A pendulum impact cutting test-rig and a cutting force measurement system composed of a cantilever weigh sensor and a high speed analog acquisition card were developed. Then cutting mechanical property experiments of super rice stalk were carried out. According to the measuring cutting force, the cutting power consumption of different super rice stalk were calculated, and the influence of cutting speed, cutting position and parting cutter on the cutting force and consumption were analyzed. The results indicated slight decreasing tendency of cutting force with the increasing of cutting position. The peak cutting force and the cutting power consumption nearly linear increased with the increasing of cutting sectional area, but both decreased gradually with the increasing of cutting speed. The peak cutting force of different single super rice stalks could reach 24~32N. 
