The results of the study of the possibility to improve the process of mechanized hitching of machines and tools into the center zone of self-propelled chassis, using a folding frame and a front balancing swivel axle, are presented. Research and studies that had been carried out earlier in Ukraine and other countries did not allow to solve this problem by the simpler methods. The use of a front swivel axle makes it possible to solve the problem of an automated hitching of implements and tools in the center zone, improve maneuverability and simplify the steering drive of a self-propelled chassis. The scientific novelty of this research is a dynamic model of the vehicle turning in place around one of the rear wheels, when the front axle is turned at an angle close to 90 degrees. The use of a balanced front axle can significantly reduce the moment of resistance to turning. The latter phenomenon has not been studied in the known publications. The aim of the study is to increase the maneuverability of a universal-row-crop tractor self-propelled chassis, including the process of mechanized hitching of implements and tools in the center zone when using a folding technological frame. The use of a swivel front axle allows us to get an ideal turn with any changeable front wheel track that might be changed during the operation of the vehicle. The conditions that make it possible to turn the machine around one of the rear wheels are determined.
