Carrying out agrotechnical operations at various agrofons and transporting agricultural goods across fields and field roads is accompanied by the impact on the soil cover of wheeled and tracked tractors, combines, trailers and other technical means involved in the technological process of cultivation and harvesting of crops. The interaction of the movers with the soil is accompanied by its deformation by the contacting working elements of the movers, which significantly affects the resistance to movement of the agricultural unit. To assess the ability of the soil to resist deformation, a number of dependencies are proposed, based on a pattern that estimates the amount of soil deformation from the applied load when a stamp of various sizes is pressed into it. A number of factors influence the deformation of the soil when exposed to a mover: the type of soil, the thickness of the fertile layer, the presence or absence of a turf layer intertwined with the root system of plants, the presence or absence of a dense clay sub-arable base, soil moisture, its structure, other factors. When assessing the ability of the soil to deform under the load caused by the immersion of agricultural machinery movers into it, it is difficult to take into account the influence of all factors involved in this process. However, it seems possible to assess the stress state of the soil during the introduction of deformers into it by analyzing some indicators that change as the depth of the introduction of the deformer increases, as well as analyzing the intensity of changes in these indicators. This article attempts to obtain a dependence that comprehensively reflects the influence of soil conditions on the resistance to indentation of the movers and also provides some results of research aimed at developing such a dependence.
