Abstract: Representative implementations of devices and techniques provide a tool bar comprising a structure having a plurality of sections arranged in geometric forms. The geometric forms may change shape to keep a tool that is attached to the structure in a desired position while the tool bar is being used on uneven terrain, such as on a hillside or while the tool bar is rotated or pivoted at an angle with respect to the direction of travel. Changing the shape of the geometric forms can also result in rotating the tool attached to the structure with respect to the tool bar.

Abstract: Representative implementations of devices and techniques provide leveling for a vehicle, such as an overland vehicle. A leveling signal is received by a leveling arrangement coupled to the vehicle at a wheel position. The leveling arrangement rotates a rocker plate with respect to the body of the vehicle, changing a location of a wheel coupled to the rocker plate with respect to the body of the vehicle. In an aspect, the leveling signal is based on a first vehicle sensor signal representing a lateral tilt of the vehicle and/or a second vehicle sensor signal representing a pitch angle of the vehicle.

Abstract: Representative implementations of devices and techniques provide an air assist suspension, for use in a wide range of vehicles and implements having multiple axles (such as agricultural equipment). The air assist suspension uses one or more air bags (e.g., fluid-filled bladders, containers, pistons, and the like) to assist in adjusting the loading of the implement with respect to the multiple axles. In one embodiment, the air assist suspension also uses one or more rocker assemblies, coupled to the air bag(s) and coupled to the axles.

Abstract: Representative implementations of devices and techniques provide a jointed folding arm assembly. Two or more solid links may be pivotally coupled together to form a jointed folding arm. The jointed arm may be pivotally coupled at one end to a load device. The other end of the jointed arm may be pivotally coupled to a tongue arranged to pull the load device. Further, one or more actuators or cylinders may be coupled to the tongue, the jointed arm, and/or the load device and arranged to fold the load device.
