Abstract

An attachment for use with a skid steer loader having a single tine and a double tine connected at a center pin. The tines are configured to be powered open or closed about a vertical axis created by the center pin. The tines can be actuated by hydraulic cylinders. A scraper blade is included on the grabber attachment to allow the attachment to clear dead fall and brush. Side shields are included on the attachment to protect the tractor.

Claims

1. An attachment for use with a skid steer loader, the attachment comprising:

a back support plate;

a plurality of vertically arranged tines connected to the back support plate; and

means for opening and closing the plurality of tines.

2. The attachment of claim 1 wherein the plurality of tines comprises a single tine and a double tine.

3. The attachment of claim 1 and further comprising a blade located on the bottom of the support plate.

4. The attachment of claim 1 and further comprising means for attaching the attachment to the skid steer loader located on the back support plate.

5. The attachment of claim 1 and further comprising a center pin about which the tines pivot.

6. The attachment of claim 5 wherein each tine comprises a distal end and a tapered proximal end, wherein the distal end is connected to the center pin.

7. The attachment of claim 1 wherein the means for opening and closing the tines comprises a hydraulic cylinder operably coupled to the tines.

8. The attachment of claim 7 wherein the hydraulic cylinders are configured to power the tines inwardly to close the tines.

9. The attachment of claim 8 wherein the hydraulic cylinders are further configured to power the tines outwardly to open the tines.

10. A grabber attachment for use with a skid steer loader, the grabber attachment comprising:

a back plate;

a first tine mechanism and a second tine mechanism mating with the first tine mechanism, wherein the first and second tine mechanism are mounted vertically on the back plate;

a center pin at which the first and second tine mechanisms pivot; and

an actuator for opening and closing the first and second tine mechanisms.

11. The grabber attachment of claim 10 and further comprising a blade located on the bottom of the back plate.

12. The grabber attachment of claim 10 and further comprising brackets for attaching the grabber attachment to the skid steer loader.

13. The grabber attachment of claim 10 wherein the second tine mechanism comprises two tines.

14. The grabber attachment of claim 13 wherein the first tine mechanism comprises one tine.

15. The grabber attachment of claim 14 wherein the first and second tine mechanisms comprise a proximal end and a distal end.

16. The grabber attachment of claim 15 wherein the first and second tine mechanisms are tapered at the proximal end.

17. The grabber attachment of claim 16 wherein the first and second tine mechanisms are connected at their distal ends by the center pin.

18. The grabber attachment of claim 17 wherein the first and second tine mechanisms pivot about a vertical axis located at the center pin.

19. An attachment for use with a skid steer loader, the attachment comprising:

a back plate;

a single tine connected to the back plate at a distal end;

a double tine connected to the back plate at a distal end;

a vertically arranged center pin connecting the distal ends of the single and double tines so that the tines are configured to open and close by pivoting at the center pin.

20. The attachment of claim 19 wherein the tines are hydraulically actuated to open and close.

21. The attachment of claim 19 wherein the single and double tines comprise tapered proximal ends.

22. The attachment of claim 19 and further comprising a blade located on the bottom of the back plate.

23. The attachment of claim 19 and further comprising brackets for attaching the attachment to the skid steer loader.

24. The attachment of claim 19 and further comprising side shields on the back plate for protecting the skid steer loader.

25. The attachment of claim 19 and further comprising a brace attached to the back plate and configured to support the single and double tines below the center pin.
