The purpose is to reduce the energy costs of soil tillage by developing more accurate methods for assessing the effectiveness of surface-plane and space-deep interaction of the needle with the soil. It is noted that the result of the interaction of the round needle of rotary harrow with the soil, there is a hole of regular shape with an ellipse at the base. The change in the semi-axis of the ellipse formed at the soil-air interface is analyzed. The developed method improves the accuracy of forecasting and evaluating the effectiveness of the rotary harrow needle interaction with the ground. The method creates the prerequisites for improving the quality and energy indicators of the technological processes of soil treatment with rotary harrows

INVESTIGATION OF THE GRAIN SEPARATION PROCESS IN THE THREE-DRUM THRESHING-SEPARATING DEVICE OF A COMBINE HARVESTER
The purpose is improving the efficiency of the technological process of threshing and separating the grain pile in a multidrum threshing-separating device due to the substantiation of the technological modes of the work of threshing drums. The influence of technological parameters of the three-drum threshing-separating device of a grain-harvesting combine on the process of grain separation has been studied experimentally. Models of the grain separation process are obtained depending on the speed of rotation of the drums and the supply of technological material for threshing, based on the results of the experimental research. modeling the process of grain separation depending on the speed of rotation of the drums and the supply of technological material for threshing allows to determine the quantity and quality of the mass that each of the three drums separately threshed.
