摘要： 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.

摘要： A grain cart and foldable auger assembly having an upper auger assembly portion with a discharge portion, a lower auger assembly portion with an intake portion, and a joint that allows the upper auger assembly portion to be moved between operating and transport positions. When in an operating position, the upper auger portion and the lower auger portion are offset from each other by an operating offset angle. The grain cart also has a hitch for allowing the grain cart to be towed. The discharge portion is forward of the hitch when in the operating position. Embodiments of the present invention provide, for example, increased forward and side reach, additional storage capacity of the hopper, increased discharge rate from the hopper, and a more compact transport position.

摘要： A coupling device of the type envisaged between a first vehicle (A) with at least two axes and a second vehicle (B) with at least two axes with the first vehicle (A) arranged to precede the second vehicle (B), in particular for the application to convoys of automatically guided vehicles, includes a hinge coupling section associated with the first vehicle (A) and a drawbar section associated with the second vehicle (B), connected to each other with the possibility of rotation through the relative distal sections. The drawbar section has an arc-shaped guide arranged horizontally in front of the second vehicle (B) to extend from the right side to the left side thereof, a slider sliding along the arc-shaped guide and a telescopic arm integral with one end of the slider and rotatably connected to the other end to the coupling section. The coupling device also advantageously include a steering assistance mechanism suitable for a redundancy of the steering members (S) of the second vehicle (B) by setting a steering angle which is a function of the position of the slider along the arc-shaped guide. The coupling device allows the automatic guide system to control the position and trajectories of the vehicles without any substantial exchange of forces through the device and enters into operation to allow the safe stop of the convoy when there are anomalies in the operation of the automatic guide system.
