  • Patent number: 9944138
    Abstract: An automatically adjusting ball-mount hitch apparatus is disclosed having a hitch ball extending from a platform. A shaft extends from the platform and is slidably disposed within a sleeve. A hitch bar has a first generally horizontal arm adapted to be removably attached to a receiver hitch of a towing vehicle. A generally vertical arm of the hitch bar is attached to a coupling that is connected to or formed integrally with the sleeve. The shaft is capable of vertical movement within the sleeve in response to vertical forces applied to the platform, permitting the platform and the hitch ball to move vertically, independent of the hitch bar and the towing vehicle receiver, in an automatic fashion during use of the apparatus.
