Study of physical and mechanical properties and tillage modes of soil under modern technological principles

The availability of information about the physical and mechanical properties of the soil during the operation of tillage machines, including machines carrying out pre-sowing tillage, plays a key role in choosing the technological scheme and working bodies of the machine. The use of advanced tillage machines and technologies first of all requires studying the real situation of the corresponding physical and mechanical properties of the soil. From this point of view, the question raised has the same purpose. The studies were carried out on the territories of intensively agricultural regions and on samples taken from agricultural land. The results obtained during the experiment show that with an increase in the hardness of the soil from only 0.68 to 0.78 MPa, this cannot significantly affect the change in the resistivity of the working body. However, after this limit, an increase in the hardness of the soil significantly resists the working organ. In the course of the study, the physical and mechanical properties of the soil and the operating characteristics of the cutting body of the unit were also studied.
