A tow bar for connecting a motorized utility cart to a shopping cart includes a second tow bar segment pivotally attached to the first tow bar segment at a first hinge that defines a first axis; a third segment pivotally attached to the second tow bar segment at a second hinge that defines a second axis parallel to the first axis; an accessory connection attached to the first tow bar segment, the accessory connection provides for attachment to the motorized utility cart; a clamp attached to the third segment, the clamp for attachment to the shopping cart; and a ball joint that permits the clamp to articulate with respect to the second hinge.

A hitch system for distributing weight from a trailer to the wheels of a towing vehicle. The system has a hitch head that is pivotally connected to a hitch bar and is pivotable about a hitch head axis with respect to the hitch bar. A hitch pin is rotatably fixed to the hitch head and the hitch pin is rotatable with respect to the hitch head about a hitch pin axis. The hitch pin axis is transverse to the hitch head axis. A single spring is pivotally connected to the hitch head and is pivotable with respect to the hitch head about a spring axis. A distal end of the spring spaced from the spring axis is connectable to the trailer when the trailer is connected to the hitch pin and the spring can provide a biasing force when the distal end of the spring is moved nearer the trailer.

A support assembly for a trailered implement includes an implement support link that is moveable between an implement support position and a stowed position, and a shaft support link that is coupled to the implement support link via an intermediate link. The shaft support link is moveable between a first support position and a second support position. When the implement support link is disposed in the implement support position, the shaft support link may be disposed in the first support position to support and position the rotatable shaft at a first height relative to a ground surface. When the implement support link is disposed in the stowed position, the shaft support link may be disposed in the second support position to support and position the rotatable shaft at a second, lower height relative to the ground surface.
