SAW TYPE TREE FELLING HEAD AND METHOD OF FELLING TREES UTILIZING A FELLING HEAD

摘要

A method of felling trees and a felling head for doing the same. The method involves driving a horizontally sharpened blade on the felling head partially into a tree from one side and applying a selected force to the opposite side of the tree at a position above the cutting member, moving a driven saw on the felling head through the tree to cut the same and immediately the tree has been cut, shifting the same laterally onto a support plate. The apparatus includes a frame having a hydraulically operated sweep arm pivotally mounted on the frame for movement toward and away from an area in which the trees are collected and a plate on the frame for supporting the butt ends of the trees. The plate has a sharpened edge for penetrating a standing tree to be cut and an arm is mounted on the frame and movable toward and away from the cutting member so as to press the cutting member partially into the tree. A hydraulically driven chain saw is mounted on such arm and hydraulically operated for cutting through the tree as it is pressed against by the sweep arm.
