Sažetak
By increasing the diversity of conditions influencing the forest operation we are often faced with the dilemma of combining Motor manual and Cut to length technologies. The results of time study and productivity of cutting and skidding operation in mixed stands with a substantial proportion of deciduous trees are presented. Older pole stand was divided into four homogeneous strata in which forest operation was executed by applying two different technologies (motor manual and cut to length), each on two research areas. The objective of this study was to identify the influential factors which could be used as guidelines in the decision support system evaluating the suitability of both technologies. The results show that the mechanized cutting productivity is statistically significantly different for different tree morphological characteristics. In order to set up general guidelines it was established that the productivity in stands with single-trunked, short crown and thin branches processed with Cut-to-length technology is 25% higher than in the comparable stands consisting of multi-trunked trees, deep crowns with thick branches in terms of diameter at breast height structure.
