AbstractPaper presents the results of research on the productivity and economic effectiveness of timber harvesting in stands managed under complex cutting systems. Use of the operating time of a work−shift, including wood processing, loads preparation for skidding and changes at work sites, was low and amounted to 0.62. The main categories of the operating time were delimbing (45%) and travelling (31%). The unit costs of work of a harvester in the analysed stands were higher amounting to 69 PLN/m3 for eight−hour shifts and 110 working days a year, and 40 PLN/m3 for sixteen−hour shifts compared to the work of the saw operator (32 PLN/m3 for the eight−hour shift).
