ABSTRACT:
A mechanism for mounting an implement to a tractor is disclosed wherein the implement is provided with an articulated frame pivotally movable through a hydraulic cylinder to position a pair of mounting arms in alignment with attachment brackets affixed to the prime mover. Each mounting arm is provided with a threaded member threadably engaged with the end thereof and extending outwardly therefrom for insertion through an opening in the attachment brackets. A detachable collar is secured onto the threaded member by a removable fastener positioned on the opposing side of the attachment brackets from the mounting arm. A rotation of the threaded members into the mounting arms causes engagement of the detachable collar with the attachment bracket to draw the mounting arms into engagement with the attachment brackets. Wedge members are affixed to the mounting arms and the attachment brackets to cam the mounting arms to effect alignment between the threaded members and the corresponding openings. The implement is secured on the tractor by engagement of the mounting arms with the attachment brackets and support members spaced forwardly therefrom and retained in position by engagement of the collars with the attachment brackets.
