ABSTRACT:
A concrete finishing apparatus for smoothing and leveling partially set-up concrete at a support surface includes a frame portion, a first concrete working member and a second concrete working member disposed at the frame portion. The first concrete working member is rotatable about a first axis of rotation that is generally vertical when the first concrete working member is supported at a generally horizontal support surface. The second concrete working member is rotatable about a second axis of rotation that is generally vertical when the second concrete working member is supported at a generally horizontal support surface. The first and second concrete working members engage the partially set-up concrete surface at the support surface and rotate about the first and second axes of rotation to process the concrete surface.
