The subject of the study are the qualitative indicators of the work of the rotary tiller ripping-separating machine. In the field conditions, the influence of the rotation frequency of the rotor of the tillage ripping-separating machine on the physical and mechanical properties of the soil after its treatment at a constant value of its kinematic parameter, the speed of movement of the aggregate, and the depth of processing was determined experimentally. The qualitative performance of the machine was evaluated by the coefficient of soil structure of the lower and upper layers. The first layer is 0... 0.5 cm deep (the surface layer), the second layer is at a depth of 0.5 cm from the depth of the treatment to the bottom of the furrow (bottom layer). The object of the study is a layer of soil processed by the soil cultivating ripping-separating machine. As a result of processing, its stratification takes place. The initial information for the study substantiation was obtained by analyzing the literature sources. It is determined that with the growth rate of the rotor the coefficient of soil structure increases, and the dynamics of the soil texture coefficient change with a linear change in the rotor speed of the experimental machine is the same. The actuality is that the use of an active working organ (rotor) on the combined machine allows for a high quality of soil treatment in one pass of the unit, and the interaction of active-passive working organs allows improving the quality of crumbling of the soil layer.
