发明名称 Motor powered, pole-mounted concrete finisher
摘要 A motor-powered concrete finisher, having a motor and a rotatable circular disc powered by the motor are attached at the end of a counter-balanced extension pole. A handle may be provided at or near the balance point of the extension pole. The motor may be disposed on the rear end of the extension pole, to assist in counterbalancing the weight of the circular disc, hub, front end of the extension pole and other weight on the front end of the extension pole. An angled gear drive on the front end of the extension pole, driven by a shaft extending through the extension pole, has an attachment hub at its end for attachment of the circular disc. The motor may be an internal combustion engine. The concrete finisher may be a weed trimmer having the weed trimmer attachment replaced by a rotatable circular disc.
