Abstract. The study is devoted to skidding wood under the canopy of a forest stand using small-sized skidding tools. An artificially created forest stand in flat relief conditions was chosen as the environment for studying the skidding system. The purpose of the study was to establish the influence of the characteristics of the forest stand on the parameters of the skidding system, which ensure its free movement between trees in the area, which will contribute to reducing the number of trees with mechanical damage due to their contact with the skidding system. The main parameters of the skidding system, which are taken as basic, are its overall dimensions, in particular the length, which can be changed by changing the length of the timber. The distances between trees in a row and the width of the forest stand, as well as the stand assessment data, were taken as fixed factors.
To achieve the research goal, a computer model was used that allows generating the skidding system operating environment, that is, a forest stand with an adopted tree placement scheme and a given deviation range from the scheme, as well as simulating and visualizing the skidding system movement in the generated forest stand, taking into account the skidding method and the angle of directional cutting of trees in the area. The basis was selected as piecemeal skidding of round timber using a "leash" mini skidder with appropriate equipment and the direction of tree cutting was taken into account, which will serve to select the initial position of the skidding system.
As a result of graphical and analytical processing of the research results, it was possible to obtain the main regression and dependence equations that establish the relationship between the characteristics of the forest stand and the parameters of the skidding system from the condition of its unhindered movement in the stand in terms of avoiding contact with growing trees in the area, which leads to their mechanical damage.
