Abstract
The adjustable trailer hitch assembly of the present invention is designed for attachment to the head of most commercially available trailers. The adjustable trailer hitch assembly includes a first weldment member pivotally attachable to a head of a trailer, and a second weldment member operably connected to the first weldment member for lateral movement between extended and locked positions. Collapsible extension arms operably connect the first and second weldment members providing movement between the extended and locked positions. The collapsible extension arms are positionable between a first collapsed position with the first and second weldment members adjacent one another defining the locked position, and a second extended position with the first and second weldment members separated from one another defining the extended position. A vehicle connection element is operably connected to the second member, with the vehicle connection element moveable along a vertical length of the second member for connection to a tow vehicle.
