Contemplated are cost reduction and enhanced readiness of parts management related to right and left fenders. A work vehicle includes right and left fenders (16) each having a vertical plate member (18) covering an inner face of a traveling device from an inner side of a vehicle body and a top plate member (19) covering an upper portion of the traveling device (5) from above, wherein the top plate member (19) is configured to be front-rear symmetric, and each of the vertical plate member (18) and the top plate member (19) is configured to act as a right-left interchangeable member.

Hitch mounted robot systems and methods for operating the same are disclosed. A hitch mounted robot system includes a coupling mechanism that is insertable into a hitch receiver on a vehicle and a height adjustment mechanism coupled to the coupling mechanism. The height adjustment mechanism automatically moves the coupling mechanism in a system vertical direction to lift the hitch mounted robot system off a ground surface when the coupling mechanism is inserted into the hitch receiver.

A vertically articulating trailer hitch assembly for use with a vehicle, and particularly for use with an autonomous vehicle. The trailer hitch assembly is pivotally attached to the vehicle frame. The hitch assembly is allowed to swing away from the vehicle frame from a lowered position in which the trailer ball is uncoupled from the hitch coupler of the trailer to a raised position in which the trailer ball is coupled to the hitch coupler. The hitch assembly typically includes a receiver that has a long axis. The vehicle frame has a long axis. When the hitch assembly is in its lowered position, the long axis of the receiver is out of alignment with the long axis of the frame. When the hitch assembly is in its raised position, the long axis of the receiver is aligned with the long axis of the frame.

A vehicle hauling apparatus for hauling a second vehicle with a first vehicle includes: a hitch bar for attaching the apparatus to a hitch receiver; a first rail mounted and arranged vertically to the hitch bar; a second rail mounted and arranged to slide vertically along the first rail; a jacking mechanism connecting the first rail to the second rail so as to lift and lower the second rail; a first element of a pivot attached to the second rail; a wheel cradle in which a tire of the second vehicle may be seated; and a second element of the pivot attached to the wheel cradle; whereby the tire of the second vehicle may be rolled along a ground surface into the wheel cradle while the wheel cradle rests on the ground surface and then be raised into a position for hauling by the jacking mechanism.

A trailer has a frame for lifting, transporting and lowering loads. The trailer is towed by a suitable towing device and includes a lifting device for lifting and lowering the load. Means compatible with the type and weight of the load are coupled with the lifting device. The means are forks in the case of stationary loads such as boxes, or a plane surface in the case of a movable loads. The trailer moves in a stable manner because the lifting device is stably secured on a part of the front side of the trailer and wheels are arranged on either side of the trailer. The trailer has a crossbeam on the rear side, which supports part of the weight of the load once it has been lifted and prepared for travel, and one or more support beams across the width inside the trailer.

The trailer tongue system is provided and includes a trailer frame, an arm support assembly secured to the trailer frame, and a trailer connection arm assembly. When the trailer tongue system is ready for deployment, the hydraulic system support activates. The hydraulic system support permits the arm support assembly to pivot between first position and second position depending on whether the user would like to connect or disconnect a trailer from a power vehicle. The arm support assembly enables the trailer arm of the trailer connection arm assembly to be either raised or lowered depending on whether the user would like to connect or disconnect the trailer.

A tow system tows a vehicle behind another vehicle, typically a motor coach or RV. A drive support unit is connected to the hitch insert and includes a fixed vertical shaft. A movable lift support moves a sliding support post between an up position and a down position parallel to a fixed vertical shaft. A vehicle coupler for selectively connects and disconnects the movable lift support assembly to the secondary vehicle while in the down position, and the vehicle coupler raises the first end of the secondary vehicle when moved to the up position for towing the secondary vehicle behind the primary vehicle. A pivot arm pivots about the sliding support post to further elevate a pintle, which receives a lunette ring therein. The lunette ring extends out of a tow bar, which is secured to the underside of the vehicle being towed.

An axle load monitoring system for a load-transporting motor vehicle having one or more auxiliary axles wherein the monitoring system detects a noncompliant carrying-weight condition when the current gross vehicle weight is more than a prescribed maximum allowable gross vehicle weight assigned thereto and/or the current carrying weight of any primary axle and any designated axle group is more than a prescribed maximum allowable carrying weight assigned thereto. And if the current gross vehicle weight is equal to or less than the prescribed maximum allowable gross vehicle weight and the current center of gravity of the vehicle is in a compliance-manageable range which is established by the monitoring system and specific to the vehicle, the monitoring system recommends auxiliary axle usage that would result in compliance with the prescribed maximum and minimum allowable carrying weight assigned to each of the primary axles, any designated axle group and any utilized auxiliary axle.

The disclosed inventive concept provides a vertically articulating trailer hitch assembly for use with a vehicle, and particularly for use with an autonomous vehicle. The trailer hitch assembly is pivotally attached to the vehicle frame. The hitch assembly is allowed to swing away from the vehicle frame from a lowered position in which the trailer ball is uncoupled from the hitch coupler of the trailer to a raised position in which the trailer ball is coupled to the hitch coupler. The hitch assembly typically includes a receiver that has a long axis. The vehicle frame has a long axis. When the hitch assembly is in its lowered position, the long axis of the receiver is out of alignment with the long axis of the frame. When the hitch assembly is in its raised position, the long axis of the receiver is aligned with the long axis of the frame.

A hydraulic or electric de-thatcher power lift assembly attachment that provides control while de-thatching because it is stable and efficient and can be lifted with ease at any time when dealing with difficult terrain. In an example embodiment, the hydraulic version fits hydraulic equipped tractors. In an alternative embodiment, the device may be used with an electric motor from the tractor, or can have its own dedicated battery for power. A hydraulic or electric lift assembly is also provided for a lawn aerator. The various attachments are designed to replace the standard manual lift lever on standard aerators. The attachments can be used on tractors that have hydraulics built into the tractor or on tractors with an electric motor.
