Abstract: The experimental threshing unit was comprised of the corn ears belt-feeder with the length of 10 m and width of 0.8 m, and the tangential threshing cylinder with 10 rasp bars with the diameter of 0.8 m and width of 0.8 m, which was enveloped by the grate-bar type concave at the angle of 130º. The studies have been designed and manufactured five different forms of concave bars, which mounted in the variable radius concave. Rasp bars of concave have a positive effect on grain damage during threshing, grain separa-tion through the concave (increases grain separation intensity through concave) and threshing loss. Studies reasonable that the corn ears threshing rational to use L = 20 mm width and the surfa-ce angle α = 23° rasp bars of variable radius concave. Then threshing grain losses are minimal (0.03 ± 0.02%), while the injured cereal grain damage does not exceed 4%
