The outcomes of assessing the possibility of reducing the technogenic impact on the soil during field operations in crop production are presented by increasing the stability of the transport movement and technological means in agricultural fields. An increase in the number of passes, a distortion of the tramline shape, an increase in slippage, wobbling and sliding of technical equipment on the field lead to a significant deterioration in the topography and structure of the soil layer, which causes soil destruction and a decrease in its productivity. Transport work performed on agricultural fields leads to a significant negative technogenic impact on the soil due to the numerous passes, large transported weight, and the application of trailers. The impact on the stability of the road trains movement is considered in the paper. Characteristics of damped oscillations are used to evaluate the efficiency of impacts on stability. The method of changing the inclination angle of the turntable kingpin of the road train trailer is chosen by the method of influencing the movement stability. It is established that changing the inclination angle of the turntable kingpin of the road train trailer allows reducing the average amplitude of oscillations of the trailer front side by 26.5-28%, increasing the period of oscillations by 33.3%, and also slightly changing the decrement of oscillations by 0.5-2.5%. Therefore, structural changes in the towing device of vehicles, by providing better directional stability, will reduce the technogenic load on the soil: decrease compaction and destruction of the soil layer.
