Abstract: An agricultural implement is described comprising a chassis, a rotor mounted thereon that is rotatable about an upright axis and comprises working tools, a hydraulic lifting device for raising the chassis between a work position and a transport position, and an adjustment mechanism for adjusting the height of the rotor for the work position. The lifting device is arranged underneath the rotor and is connected to a hydraulic line that is run from top to bottom through the rotor. The adjustment mechanism comprising a tubular actuating element surrounding the hydraulic line or forming sections thereof with at least one axial adjustment thread mutually supporting the rotor and the chassis and an operating device arranged above the rotor for axially turning the actuating element.
