  • Publication number: 20060214391
    Abstract: The multi-task trailer hitch assembly of the present invention provides receiving tubes for the attachment of one or more trailer hitch-mounted receiver-type accessories while retaining a trailer hitch for pulling a trailer in the single hitch receiver provided on many trucks and ATVs. This permits the simultaneous use of multiple accessories while retaining the concurrent ability to tow. Multiple receiver tubes can be provided, both horizontal and vertical, and oriented not only toward the rear but also at right angles from the ball mount. This permits fastening one or more attachments from not only the rear but also from the top and inward from both sides toward the ball mount. Extra hitch ball mounts and other towing accessories may also be conveniently stored in the receiver tubes of the present invention while towing with a particular Class II or Class III hitch ball mount in the appropriate vehicle-mounted hitch receiver.
