ABSTRACT:
A universal auxiliary implement mount for agricultural implements utilizes spaced, parallel, triangular plate members for attachment and selective positioning on respective tool bars of different main implements. A draw tongue is pivotally attached to one pair of a pair of mounting apertures extending through central portions of the triangular plate members. A biasing rod has one end which is pivotally attached to the draw tongue and extends in an upward angle with the other end thereof received in an apex portion of the triangular plate members. The biasing rod has a spring therewith which selectively exerts downward pressure on the draw tongue while allowing vertical movement over rough ground surfaces. The triangular plate members are selectively positionable longitudinally and rotatably on the tool bar whereby, in one mount position, the draw tongue is pivotally affixed to the mount by one pair of mounting apertures and in another mount position, the draw tongue is pivotally affixed to the mount by a second pair of mounting apertures. The spaced draw tongue mounting apertures permit the mount to be variously positioned on a tool bar while maintaining equal geometric relationships between the triangular plate members, the draw tongue and the biasing rod.
