The article deals with the calculation the most important indicators to determine the effi-cincy of skidders for certain soil conditions, i.e. – resistance to a skidder wheel interaction; - net thrust of the mover with soil; - drawbar pull coefficient. Calculations are based on WES-models, widely spread among foreign researchers.
