To increase the versatility of a class 1.4 tractor in a small farm, a universal hydraulic mounted system has been proposed, which allows the tractor to be used without changeover, both for agricultural technological operations, and for loading and construction works. The article discusses the use of mathematical modeling in the MathLab, Simulink environment and the steep ascent method to identify the optimal values of the mass on the rear axle and the stiffness of the tractor tires when driving on a horizontal supporting surface. When studying the dependence of the change in the control coefficient from two factors of variation: the mass on the rear axle and the stiffness of the tractor tires, the response function was obtained. By the method of steep ascent, the optimal design parameters of a tractor with attachments were determined, which make it possible to ensure sufficient controllability when driving on country roads.
