Abstract
A trailer hitch system for improving the speed and safety of attaching the trailer to a tow vehicle. The hitch may include a shank that may be attached to the trailer through a ball hitch. A receiver may be provided on the tow vehicle such that attachment of the trailer to the tow vehicle may be accomplished by introducing the shank into the receiver when the tow vehicle is backed to the trailer. A funnel shaped guide member may be provided to facilitate aligning the shank with the receiver. Also, friction reducing rollers may be used with the shank or the receiver. Moreover, a height adjustment and visual guidance system may be included to facilitate connecting the trailer to the tow vehicle. The shank includes a stop in a fixed position for limiting the depth the shank extends within the receiver.
