Abstract

A rim liner member attached to and covering the face of a gauge wheel rim adjacent a soil penetrating disk. The liner member has an exterior surface having a high lubricity which minimizes the build up of wet soil on the exterior surface. The entire liner member may be formed of low-friction polyethylene and it may be configured to conform to the face of the gauge wheel rims used by the manufacturers of planter, grain drills, and other soil working implements.

Claims

1. In a soil working implement including a frame, a soil opening disk attached to the frame, and a depth gauge wheel operably attached to the frame and disposed adjacent the disk to selectively control the depth the disk penetrates the soil, the gauge wheel including a wheel rim having opposed faces including a first face disposed adjacent the disk, the improvement comprising:

a liner member attached to and disposed to cover only the first face of the wheel rim, the liner member having an exterior surface closely conforming to said first face and formed of a material having high lubricity, whereby the buildup of soil on the exterior surface of the liner member adjacent the disk is minimized.

2. The improvement of claim 1 wherein the liner member is configured to be matingly received on and to conform to the first face of the wheel rim.

3. The improvement of claim 2 wherein the liner member includes openings disposed to register with openings in the wheel rim, and wherein the liner member is attached to the wheel rim by fasteners extending through the openings.

4. The improvement of claim 3 wherein the fasteners are threaded bolts and nuts.

5. The improvement of claim 1 wherein the exterior surface of the liner member is formed of polyethylene.

6. The improvement of claim 5 wherein the polyethylene is a linear low density polyethylene.

7. The improvement of claim 5 wherein the polyethylene is ultra high molecular weight polyethylene.

8. The improvement of claim 1 wherein the entire liner member is formed of polyethylene.

9. The improvement of claim 8 wherein the polyethylene is a linear low density polyethylene.

10. The improvement of claim 5 wherein the polyethylene is ultra high molecular weight polyethylene.

11. The improvement of claim 1 wherein the outer periphery of the liner member terminates adjacent the outer periphery of said first face of the rim.
