Abstract
Abstract A convertible hitch for towing a trailer or the like includes a gooseneck arm for use as a hitch of that type. The gooseneck arm is braced by an A-frame tongue, and the hitch is converted to the bumper type by detaching the forward end of the tongue from the gooseneck arm, swinging the same down and attaching it to the rear of the towing vehicle in the usual manner. The gooseneck arm in turn is foldable back upon itself against the forward end of the trailer. All the foregoing is accomplished simply by the removal or insertion of several pins so that the hitch can be readily converted from one form to the other.
