ABSTRACT:
A method of tree felling resulting in rearward displacement of the tree trunk, for a portion of its length from the tree stump so as to reduce stump to tree tip distance and lessen impact of the tree with the ground. An undercut area is formed by intersecting undercuts resulting in an inclined undercut surface deflecting the sawn tree butt in a direction rearward or opposite to that of the falling direction. On the backside of the tree, undercuts are made which intersect with one another to provide inclined surfaces retaining the fallen tree trunk on the stump. A modified method includes the steps of forming an initial backcut and a secondary backcut providing a ridge therebetween canted to the tree trunk so as to discharge the trunk to one side at the final stage of falling.
