A mechanism for clamping a drawbar in a receiver hitch uses a clamp pad to engage two adjacent interior surfaces of the receiver hitch tube. The clamp pad presses outwardly on the receiver hitch tube causing the opposing corner of the drawbar to engage the other sides of the receiver hitch tube. The clamp pad is extended and retracted by a shuttle member disposed inside the drawbar tube. The clamp may be self-aligning with respect to the receiver hitch. An adjustment mechanism is described for translating the shuttle member. An extendable pin mechanism may be actuated by the shuttle assembly. A locking mechanism may be provided to prevent an unauthorized person from releasing the clamp pad and the extendable pin.

A trolley that couples to a tow saddle is provided. The trolley includes an upper plate and a lower plate. The upper and lower plate are secured against a rear portion of a tow saddle. One or more support bars are coupled to the upper plate. The bars provide structural support for the upper plate and deflect a chain that transits apertures in the upper plate.

A hitch tightening pin system is designed to attach a draw bar to a hitch receiver tube and prevent relative motion between the draw bar and receiver tube. The pin system has an elongate tapered shoulder bolt that has a larger and smaller outer diameter with a tapered surface extending between the larger and smaller outer diameter. The system includes an expansion sleeve that has arcuate portions. The expansion sleeve can slide onto the smaller outer diameter with the arcuate portions facing the tapered surface. A nut tightens to move the arcuate portions radially outwardly to apply force to the inside surface of a draw bar. The application of force causes the draw bar to be held tightly to the receiver tube and reduce or eliminate looseness or rattling during use.

A trailer includes a trailer bed, a draw bar assembly, and a convertible hitch assembly. The trailer bed includes a platform and one or more sets of two or more wheels. The draw bar assembly is coupled to the trailer bed. The convertible hitch assembly includes a hitch converter coupled to the draw bar assembly. The convertible hitch assembly includes an over-axle hitch coupler insertable into the hitch converter, wherein the over-axle hitch coupler is mated to an over-axle hitch component coupled to a first vehicle. The convertible hitch assembly includes a behind-axle hitch coupler insertable into the hitch converter, wherein the behind-axle hitch coupler is mated to a behind-axle hitch component coupled to at least one of the first vehicle or an additional vehicle.

An agricultural tractor having a component storage system. The storage system including a storage bracket which is attached to the pick-up hitch of the tractor. The storage bracket allows for the storage of components of the pick-up hitch when not in use, e.g. a pick-up hitch hook, a drawbar. As the bracket is attached to the pick-up hitch itself, the components are stored in a convenient location for the tractor operator, to allow for hitch components to be changed in a relatively fast manner.
