A vehicle for supporting a crop picking head attached to a self-propelled harvester during over-the-road transportation in order to reduce the load on the wheels of the harvester in order to meet regulatory requirements. The vehicle is attached to the crop picking head in preparation for road travel and detached before harvesting a field. The vehicle features a mount and at least one wheel supported downward from the mount. Furthermore, the wheel is suspended from the mount through a spring element capable of absorbing irregularities in the road surface. Preferably the spring element is a hydraulic cylinder connected to a pressure reservoir, wherein the pressure reservoir operates independently of the harvester's hydraulic system, provides damping for the hydraulic cylinder, and may be set at various pressures based on the load and road conditions.
A vehicle for supporting a crop picking head of a self-propelled harvester during road use, the vehicle comprising a mounting frame having front and rear ends, at least one wheel extending downward from the frame, the frame including latches configured to removably attach to the crop picking head mounted to the harvester, the wheel being suspended near the front end of frame through a spring element, the spring element having a hydraulic cylinder including a pressure chamber connected to a pressure reservoir such that the pressure chamber forms a closed system with the pressure reservoir;
