ABSTRACT:
A weight distributing hitch for towing a trailer behind a vehicle includes a hitch bar for mounting to the vehicle and a ball mount head for mounting on the hitch bar at a selected tilt angle. A pair of spring bars are mounted to the ball mount head. These spring bars distribute the weight of the trailer relative to the vehicle. Each spring bar is substantially L-shaped and includes a turned groove at a proximal end received in a cooperating aperture in the ball mount head. A retainer of spring steel engages in the grooves to hold the spring bars in position. The relative tilt angle of the ball mount head is adjusted by means of an eccentric angle adjusting element in the form of a washer. This washer is fixed to one of the ball mount head or hitch bar and includes a cam surface for engaging the other of the two elements.
