The invention discloses an all-attitude adjustment wheeled tractor. The all-attitude adjustment wheeled tractor comprises an attitude adjustment front driving axle, an attitude adjustment rear drivingaxle and an electrohydraulic control system, wherein the attitude adjustment front driving axle comprises a front driving axle; the front driving axle is connected with a supporting frame through anoscillating axle, and the front driving axle can make relative oscillation with the supporting frame around the oscillating axle; a hydraulic adjustment driving mechanism is arranged between the supporting frame and the front driving axle; and the attitude adjustment rear driving axle comprises a rear axle box, a left hub reduction oscillating mechanism assembly and a right hub reduction mechanismassembly. The all-attitude adjustment wheeled tractor disclosed by the invention is improved on the basis of the overall vehicle axle type structure of a conventional tractor, and has the advantagesthat the scheme is easy to implement; the cost is low; the characteristic of high strength of the overall vehicle axle of the conventional tractor is maintained, so that the all-attitude adjustment wheeled tractor is suitable for operation at hilly and mountains regions under severe working conditions; and actuating elements for controlling overall vehicle attitude adjustment are reduced, so thatcost is low, reliability is high, and the control algorithm is simple.
