The paper proposes a technique for determination of the optimal operating weight of the farm tractors in a calculation-involving way. It is illustrated by calculating the weight of the most widely spread tractor in Bulgaria of class 14 kN with wheeled formula 4K2. The calculations account for the limiting conditions in the admissible slipping and the admissible average specific pressure of the motive unit on the soil for agricultural reasons, for the type load-carrying capacity, for the minimum normal reactions on the front axle, for the maximum allowable value of the traction factor, etc. In the optimization of the weight is utilized the program Solver, included in the electronic table Excel. Different options of the service conditions are considered and recommendations are given on the selection of the optimal operating weight of the tractors subject to the relative share of the kinds of works, which they carry out within their annual occupation.
