Abstract
A removable gooseneck for detachably connecting a tractor and trailer utilizes an elongate beam member attached to the hitch of the tractor and having an upstanding frame member depending from a rear end of the beam member. A foot is pivotally mounted at a lower end of the upstanding frame member for engagement with a front end portion of the trailer. A guide pin and link arrangement detachably connects the foot at a front end to the trailer and a locking pin and bushing arrangement detachably connects the rear end of the foot to the trailer at a location spaced from the guide pin and link arrangement. A power fluid ram extends between an upper portion of the upstanding frame member and the foot to selectively cause the foot member to swing upwardly and tilt the trailer downwardly for detachment of the gooseneck from the trailer and swing the foot downwardly to tilt the trailer upwardly for drafting.
