Abstract

Changes in the performance of harvesters of different power classes depending on the size of felled trees in thinned stands were assessed using a time study method. Results were compared to values from the catalogue for chainsaw performance. Comparison of the productivity of these two ways of harvest indicated that, depending on the volume of the felled tree, it was 6−8.2 times higher for harvesters. However, significant differences in productivity between harvester classes were also found. For felling trees with sizes up to 0.07 m 3 , the productivity of a small−power harvester is about 30% higher than that of a medium and high−power ones.
