Abstract
The present research study demonstrates the procedure of formation of mathematical models of efficiency of a driving system set and traction in tractors. The efficiency models are presented in the form of a second and third-degree polynomial. The procedure is illustrated by concrete examples of efficiency models of a driving motor, pump, hydro-motor and traction in a tractor. Coefficients in regression polynomials are determined by applying the least square method. It is on the basis of the models obtained that the efficiency is graphically represented in the form of relief topographic characteristics.
