Improving the working body for primary soil cultivation

The paper presents a universal working tool that allows both moldboard-less soil cultivation and plowing with layer turnover. A design of a plow-ripper-slitter has been developed, the novelty of which is protected by a patent of the Russian Federation. The article analyzes the influence of the location of the moldboard-rippers on the directional stability of the machine-tractor unit. The authors have identified the possibility of stabilizing rectilinear movement due to the console arrangement of the slitters on the edge of the frame of the working tool. The study determines the limitations of stable operation of a machine-tractor unit with a plow- ripper-slitter. The dependence of the traction resistance of the slitter on the depth of processing is obtained. As a result, recommendations were given on the depth of soil cultivation for slitter of different widths.
