In this work, the determination of the connections between the characteristics of the cultivated soil and the frequency of the change in the cutting effort is carried out. In the case of destruction of agricultural soil (АS) with a displacement, the duration of the cycle of destruction is determined by the speed of the machine-tractor unit (MTA) and the deformation of the soil in the direction of cutting, sufficient for the displacement of the element along the surface of the slide. Due to high deformation rates, the ability of АS to resist deformations is estimated by the dynamic deformation coefficient. Creation of new energy-intensive, high-speed basic tractors and tractors causes increase of working speeds of aggregated with them cars. Taking into account that the MTA knife can, in most cases, be presented as a simple (double-sided) wedge, the effect of the speed on the АS digging resistance is found by a simple wedge.
