Evaluation of small-sized skidders performance

Abstract

The aim of the work is to further develop theoretical description of interaction between small-sized forestry vehicles and soils, to study productivity and indicators of interaction of wheeled and tracked vehicles with weaker forest soils. According to the calculation results it was established that the LMT-3 wheeled skidder when working on weakly-bearing soils is able to provide productivity when skidding trunks within 43 m3 per shift, with the trunks to be skidded for the tops. Productivity of small-sized tracked vehicle LMT-6 is slightly lower and makes up to 39 m3 per shift when trunks are skidded for the tops. For both tractor models, the productivity of skidding is reduced by approximately 5 m3 per shift when the trunks are to be skidded for the bottoms.
