Compaction roller assembly and grader
First Claim
1. A compaction roller assembly, comprising:
- a lobed, non-circular impact roller operably mounted on a draw frame to produce a compacted, corrugated ground surface;
a grader operably mounted and cantilevered from a rearward end of the draw frame, for leveling the corrugated ground surface produced by the impact roller;
said grader operably mounted between an engaged position in engagement with the ground, and a storage position above the ground;
a parallelogram linkage pivotally interconnecting the grader with the draw frame; and
means connected between the draw frame and grader for selectively pivoting the grader on the linkage between the engaged and storage position;
said grader including a pair of elongated blades mounted on a pair of frame members, said frame members diverging rearwardly from a forward apex;
each blade being mounted on one frame member and extending the length thereof such that said blades diverge from on another as they extend rearwardly from the frame apex;
each blade having a lower edge depending below the frame member to which the blade is attached; and
said blade lower edges lying in a generally horizontal plane.

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.

11. A grader for leveling ground, comprising:
-
a pair of elongated blades mounted on a pair of frame members, said frame members diverging rearwardly from a forward apex; each blade being mounted on one frame member and extending the length thereof such that said blades diverge from one another as they extend rearwardly from the frame apex; each blade having a lower edge depending below the frame member to which the blade is attached; said blade lower edges lying in a generally horizontal plane; and a parallelogram linkage pivotally connecting said frame members with a tow vehicle, to maintain said blade lower edges in a generally horizontal plane during pivotal movement of the frame members. - View Dependent Claims (12, 13, 14, 15, 16, 17)
