Wood extraction by cable yarders represents transport with the load partially or completely lifted from the soil, where the interaction soil-machine is minimal or completely eliminated. The productivity and cost of wood extraction by cable yarder “Mounty 4000” depending on the most important influential factors were analyzed in this research. The productivity was determined by work and time study. The share of productive work time was 79.7%, and allowance time 20.3%. Work productivity decreased by yarding distance increasing, from 82.05 to 31.39 m3/WD. Direct unit costs increased with yarding distance increasing, from 24.49 to 64.03 BAM/m3. Time study analysis and time of cable yarder set up and dismantle pointed to the excellent training of the workers and the very good work organization. The results of performed work and time study are similar to the results of other researches for comparable work conditions.
