The article is devoted to the improvement of the quality of tree-trunks delimbing by means of time-effective bringing the delimbing knife into an operating position before its contact with the branches. The set goal was achieved by bringing the delimbing knife into the operational mode, parallel to the direction of the tree-trunk feed motion, following the load shift of the pusher beyond the cutting edge. This type of load emerges when the branches press upon the pusher. After the stress is finished both mechanisms return to their original position. The described method and the construction of the mechanism provides placement of the delimbing knife in the operational position, thus enhancing the delimbing quality.
