Summary. The article deals wit the results of experimental research on "Elita" and "G-12" stem corn threshing process using a one drum threshing machine. It has been determined that by cutting the corn directly with unreadjusted combine harvester, it is necessary to leave a stubble of about 0,6 meter hight. The mass of the harvested materials falling into the threshing machine decreases. Allowable mass flow of the supplied maize "Elita" is 2,5 kg/sm (stubble height l=200 mm) and of maize "G-12" (stubble height l = 500 mm) - 7 kg/sm. The optimum threshing drum rotation frequency is 600 min-1 (correspondingly to 19 m/s). The gap between the drum and concave can alternate from 24-24 mm to 32-32 mm.
Key words: thresh vehicle, corn, optimum parameters
