ABSTRACT:
A compaction roller assembly includes a lobed non-circular impact roller operably mounted on a draw frame and a grader operably mounted behind the impact roller to level the corrugated ground surface produced by the impact roller. The grader includes a pair of diverging frame members with a pair of blades mounted thereon and depending therefrom with the lower edges of the blades lying within a generally horizontal plane. A plurality of teeth may be mounted to the frame members to scarify the soil, each tooth being removably connected to the frame members to permit ease of conversion between a grader blade and a scarifier. Each tooth is a generally flat plate, the plates oriented parallel to one another and parallel the line of travel of the grader. Each tooth plate forward edge includes a concave arc-shaped lower portion extending from the lower end of the tooth to a point proximal the lower edge of the blade. Removable support skids are provided to the frame member for supporting the grader in fine particulate soil.
