The purpose of the research was to analyse the labour consumption and output of several technological processes of fuel wood chip harvesting. Potential woody biomass that can be used for energy purposes can be found in the wood that is harvested in the course of improvement cuttings and final fellings. Therefore the processes studied were those of wood harvesting in late cleanings, early and late thinnings and final fellings. In principle, the potential of fuel wood should be sought in pine tree stands, as this species prevails in our forests. Among the technological processes analysed, the LC-PI-WS process was the most labour consuming one, with labour consumption reaching 4.76 h/m³. The most labour consuming technological operation in this process was delimbing with an axe (2.44 h/m³) and horse skidding on a strip road (1 h/m³). The least labour consuming operation was chipping with a DVWB 112 disc chipper mounted on a Ursus 1204 tractor (labour consumption 0.13 h/m³). The process of machine wood harvesting in final felling (FF-PI-CW-M) was the least labour consuming one.
