Abstract
A self-leveling cross-country vehicle is provided with a carrier frame which is pivotally mounted to the vehicle frame about the longitudinal and transverse axes. Hydraulic cylinders are connected to each side of the mounting shafts of the carrier frame which are connected to a hydraulic pressure circuit. The wheels of the vehicle are mounted on axles which is provided with a hydraulic piston also connected to the hydraulic pressure circuit. The up and down movement of the axles as the vehicle travels over the ground actuates the hydraulic piston which levels the carrier frame with respect to the ground.
