Based on theoretical studies, the article substantiates an efficiency increase in the of car operation by improving stability in slope farming conditions. Violation of transverse stability depends on the driving conditions, the redistribution of loads on the axis of the vehicle skid. To ensure the reliability and controllability of vehicles on hillside surfaces when transporting multiton agricultural goods, it is necessary to take into account the change in operational and technical parameters due to the position displacement of the vehicle mass center. In this regard, in order to assess the performance of the car, a theoretical assessment of the use of the special device "Frame load regulator" – a redistributing device designed to increase the longitudinal and transverse stability of the car, was made. It has been found that when the frame load regulator is turned on, the center of mass of the car shifts and, as a result, the restoring moment increases due to an increase in the arm of the normal component of gravity. Thus, the effect of the frame load regulator on the vehicle structure is characterized by an increase in the vehicle stability stabilization coefficient. The analysis of theoretical studies showed that the vehicle efficiency increase when performing transport work in slope farming conditions is ensured by the use of the proposed frame load regulator, which allows increasing transverse stability, maneuverability and speed of the vehicle by redistributing the grip weight in the design of the power vehicle.
