RESULTS OF STUDIES OF THE COMBINED WORKING UNITS’ INDICATORS OF SOIL CULTIVATION IMPLEMENT

The main direction of development of machines for minimal soil cultivation is the intensification of the technological process by combining several operations. In this case, the most appropriate way to increase productivity, reduce energy consumption and improve the quality of work should be considered the use of the sliding cutting effect in them, as well as the fulfillment of the condition for guaranteed movement of the soil layer relative to their working surface. The article presents the results of studies of combined working units indicators of a tillage. Based on the results of laboratory studies and field experiments, the degree of soil crumbling, the leveling of field surface, the range of soil discarding, etc. have been determined. The production tests of combined tillage tools with the proposed working units confirmed the conclusions that it significantly improves the quality of minimal tillage and ensures a higher crop yield on average by 13.5% (compared to the existing unit KPS-4 + PP).
