Abstract

A method of logging a tree includes the steps of cutting the tree part way through the trunk near the bottom with two cuts lying in generally the same plane to leave a connecting portion (holding wood) between the resulting two generally parallel cut edges, and driving support wedges or the like into both said cuts to stabilize the tree trunk. A
helicopter above the tree is connected to a point near the top of the trunk. The helicopter is moved away from the tree, thereby breaking the connecting portion (holding wood) and allowing the upper portion of the tree to be carried away by the helicopter. The method utilizes a grapple connected to the helicopter by two cables, one connected to the helicopter below the pilot's seating position and another bellow the center of gravity.
