A system for actuating a telescopic actuator that is mechanically connected to a back end of a first trailer of a truck and a front end of a second trailer of the truck is disclosed herein. The system has one or more data processors; and non-transitory machine-readable memory storing instructions executable by the one or more data processors. The instructions when executed by the one or more data processor is configured to determine, using data indicative of a geographical location of the truck, an initiation time at which to initiate actuation of the telescopic actuator. The instructions when executed by the one or more data processors is then configured to automatically initiate actuation of the telescopic actuator at the initiation time.

Power dollies can be used for moving moveable objects such as trailers. A power dolly could include a frame, a mount and a plurality of wheel sets. The mount could couple the power dolly to a moveable object. One or more of the plurality of wheels sets could be powered. The plurality of wheels sets could be separated into a primary wheel set and one or more support wheel sets. The wheels of the primary wheel set could extend farther from the frame that the wheels of the support wheel sets.

A vehicle accessory mounting assembly for mounting a vehicle accessory to a vehicle fame assembly includes first and second support members adapted to couple to the frame assembly, a support assembly that includes first and second portions respectively slidably positionable along a length of the first and second support members and selectively engaging the first and second support members to lock the first and second portions at a selected position along the length of the first and second support members, a center portion having first and second portions, wherein the first and second ends of the center portion are adapted to couple with the first and second portions subsequent to the first and second portions being positioned along the length of the first and second portions, and a vehicle accessory arrangement coupled to the support assembly.

A hitch mount configured to be selectively attached to a vehicle, the vehicle having an under bed hitch mounting system is shown and described. The hitch mount may include at least one transverse member, at least one longitudinal member attached with the at least one transverse member, the at least one longitudinal member including first and second apertures, the first and second apertures of different size, and first and second fastening devices configured to selectively engage the under bed hitch mounting system and the first and second apertures, respectively. The hitch mount may also include first and second biasing members operatively engaged with the first and second fastening, the biasing members applying a load against the under bed hitch mounting system, and first and second handles pivotally and rotatably attached with the first and second fastening devices, the handles having a camming surface configured to engage the first and second biasing members.

An adjustable drawbar for a towed vehicle, such as a trailer, which allows it to be connected to a towing vehicle. It includes a hollow member which is configured with an opening along a surface and slidably receives an extension member. The extension member includes a guide which is dimensioned to be received by the opening. When the extension member is axially rotated in a first direction, the guide is engaged with the hollow member and prevents slidable movement. When the extension member is axially rotated in a second direction, the guide is disengaged from the opening and slidable movement is permitted. In this manner, the length of the drawbar may be adjusted as required, for example, to reduce the overall footprint of the trailer when being stored in a confined area.

A hitch mechanism for a work vehicle configured for operation on slopes. The hitch mechanism couplable to a tether fixed in position up the slope. An arm extends outwardly and upwardly from the work vehicle frame and supports a tether engaging structure couplable to the tether. The arm is mounted to the frame structure beneath the body portion of the work vehicle and extends rearwardly from the frame to support the tether engaging structure rearwardly of the body portion and rearwardly of the ground engaging drive mechanism. The hitch includes a pivot structure coupling the arm to the frame that allows the arm to pivot about a horizontal axis such that the arm is shiftable vertically. A controller receives inputs corresponding to at least one vehicle parameter and is operatively coupled to an actuator for causing the arm to shift in response to changes in the vehicle parameter.

A controlled-flexing trailer hitch system and method to facilitate vehicle-to-trailer attachment and maneuvering by providing a flexible state during attachment, detachment, and low-speed maneuvering of a trailer, and automatic change to a fixed in-line state upon the in-line pulling of the trailer, by providing disengageable spring-return stiffening members and a flexible segmented towing member, where the spring-return stiffening members can be disengaged to allow flexible movement of the flexible towing member, and where, upon commencement of the in-line pulling of the trailer, the spring-return stiffening members engage to place the controlled-flexing trailer hitch into a fixed in-line state.

A hitch mechanism adapted to be attached to a vehicle and support a device includes a hitch receiver adapted to attach to the vehicle and a pair of pull arms. A first end of each pull arm is attached to the hitch receiver and a second end of each pull arm is configured to attach to the device. Each pull arm has an adjustable length and being pivotal horizontally and vertically. The hitch assembly allows a device such as a material spreader to be attached to a vehicle so that the device can be operated in its intended way.
