Abstract

A work vehicle includes a frame, a cab structure pivotably connected to the frame and an implement connected to the frame. A body is disposed between the cab structure and the implement to sufficiently limit pivotal movement of the cab structure with respect to the implement to prevent damage to the cab structure by the implement.

Claims (28)

1. A work vehicle comprising:

a frame;

a cab structure has a pivotal connection with the frame, the cab structure having at least front and rear walls to surround and protect the operator;

an implement connected to the frame, wherein the cab structure is forwardly pivotable, with respect to the frame, towards the implement; and

a protective device disposed between the cab structure and the implement to substantially limit pivotal movement of the cab structure with respect to the implement to prevent contact between the cab structure and the implement, wherein the protection device has side walls with front and rear surfaces extending therebetween, the rear surface of the protection device coupled to a lower portion of the front wall of the cab structure adjacent to a the pivotal connection between the cab structure and the frame, further wherein the front surface of the protection device contacts the implement when the cab structure is pivotally rotated about the frame.

2. The work vehicle of claim 1 , wherein the body is removably connected to the cab structure.

3. The work vehicle of claim 1 , wherein the body is removably connected to the implement.

4. The work vehicle of claim 1 , wherein the body is manually removable from the implement.

5. The work vehicle of claim 1 , wherein the body is composed of a substantially rigid material.

6. The work vehicle of claim 1 , wherein the body is composed of a substantially non-marring material.

7. The work vehicle of claim 1 , wherein the cab structure includes a door.

8. The work vehicle of claim 7 , wherein the door is pivotably connected to the cab structure.

9. The work vehicle of claim 7 , wherein the body is connected to the door.

10. The work vehicle of claim 9 , wherein the connection between the body and the door is a tethered connection.

11. The work vehicle of claim 10 , wherein the body is connected to the cab structure.

12. The work vehicle of claim 11 , wherein the body is manually removable from the cab structure.

13. A method for limiting rotational movement comprising:

disposing a protection device between a cab structure and an implement of a work vehicle, the cab structure having at least front and rear walls to surround and protect the operator, the cab structure having a pivotal connection with a frame of the work vehicle, and the implement pivotably connected to the frame, wherein the cab structure is forwardly pivotably, with respect to the frame, towards the implement; wherein the protection device substantially limits pivotal movement of the cab structure with respect to the implement to prevent contact between the cab structure and the implement, wherein the protection device has side walls with front and rear surfaces extending therebetween, the rear surface of the protection device coupled to a lower portion of the front wall of the cab structure adjacent to the pivotal connection between the cab structure and the frame, further wherein the front surface of the protection device contacts the implement when the cab structure is pivotally rotated about the frame.

14. The device of claim 13 , wherein the step of disposing the body includes removably connecting the body to the cab structure.

15. A work vehicle comprising:

a frame;

a cab structure having at least front and rear walls to surround and protect the operator, the cab structure has a pivotal connection with the frame;

an implement connected to the frame, wherein the cab structure is forwardly pivotable with respect to the frame, towards the implement; and

a protection device disposed between the cab structure and the implement to substantially limit pivotal movement of the cab structure with respect to the implement to prevent contact between the cab structure and the implement, wherein the protection device has side walls with front and rear surfaces extending therebetween, the rear surface of the protection device coupled to a lower portion of the front wall of the cab structure adjacent to the pivotal connection between the cab structure and the frame, further wherein the front surface of the protection device contacts the implement when the cab structure is pivotally rotated about the frame.

16. The work vehicle of claim 15 , wherein the body is removably connected to the cab structure.

17. The work vehicle of claim 15 , wherein the body is removably connected to the implement.

18. The work vehicle of claim 15 , wherein the body is manually removable from the cab structure.

19. The work vehicle of claim 15 , wherein the body is removably connected to the door.
