Abstract
A rotating tube concrete finisher is controlled and driven by an end handle assembly including an internal combustion engine. An outrigger wheel unit is coupled to the end handle assembly to form a stable end support for the end handle assembly and to support the weight of the end handle assembly including the engine. A pair of end handle assemblies can be coupled to opposing ends of a cylindrical finishing roller and may be selectively operated to drive the finishing roller in either a first or a second direction of rotation. A winch system facilitates uphill and downhill translation of the concrete finisher on a sloping concrete surface and enables the system to be operated by one man without undue effort.
