Agricultural trailer implement having two supporting wheels, the wheel-axle carriers of which are articulated on the machine frame so as to be pivotable individually in a vertical pivoting plane about horizontal pivot axes coaxial with one another, are under the preload of a force accumulator in the working position and are pivotable between the working position and a transport position by means of a lifting drive. The force accumulator and the lifting drive are arranged jointly in the region of a first supporting wheel and act on the second supporting wheel indirectly via a pivoting shaft, one end of which is connected to a lever in the effective range of the force accumulator and the lifting drive and the other end of which is connected to the wheel-axle carrier of the second supporting wheel. The wheel-axle carrier of the first supporting wheel is equipped, on its side facing the lever of the pivoting shaft, with an extension, to which movements of the lever of the pivoting shaft can be transmitted. For the simplification of settings, there are as force accumulator a single compensating spring and a coupling member which is under the preload of the latter and which is located between the lever of the pivoting shaft and the extension on the wheel-axle carrier of the first supporting wheel.
