Abstract
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.
Claims5
A motor-powered concrete finisher, comprising a motor and a relatively rigid rotatable circular disc having an outwardly exposed flat disc-shaped surface and being rigidly and centrally mounted to a rigid hub, said rigid hub being rigidly mounted to the distal end of a shaft powered by the motor, the disc and hub being disposed at one end of a counter-balanced extension pole having an axis, the motor being at the other end of said extension pole, so that during use by an operator to finish curing concrete, said exposed flat disc-shaped surface of said disc will rotate directly against the surface of the concrete as it cures with its axis in a fixed relative position with respect to the axis of the extension pole.
