Soil structure is the most important indicator that largely determines soil fertility, as well as moisture, mechanical and technical properties. The process of developing a cultivator consists of several successive stages: setting a task and writing a technical task; formulation of technical solutions; design and manufacture of prototypes and their testing; development of design documentation for manufacturers; machine production. Equipment should only be replaced when an economically viable new technology solution becomes available. The intensification of agricultural production is directly related to the increase in the number and weight of machines and the number of them moving across the field.

With the mechanization of agricultural production activities, the goals of scientific and technical actions should be to increase labor productivity, reduce specific energy costs, improve the quality of work, improve working conditions, automate operations, and reduce technogenic environmental loads from the development of new technology. It has been established that with the existing processing technology, different machines pass through the field up to 10 ... 15 times, and mice compact more than 80% of the surface. Intensive farming with repeated use of single-tool tools and machines leads to a decrease in the natural fertility of the soil, which leads to serious changes in its agrophysical properties and disrupts the course of biological processes.

The article developed a mathematical model of the operation of a mounted combined tillage unit, which makes it possible to determine the speed of its movement during pre-sowing tillage. It is presented in the form of regression equations that allow you to set the optimal parameters and operating mode of the combined tillage unit, and the analytical dependence of the roller diameter on the size of the clods is also established.
