A compaction roller assembly (10) includes a lobed non-circular impact roller (12) operably mounted on a draw frame (14) and a grader (16) operably mounted behind the impact roller (12) to level the corrugated ground surface produced by the impact roller. The grader (16) includes a pair of diverging frame members (22) with a pair of blades (54) mounted thereon and depending therefrom with the lower edges of the blades lying within a generally horizontal plane. A plurality of teeth (60) may be mounted to the frame members (22) to scarify the soil, each tooth (60) being removably connected to the frame members to permit ease of conversion between a grader blade and a scarifier. Each tooth (60) is a generally flat plate, the plates oriented parallel to one another and parallel to the line of travel of the grader (16). Each tooth plate forward edge (68) 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 (86) are provided to the frame member for supporting the grader in fine particulate soil.
