Fuel and lubricant consumption in the thinning of young oak-hornbeam stands was studied. The study results are a significant base for the calculation of thinning costs, as well as for the planning of these operations. Based on the elements of statistical analysis on the dependence of fuel and lubricant consumption on tree diameter, it was assessed that with the increase of tree diameter, the fuel and lubricant consumption per unit of product decreases. The dependence of fuel and lubricant consumption on diameter size was evaluated separately for felling on tractor skid roads (clear felling), and on the plots-areas between tractor skid roads (selective thinning). In both cases, it is represented by the fuction. Taking into account the results of the analysis of variance, for practical purposes, the unique norms of fuel and lubricant consumption for both skid roads and plots were adopted.
