stalks and cutting velocities.
