ABSTRACT:
An apparatus for the controlled lowering to the ground of a cut portion of a tree includes a rope and an anchor having an arrangement of guiding protuberances., each guiding protuberance including a bearing surface frictionally engaging and redirecting the rope without the rope fully encompassing any portion of the anchor including any of the guiding protuberances. Three guiding protuberances define a triangular arrangement. Of the three, a first guiding protuberance is disposed in proximity to an intermediate guiding protuberance defining a segment of a rope path therebetween, and a second guiding protuberance is disposed in proximity to the intermediate guiding protuberance defining another segment of the rope path therebetween without the segments crossing. A mounting member is attachable to the tree and a guiding member is pivotally connected to the mounting member along a pivot axis and includes an arrangement of guiding protuberances generally extending to each side thereof.
