A cultivator wing raising machinery contains a hydraulic cylinder and a wheeled lever. The wheeled lever is welded from one side to a tube located in semi-cylinders bowed from a sheet material and bolted together, those cover the tube and form plain bearing housings welded to transverse beams of thecultivator wing frame and containing thrusts for axial tube displacement restriction. From the other side, where a bushing is welded, it is connected to a transport wheel axle. At that the hydraulic cylinder rod is connected to the bracket welded on the tube, and the hydraulic cylinder driving a wheel lever is connected with the bracket, welded to the transverse beam of cultivator wing frame, on which a tillage depth regulating mechanism is immovably placed that has a thrust, a regulation screw and a locknut.
