The communication establishment between indices of operational efficiency and passability of the wheel tractor with the hydromechanical transmission, giving the opportunity to carry out the specified operational property assessment at modern level, is revealed in the article. The research results on the influence of the trip load on the operational efficiency and passability indices of the wheel skidding tractor are given.
the wheel skidding tractor, hydromechanical transmission, skidding portage, passability assessment
