The modern level of mechanization of agricultural enterprises with large land areas in their turnover is characterized by the presence of a significant number of wheeled energy-saturated semi-frame tractors of 5–8 traction class. The use of tractors of this class on small-contour fields of the central and northern agricultural zones of the Amur region, characterized by the significant presence of slope fields with a slope angle of more than 5 degrees, does not correspond to the parameters of efficiency and safety. It should also be noted that small peasant farms also play a significant role in the production of agricultural crops in the Amur region, while the volume of products produced by them is up to 28 % of the total gross crop production in the region. At the same time, it is noted that most of the small-scale fields of the region belong to and are cultivated by the farms. The need for their processing is reflected in the formation of machine and tractor parks of this category of farms. What determines the use of tractors of class 1.4–2 for agricultural work, while their technological characteristics require improvement through the introduction and application of new technical solutions. The article deals with the issues of forming the performance of a promising wheeled machine-tractor unit equipped with a loading-stabilizing device, the novelty of which, the inventive level and industrial applicability are confirmed by a patent of the Russian Federation for the result of intellectual activity. An original mathematical apparatus is proposed that contributes to the calculation of the efficiency of the machine-tractor unit. It is established that the installation of the device of the proposed design in the running system of the unit is able to increase the working speed both during field work and during movement along transport routes, reduce slipping, increase the utilization factor of shift time.
