摘要：The article considers the justification of the parameters of wheeled tractors and arable aggregates taking into account zonal conditions. The system of forming a promising size range of wheeled tractors and agricultural units for separate enterprises, agricultural zones and the whole country was based on scientifical principles of operational technologies of mechanized work that establish the basic levels and tasks of adapting energy resources to natural-production conditions. In developing models and an algorithm for optimizing operational parameters, the most objective indicators were applied, including the optimal net productivity of the arable aggregate for different classes of rut length and the tractor's density. We established the optimal and maximum permissible in operation () values of the density of wheeled tractors for the set of production conditions, regardless by rut length according to the results of modeling and field tests. The rational mass and energy parameters of the tractors for each rut length class were justified, included in the size range of the proposed two-parameter classification system and the corresponding values for the width of the arable unit.
