A restraint apparatus limits pivotal movement of an attachment receiver which is pivotably coupled to movable first and second arms of a loader. The attachment receiver is configured to be coupled to a mounting frame of a work tool. The restraint apparatus includes an attachment member configured to be coupled to one of the first and second arms of the loader, a side plate coupled to the attachment member, and a blocking member coupled to the side plate. The blocking member is configured to engage the mounting frame of the work tool to block pivotal movement of the attachment receiver and the mounting frame relative to the first and second arms.

The invention claimed is: 1. A restraint apparatus for limiting pivotal movement of an attachment receiver which is pivotably coupled to movable first and second arms of a loader, the attachment receiver being configured to be coupled to a mounting frame of a work tool, the restraint apparatus comprising: an attachment member configured to be coupled to one of the first and second arms of the loader; a side plate coupled to the attachment member; and a blocking member coupled to the side plate, the blocking member being configured to engage the mounting frame of the work tool to block pivotal movement of the attachment receiver and the mounting frame relative to the first and second arms. 2. The restraint apparatus of claim 1, wherein the blocking member comprises an end plate coupled to the side plate spaced apart from the attachment member, the end plate having an inner surface located adjacent the mounting frame of the work tool. 3. The restraint apparatus of claim 2, wherein the blocking member further comprises a top plate coupled to the side plate above the end plate, the top plate extending over top portions of the attachment receiver and the mounting frame. 4. The restraint apparatus of claim 1, further comprising a fastener configured to couple the side plate of the restraint apparatus to the mounting frame of a work tool. 5. The restraint apparatus of claim 1, further comprising a fastener configured to couple the side plate of the restraint apparatus to the attachment receiver. 6. The restraint apparatus of claim 1, wherein the attachment member is coupled to one of the first and second arms of the loader by at least one fastener. 7. The restraint apparatus of claim 1, wherein the work tool is a backhoe attachment. 8. The restraint apparatus of claim 1, wherein the blocking member blocks pivotal movement of the attachment receiver while permitting the first and second arms of the loader to be moved up and down between an elevated position and a lowered position. 9. The restraint apparatus of claim 1, wherein the attachment member is an elongated bar configured to extend into a tube connecting the first and second arms of the loader. 10. The restraint apparatus of claim 9, wherein the elongated bar extends only partially across a width of the loader. 11. The restraint apparatus of claim 1, wherein the blocking member applies a force to the mounting frame and the attachment receiver in a direction generally perpendicular to a radius arm of the attachment receiver. 12. A restraint assembly for limiting pivotal movement of an attachment receiver which is pivotably coupled to first and second movable arms of a loader, the attachment receiver being configured to be coupled to a mounting frame of a work tool, the restraint assembly comprising: a first restraint apparatus coupled to the first arm of the loader; and a second restraint apparatus coupled to the second arm of the loader, the first and second restraint apparatuses each comprising an attachment member configured to be coupled to respective first and second arms of the loader and a blocking member, each blocking member being configured to block pivotal movement of the attachment receiver and the mounting frame relative to the first and second loader arms. 13. The restraint assembly of claim 12, wherein each blocking member comprises a side plate coupled to the attachment member, an end plate coupled to the side plate spaced apart from the attachment member and a top plate coupled to the side plate above the end plate, the end plate having an inner surface located adjacent the mounting frame of the work tool and the top plate extending over top portions of the attachment receiver and the mounting frame. 14. The restraint assembly of claim 12, further comprising first and second fasteners configured to couple the first and second restraint apparatuses, respectively, to one of the mounting frame of a work tool and the attachment receiver. 15. The restraint assembly of claim 12, wherein the attachment member is an elongated portion configured to extend into a tube connecting the arms of the loader. 16. The restraint assembly of claim 15, wherein the elongated portion extends only partially across a width of the loader. 17. A restraint assembly for limiting pivotal movement of an attachment receiver which is pivotably coupled to movable arms of a loader, the attachment receiver being configured to be coupled to a mounting frame of a work tool, the restraint assembly comprising: a restraint apparatus configured to engage a portion of the mounting frame of the work tool to block pivotal movement of the attachment receiver and the mounting frame relative to the loader arms; and means for coupling the restraint apparatus to the arms of the loader. 18. The restraint assembly of claim 17, wherein the coupling means secures the restraint apparatus to the arms of the loader without modifying the arms. 19. The restraint assembly of claim 17, wherein the blocking member blocks pivotal movement of the attachment receiver while permitting the arms of the loader to be moved up and down between an elevated position and a lowered position. 20. The restraint assembly of claim 17, wherein the restraint apparatus applies a retention force to the mounting frame and the attachment receiver in a direction generally perpendicular to a radius arm of the attachment receiver.
