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.

Tree-trimming apparatus

A hydraulic actuator, readily assemble and disassemble, which can be used for effecting actuation of food processing machinery or bulk bait or other commodity dispensers. Since it is necessary that such devices be safe and non-polluting, components which come in contact with the hydraulic fluid can be made of plastic so that tap water can be utilized as the hydraulic fluid. The actuator is made readily assemble and disassemble by including devices for quick and easy sealing and locking of the component parts. These devices have only a minimal number of subcomponents.
