The aim of the study is to prevent the machine´s withdrawal from the technological trajec-tory in conditions of the slope agriculture. The object of study is the process of wheel tractor´s withdrawal of a given course in the mode of operation on sloping areas of the support surface. The results of theoretical studies of the power balance in the process of interaction between the tread elements with an inclined supporting surface are given. The functional relationship of pow-er given on the tractorexchange rate stability and configurational, geometric parameters of the tread´s working elements of the wheel mover.
