Surface treatment includes soil presowing, steam, inter-row cultivation and is performed by cultivators or combined u machines. The applied working organs carry out one-way free action on the soil. This leads to a displacement, discarding of soil sections in one or different directions, depending on the shape of the flat surface of the working organ. The resistance associated with discarding the soil, giving kinetic energy is in a quadratic dependence on the speed S of the working movement. Therefore, most often there is a restriction not exceeding 12 km/h, thereby restraining ^ productivity growth. The absence of counteraction does not allow providing a high degree of crumbling and leveling of the soil surface. That is why when surface processing of soil in combination with soil cultivating paws discs, harrows, equalizers, rollers of different modifications on cultivators are installed. They carry out soil re-grinding and О leveling the surface. However, this significantly increases the specific material consumption of soil cultivating units. ^ It for some of them reaches 300-400 kg/m. This is an additional material and financial costs, in addition, there is a О reconsolidation of the soil, deterioration of conditions for the growth and development of plants. It is necessary to 1 analyze and test different ways of affecting the soil: multidirectional, constrained and concentrated. It has been established that in order to improve the quality of the surface treatment of soil, it is necessary to use a multidirectional, constrained or concentrated effect, using innovative technical solutions of soil cultivating working organs. As a result, stabilization of the depth of processing is ensured, removal of moist soil on the day surface is excluded, productivity is increased and energy costs are reduced.
