ABSTRACT:
The present invention relates to a relatively lightweight, portable, hand controlled finishing machine for finishing cement like surfaces. The cement finishing machine comprises an elongated shaft that makes up the main frame thereof, and a rotary wheel rotatively mounted to said elongated shaft and driven by an electric motor also mounted to said elongated shaft. Finishing elements such as rocks, brushes, or even trowels are detachably secured to an outer exposed radial face of said rotary wheel. In operation, the cement finishing machine is supported adjacent a wall or surface to be finished and during the course of operation, an operator is able to manipulate and control the main frame such that the finishing elements engage and act upon the surface being worked.
