A king pin adaptor is provided for allowing a king pin, intended to connect to a fifth wheel hitch, to be attachable to a ball hitch assembly. A ball hitch assembly is provided having a plurality of vertical and longitudinal positions for securing a ball member to allow for greater flexibility in attaching to various towed structures. The king pin adaptor and ball hitch assembly may be used alone or together as components of a towing system for towing a trailer with a king pin or ball mount.

Disclosed is a detachable receiver apparatus for a hitch assembly. The apparatus includes a body having an attachment portion and a receiver portion. The attachment portion may be selectively attached to a frame of a towing vehicle. The receiver portion may be selectively attached to a receiver member. The receiver member may selectively attach to a hitch bar. In one embodiment, the receiver portion is received within the receiver member. In another embodiment, the receiver portion defines a cavity for receiving the receiver member. The attachment portion may include at least one locking member for selectively locking or unlocking the attachment portion to the frame of the towing vehicle. The assembly may include an actuator for selectively locking and unlocking the locking member.

Adapter (27) of an agricultural implement, having a first, cylindrically contoured section (27a), the external diameter of which is designed to couple the agricultural implement to a US quick-hitch attachment system of an agricultural support vehicle, and having a second, spherically contoured section (27b), the external diameter of which is designed to couple the agricultural implement to a European lower-link attachment system of an agricultural support vehicle.

A fifth wheel hitch has a base attachable to a towing vehicle, a seat attachable at a selected elevation above the base, and a kingpin adapter attachable to a kingpin of a trailer so as to permit rotation of the kingpin adapter relative to the kingpin about a kingpin rotation axis. The seat has a mouth which narrows in the longitudinal direction, such as by having a pyramidal shape. A bottom of the kingpin adapter has a shape which can cause both pivoting rotation of the kingpin adapter relative to the kingpin and longitudinal or transverse translational movement of the kingpin adapter and attached kingpin when the towing vehicle is driven to a position with the seat under the bottom of the kingpin adapter and the kingpin is jacked down so the kingpin adapter seats into the seat. Polymer handgrips on the base facilitate handling of the fifth wheel hitch.

An implement mount for height adjustable mounting of an implement to a vehicle. The mount features a hitch coupler for mating with a single-point hitch of the vehicle to reach longitudinally therefrom, and a guide frame defining at least one guide slot lying transverse to the longitudinal direction of the hitch coupler in an upright orientation. At least one link arm is pivotally supported on the hitch coupler, and an implement carrier is coupled to the link arm proximate a rear end thereof. A follower arrangement is engaged between the link arm and the guide slot to constrain movement of the implement carrier to movement along the guide slot. Pivotal movement of the link arm in a first direction lifts the implement carrier along the guide slot, while pivotal moment in a second direction lowers the implement carrier along the guide slot.

An apparatus for pulling travel trailers is disclosed. The apparatus for pulling a travel trailer includes an extension arm and a frame. One end of the extension arm is connected to a ball coupler, and another end of the extension arm is connected to the frame. The ball coupler is to be rotatably coupled to a gooseneck ball located on a towing truck. The frame includes a hitch ball to be coupled to a hitch ball receptacle from the travel trailer. A pair of mounting arms is extended from the frame, and a pair of clamping brackets is rotatably connected to the pair of mounting arms via a pair of hinges, respectively. The clamping brackets are configured to secure to an A-frame of the travel trailer via a set of pins.

The invention described herein relates to an articulating trailer. The articulating trailer is configured such that it can be used with an automobile and/or an all-terrain vehicle. The articulating trailer may have two or more removable free wheels or skids mounted to it. The wheels (or skids) may be mounted substantially on the sides of the trailer. Alternatively, the wheels (or skids) may be mounted substantially underneath the trailer bed. The articulating trailer is configured with a trailer tongue extension. The trailer tongue extension is configured such that it attaches to the trailer at one or more independent attachment points. A user may release one attachment point of the trailer tongue extension causing the trailer to articulate.

A load-bearing trailer dolly which connects a tongue-type boat, utility or other trailer to a towing tandem trailer and bears weight from the trailer during towing. In a preferred embodiment, the trailer dolly is characterized by an axle mounted on a pair of wheels. A dolly frame height-adjustable trailer hitch centered coaxial above the axle axis and midway point framed dolly plate mount by operation of an adjustable sleeve reducer fastened by pinning and lock. Includes dual connecting adjustable height tongues for attachment to rear end trailer hitches on the tandem towing trailer at which a pair of hitch fasteners for engaging the trailer dolly tongues are attached to the rear of the tandem trailer. The adjustable tongue hitches on trailer dolly will give ability to horizontal level tandem dolly. A shock-absorbing spring is fitted between the axle mount and the dolly frame for cushioning the dolly frame on the axle mount as the trailer is towed behind the towing tandem trailer. In the industry of dollies, the car dolly has no shock-absorbing function, just square axle with hubs for wheels, axle is attached to car dolly frame. There is an option with shock-absorbing mechanism or s non shock-absorbing option.
