Abstract
The paper deals with establishing the relationship between the traction factor and different parameters, such as the coefficient of rolling resistance, slip, some kinds of skidder efficiency, as well as other characteristics, and their change in correlation the tractive force and power. The analysis was made skidding different forms of wood: whole trees, tree length, long logs, logs and assortments. The traction factor is an exploitation parameter, the so-called net traction factor. It shows which part of the adhesive loading of a tractor can be used as draught. The general advice may be to perform skidding with minimum resistance but with maximum traction factor value.
