Abstract
A concrete finishing machine includes a surfacing unit having two finishing cylinders with two augers mounted in line with the two cylinders, and a pair of compacting rollers located on either side of the augers, 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 compactor rollers in use. In one embodiment, the compacting rollers each have rectangular fins projecting radially outward from the roller and extending the length thereof. In another embodiment, the compacting rollers each have a serrated outer surface.
