Abstract: In order to analyze and investigate the threshing process is necessary to capture the dynamic processes in the threshing machine, e.g. threshed material velocity on concave surface, forces acting on concave, threshing cylinder speed, power demand, grain separation through the concave and other parameters. After modernization of the stationary threshing rig, it became possible to simultaneously measure forces operating on rear transverse bar of concave, threshing cylinder speed, and mass separated through concave in small time intervals (every 0.03 s). Experimental results shown, that the raise of corn ears feedrate influences the average threshing cylinder speed, which is reduced from 3.5% (at 4 kg s"1) to 12.7% (12 kg-s"1). During the feedrate peak values, threshing cylinder speed drop was up to 19.2%. The average force acting on the rear transverse bar of concave, during threshing process, increases more than 3 times, from 42.5±24.2 N (4 kg-s"1) to 129.7±28.6 N (12 kg-s1)
