The technological indices of the efficiency of grain combine harvesteroperation include the quality of the ob-tained grain mixture and the amount of grain loss. The hu-man factor has a great influence on these indices which can be minimized by automating the control of the combine harvestercleaning. We have proposed a design of such a device including a fan drive from an asynchronous electric motor with afrequency converter, servo controls for adjust-ing the angles of the upper and lower shutters, an acoustic grain loss sensor that allows feedback in the control sys-tem and the process controller. As a result, the effect of the internal combustion engine ofthe combine on the shaft rotation frequency will be reduced; there will be no need to use the DC electric drive or a fan mechanical drive; it will be possible to automatically adjust the angle of inclination of the shutters with an accuracy of 0.1°; therewill be the possibility of constructing a cleaning system control algo-rithm based on neural networks. The use of this device will improve the quality of harvesting, reduce grain losses and reduce the amount of impurities in the combine hopper
