ABSTRACT:

The hitch assembly includes a draw bar hitch pivotally mounted to the rear of the garden tractor, a tongue member mounted to and extending forward from the tiller, and a dual pivotal mounting universal joint releasably pivotally mounted to and between the draw bar and tongue. Removable pivot pins provide means for maintaining the universal joint in pivotally mounted relation between the tongue and draw bar.
