Abstract

A tree-trimming apparatus mounted on a mobile support vehicle. The apparatus includes a telescoping boom pivotally mounted on a pedestal. The pedestal is pivotally mounted to a turntable which is rotatably mounted on the support vehicle. An operator's station is mounted on the pedestal to provide control of the apparatus. A large diameter circular saw is mounted at the end of the boom and is powered by a high speed hydraulic motor to provide high cutting efficiency. A fiberglass boom and electrically non-conductive hoses provide maximum safety for the operator.
