ABSTRACT:
A remotely-operated chain saw apparatus useful for cutting overhead branches from ground level. A telescopic tube-shaft means extends between an engine at ground level and a gear box attached to a chain saw guide bar. A person standing on the ground can use the apparatus to cut off overhead branches without leaving the ground. The chain saw is adjustable so that the cutter chain can cut into the upper surface of a tree branch or into a side surface of the branch.
