The work is devoted to the issue of improving the quality of cultivating of root-bearing soil layer and optimizing its agrotechnological properties. Improving the quality of cultivation is due to the application of soil cultivating tools equipped with disk-knife working bodies. They are provided theoretical and experimental study of the work of the disk-knife working body, and it is substantiated its rational parameters. The basis of the substantiation of the parameters of the cultivating tool is the original analytical model, which reflects the process of interaction of the working body with the soil. To study the performance of the process, on the basis of kinematic equations of motion of the individual points of the working bodies, it is developed the analytical model of the motion of the battery of the working bodies. On the basis of the provided analytical researches, they were determined geometrical parameters and developed experimental samples of the disk-knife working body. It was carried out a comparative test in the field of tools equipped with disk-knife working bodies and with standard spherical cut-off discs, which confirmed the effectiveness of the use of disk-knife working bodies. The use of disk-knife working bodies ensures: the burying of plant remains and fertilizers into the root-bearing soil layer, improving the quality of soil cultivation, preserving of its structure, reducing the traction resistance of the body.
