Investigating the influence of logging technology based on the LOKOMO MAKERI 34 T harvester and the LKT 81 special forest wheel tractor as to damage caused to trees and soil and making a comparison with classical technologies used in tending operations in conditions of this country, it has been established that damage to trees in spruce stands (22.5 per cent) shifted to roots (14.4 per cent) and butts (3.9 per cent). Damage to soil was limited to turning up the upper humus layer which occurred mainly while revolving the machine by more than 45 degrees and did not exceed a depth of 50 mm. There was a difference also in the direction of felling and the storage of felled trees in the optimum angle (up to 45 degrees) to the skidding line (88 per cent for the harvester and 56 per cent in classical technology).
