Abstract

A low impact turf wheel having a wheel rim including an inner and outer surface, a plurality of pegs extending radially outward from the outer surface of the wheel rim, wherein the plurality of pegs maintain the wheel rim above an area of turf, and a hub. A turf wheel having a wheel rim having an inner and outer surface, a plurality of pegs extending radially outward from the outer surface of the wheel rim, wherein the peg comprises a stem, a collar and a lug, and wherein the lug includes a limited surface area to provide a ground contacting tread, and a hub.

Claims (21)

1. A turf wheel, comprising:

a wheel rim having an inner and outer surface;

a plurality of pegs extending radially outward from the outer surface of the wheel rim, wherein the plurality of pegs each comprise a stem and a lug, wherein the plurality of pegs maintain the wheel rim above an area of turf and provide a ground contacting tread;

a non-continuous tread comprising the ground contacting tread and tread voids; and

a hub;

wherein the lug further comprises a lug face, and wherein the lug face is T-shaped.

2. The turf wheel as recited in claim 1 ,

wherein the ground contacting tread comprises 30% and the tread voids comprise 70% of the total surface area of the outer surface of the wheel rim.

3. The turf wheel as recited in claim 1 , wherein each peg further comprises a collar extending perpendicularly outward from the stem.

4. The turf wheel as recited in claim 1 , further comprising a contact surface ratio of 1:3, wherein the contact surface ratio is the ratio of the ground contacting tread to the total surface area of the outer surface of the wheel rim.

5. The turf wheel as recited in claim 1 , wherein the hub comprises a central portion and a branched network.

6. The turf wheel as recited in claim 5 , wherein the branched network extends radially outward from the central hub and is affixed to the wheel rim.

7. The turf wheel as recited in claim 6 , wherein the branched network includes a web structure separated by a plurality of apertures.

8. The turf wheel as recited in claim 7 , wherein the web structure prevents a build-up of turf material in or around the central hub.

9. The turf wheel as recited in claim 1 , wherein said stem is substantially rectangular in shape.

10. The turf wheel as recited in claim 1 , wherein the stem further comprises a stem surface.

11. The turf wheel as recited in claim 1 , wherein the plurality of pegs are offset from one another yet evenly distributed about the outer surface of the wheel rim.

12. The turf wheel as recited in claim 1 , wherein the plurality of pegs comprises a first peg series and a second peg series.

13. The turf wheel as recited in claim 12 , wherein said first peg series and second peg series are offset from one another.

14. The turf wheel as recited in claim 3 , wherein the lug abuttingly engages with the collar.

15. The turf wheel as recited in claim 1 , wherein the ground contacting tread includes between 10% to 50% of the total surface area of the outer surface of the wheel rim.
