Abstract
Abstract A combination push and tow bar/hitch assembly including a pair of spaced apart parallel outwardly extending mounting bars pivotally attached at their lower ends to the front frame of a motor vehicle. A first transverse brace member is positioned between the mounting bars near the center point and a second transverse brace member is positioned between the outer ends of the mounting bars. A U-shaped frame with a coupler at its apex is pivotably attached to the second transverse brace for use when the bar/hitch is in the horizontal towing position. A ball mounted at the midpoint of the first transverse brace is engaged by the coupler on the U-shaped frame to lock down the frame when the bar/hitch is upward in the push position.
