ABSTRACT:
An auxiliary implement mount which utilizes a triangular shape for attaching to a variety of shapes and sizes of tool bars of a first implement in a variety of positions.
A rod is pivotally attached by a pin through one of a series of holes arranged in a triangle configuration on a plate to the mount at one end thereof and to an auxiliary implement at the other end thereof. The rod is laterally stabilized by a bracket with a spring inside for exerting downward pressure and allowing vertical movement. The auxiliary implement is attached to the rod's other end by a wedge-shaped plate that utilizes a collar on the rod to tilt the implement at a desired angle to the ground.
