Roller plow assembly for concrete screeding machine

摘要

A screeding machine for screeding an uncured concrete surface includes a wheeled unit having a plurality of wheels for moving the wheeled unit over a support surface. A screed head assembly includes a grade setting device and a vibrating member and is movable over the concrete area via the wheeled unit. The screeding machine includes a roller that is rotatably mounted at the screed head assembly and rotatably driven about its longitudinal axis. The roller is rotatably driven by a rotatable drive motor that is operable independently of the vibrating member or grade setting device. The grade setting device or roller plow assembly may be provided as an aftermarket kit for attachment at a screed head assembly of a screeding machine.
