The effects of work on felling and cross-cutting of forest assortment were studied in artificially established black locust stands in Srem. Felling and cross-cutting of forest assortments was performed in two stands, with the application of the assortment method. The measurements were performed in compartment 11-1 and in compartment 40 c. Organisation work form was 1MR. Felling conditions differed regarding: plantation age, felling time and underwood density. Based on the analysis, it was concluded that there were no statistically significant differences between cross-cutting times of unit products in these stands. Cross-cutting time of unit products was calculated based on the mathematical model of simple regression analysis, obtained for pooled data for both stand situations. The grouping was based on the results of the analysis of variance. Fuel and lubricant consumption was also analysed in addition to the analyses of unit product cross-cutting time. The fuel and lubricant consumption was calculated based on the mathematical model of multiple regression analysis, in which the variables were the diameter and volume percentage of technical roundwood. Work norms, as well as the fuel and lubricant consumption standards were used in the calculation of unit costs of felling and cross-cutting in these working conditions.
