Abstract

A turf wheel having a wheel rim having an inner and outer surface, and an annular tread portion; a plurality of projections extending radially outward from the outer surface of the wheel rim, wherein each projection provides a stem, a ground contacting pad, and a ground engaging lug; and a hub. A wheel cleaning system having a frame provided by a wheeled apparatus; at least one turf wheel mounted to the frame; a turf wheel scraper assembly, the turf wheel scraper assembly providing a turf wheel scraper and an attachment mechanism, where the attachment mechanism is adapted to be mounted to the frame, and couples the turf wheel scraper to the frame.

Claims (31)

1. A wheel cleaning system, comprising a frame provided by a wheeled apparatus;

at least one turf wheel mounted to the frame;

a turf wheel scraper assembly, the turf wheel scraper assembly having a turf wheel scraper and an attachment mechanism,

wherein the attachment mechanism is adapted to be mounted to the frame, and couples the turf wheel scraper to the frame;

wherein the at least one turf wheel comprises a non-continuous tread having a plurality of projections and a plurality of tread voids; and

wherein each projection comprises a stem, a ground contacting pad, and a ground engaging lug.

2. The wheel cleaning system of claim 1 , wherein the turf wheel scraper assembly is configured to continuously remove debris from the turf wheel during rotation of the wheel.

3. The wheel cleaning system of claim 1 , wherein the turf wheel scraper is configured to contour the plurality of projections.

4. The wheel cleaning system of claim 1 , wherein the turf wheel scraper is configured to contour the ground contacting pad and the ground engaging lug.

5. The wheel cleaning system of claim 1 , wherein the turf wheel scraper is shaped such that it is able to pass over and around the ground engaging lug, and down an interior portion of the stem during rotation of the wheel.

6. A method of operating a wheel cleaning system comprising:

providing a wheel cleaning system having

a frame provided by a wheeled apparatus,

at least one turf wheel mounted to the frame,

a turf wheel scraper assembly, the turf wheel scraper assembly having a turf wheel scraper and an attachment mechanism,

wherein the attachment mechanism is adapted to be mounted to the frame, and couples the turf wheel scraper to the frame,

wherein the at least one turf wheel comprises a non-continuous tread having a plurality of projections and a plurality of tread voids, and

wherein each projection comprises a stem, a ground contacting pad, and a ground engaging lug;

mounting the attachment mechanism to the frame;

coupling the turf wheel scraper to the frame using the mounted attachment mechanism;

rotating the turf wheel with respect to the turf wheel scraper.

7. The method of operating a wheel cleaning system of claim 6 , further comprising using the turf wheel scraper to remove debris that may become lodged, form on, or adhere to the turf wheel.

8. The method of operating a wheel cleaning system of claim 6 , wherein the frame is provided by a non-rotating member of the wheeled apparatus.

9. The method of operating a wheel cleaning system of claim 6 , wherein the turf wheel provides a non-continuous tread having a plurality of projections and tread voids.

10. The method of operating a wheel cleaning system of claim 9 , wherein the turf wheel scraper passes over the plurality of projections.

11. The method of operating a wheel cleaning system of claim 9 , wherein the turf wheel scraper extends into and between the plurality of tread voids.

12. The method of operating a wheel cleaning system of claim 9 , further comprising passing the turf wheel scraper through the non-continuous tread.

13. The method of operating a wheel cleaning system of claim 7 , wherein the turf wheel provides a non-continuous tread having a plurality of projections and tread voids.

14. The method of operating a wheel cleaning system of claim 13 , wherein the turf wheel scraper passes over the plurality of projections.

15. The method of operating a wheel cleaning system of claim 13 , wherein the turf wheel scraper extends into and between the plurality of tread voids.

16. The method of operating a wheel cleaning system of claim 13 , further comprising passing the turf wheel scraper through the non-continuous tread.
