Effectiveness of mechanized wood harvesting in a tree stand damaged by wind
Summary.

The paper contains an assessment of basic effectiveness indicators of wood processing and extraction in a 28-year-old pine stand, after a wide-area wind damage. The assessment was based on the effective work time. In the applied technological variant a harvester concentrated logging residues by putting them in stripes along the roundwood assortments. The research found similar relative values of work time spent on the roundwood production, as well as on concentrating the logging residues. The productivity of the harvester amounted to 8.85 m3/h when producing the roundwood assortments and 3.29 m3/h when forming logging residues stripes. The  extraction productivities for the roundwood assortments and the logging residues, over a distance of 150–200 m, were 18.75 m3/h and 6.86 m3/h, respectively.
