An analytical model for the evaluation of the efficiency of skidders by the transportation of saw logs in the forests considering definition of various influential parameter is presented. The calculations of the parameters were compared with the results of measurements in the real skidding conditions. The numerical results are showing, that it is uneconomic to skidd low charges, it is better to pull great loads, which are involving greate vertical forces in the zone of lover horizontal forces. To define the real efficiency the tractor axles dynamic loads have to be proved. Different efficiency parameters by skidding (rolling efficiency, wheel efficiency, tractive forces, dynamic loads of axles, tractive factor, rolling resistende of wood) are presented in the diagrams.
