Abstract
A concrete finishing machine includes a surfacing unit having two finishing cylinders and two augers mounted in line with the two cylinders, a pair of compacting rollers located on either side of the augers and suspended by a frame which is attached to the surfacing unit by a mounting assembly which allows adjustment in the vertical height of the compacting rollers relative to the surfacing unit for setting the compacting rollers relative to the surface being finished. The frame is adapted to be vibrated for vibrating the compacting rollers in use. The compacting rollers each have an outer peripheral planar surface extending about the periphery of the roller and a plurality of recessed planar surfaces spaced equally about the periphery of the roller.
