A fifth wheel hitch having a base assembly mounted to a bed of a towing vehicle, an intermediate assembly mounted to the base assembly, and a hitch head assembly which reduces or entirely eliminates the need for a lubricant, has jaws with mated, intermeshing teeth, and a locking mechanism which clearly indicates whether or not a kingpin of a fifth wheel trailer is properly connected to the fifth wheel hitch. The fifth wheel hitch is easily uninstalled into separate light-weight modules for re-installation on another towing vehicle.

An adjustable trailer hitch and king pin assembly that may be moved longitudinally to adjust the position and weight distribution of a trailer relative to a truck. The disclosed assembly may allow a trailer to be utilized with various different sized and configured trucks while maximizing the cargo carrying capability and efficiency thereof. In one example, an adjustable trailer hitch is provided having a slidable king pin assembly that may be adjusted forwards or backwards to move the king pin to the desired location relative to the truck and trailer. In another example, a removable king pin may be provided that may be removed and moved to a different location according to the weight and desired weight distribution of a truck and trailer combination.

An engine compartment support arrangement for an agricultural machine includes first and second support rails disposed within an engine compartment, a horizontal platform disposed between the first and second support rails and coupled thereto, and a plurality of engine accessory mounts welded to at least one of the first support rail and the second support rail. The first support rail includes a horizontal portion and an angled portion, wherein a second end of the horizontal portion is aligned with a first end of the angled portion. The second support rail includes a horizontal portion and an angled portion, wherein a second end of the horizontal portion is aligned with a first end of the angled portion.

A front tow extended saddle configured for mounting a vehicle to a towing vehicle and a method of towing a vehicle using the front tow extended saddle are provided. The front tow extended saddle includes front, middle, and rear portions, with the front and rear portions extending along different planes. A protective cover extends along the front tow extended saddle and is supported above the wheels of the towing vehicle.

A cast load cell comprising a load sensing portion integrally cast with a first mounting portion. The load sensing portion has a flexure portion spaced apart from the first mounting portion by a flexure gap. The load sensing portion has at least one sensor cavity above at least a portion of the flexure gap. A second mounting portion is integrally cast with the load sensing portion above the flexure gap. A load sensor is connected to the load sensor portion and positioned within the sensor cavity above a portion of the flexure gap. The first mounting portion, the load sensing portion, and the second mounting portion define an integral, low-profile, weld-free, substantially homogenous unitary cast member.

A reinforcement panel for the floor of a pick-up truck bed. The reinforcement panel is assembled between the floor of the pick-up truck and a fifth wheel cross member. The reinforcement panel includes transversely extending reinforcing or stiffening ribs. The stiffening ribs resist deflection in the area of the gooseneck ball receptacle.

A fifth wheel hitch adjustment arrangement for adjusting a position of a fifth wheel hitch plate along a length of a vehicle frame, the fifth wheel hitch adjustment arrangement including a fifth wheel hitch plate, a support arrangement coupled to the fifth wheel hitch plate such that the fifth wheel hitch plate can be moved between a first position along a length of a vehicle frame and a second position along the length of the vehicle frame that is different than the first position, and a drive assembly adapted to couple to a vehicle frame and coupled to the support arrangement, the drive assembly including a rack-and-pinion arrangement, the rack-and-pinion arrangement including a rack member engaging at least one pinion member, the at least one pinion member engaging the rack member of the support arrangement to move the fifth wheel hitch plate between the first and second positions.

A fifth wheel release arrangement for releasing a trailer from a towing vehicle in response to a trigger signal. The arrangement comprises one or more externally threaded fasteners and one or more pinion nuts comprising internal threads for engaging the external threads on the threaded fasteners, thereby holding the fifth wheel in position with respect to a first bracket attached to a towing vehicle frame, wherein the externally threaded fasteners are arranged to be rotationally fixed when received by the pinion nuts. The pinion nuts further comprise external teeth for engaging a toothed rack, and the rack is movable by an actuator system, in response to the trigger signal, in a direction to rotate the pinion nuts, whereby the externally threaded fasteners are ejected from the pinion nuts upon moving the rack by the actuator system in the direction, thereby releasing the trailer from the towing vehicle.

A fifth wheel hitch may include at least one support frame capable of engaging with a towing vehicle. The fifth wheel hitch may further include a cross-member attached to the support frame and an isolation system operatively coupled with the cross-member. The isolation system may include a beam engaged with the cross-member about a first axis, where rotation of the beam about the first axis is dampened via a cross-member isolator. The isolation system may also include a skid plate engaged with the beam about a second axis, where rotation of the skid plate about the second axis is dampened via a wing isolator.
