AbstractIn recent decades, in our country insufficient attention has been paid to the study of soil mechanics. Currently, there is a need to study the mechanical processes in the soil when it interacts with the working bodies of tillage machines and operating systems of mobile agricultural equipment. With existing technologies for cultivating crops, various machines pass through the field from 10 to 15 times. The tools used have a centuries-old history of development and improvement, both of individual types of working parts, and of technological tillage complexes as a whole. At the same time, the scientific basis for tillage has not yet been fully developed. The article explores soil mechanics and intensification of agriculture; saturating it with heavy machines, and increasing the energy saturation of tractors put forward new tasks that cannot be solved without the development of theoretical and applied research in the field of soil mechanics. Depending on the formulation of the tasks of the interaction of tillage organs and movers with soil, degenerate models can be used that contain only those rheological properties of the soil that define the main goal of the technological problem.
