METHOD OF TREE FELLING Abstract A method for felling large trees including the con- ventional steps of cutting an undercut and backcut so as to leave a quantity of intact holding wood intermediate the inner extremes of the undercut and the backcut. Kerfs are cut inwardly into the tree from the undercut to remove a quantity of holding wood thereby causing calculated weak- ening the wood to assure a relatively clean line of sever- ance between the stump and the log butt. Side cuts may also be made into the holding wood to diminish the chances of extracting a root, with attendant risks of injury as well as for aiming of the tree.
