ABSTRACT:
The invention concerns an arrangement for the movement of a working unit of an agricultural working implement between a first position and a second position, with an actuator that is provided with a chamber to which a pressurized medium can be applied and that is coupled to the working unit in such a way that it brings the working unit into the second position when the medium is applied to the chamber and the working unit reaches the first position when the medium is not applied to the chamber. An accumulator control arrangement serves to connect the chamber of the actuator to the accumulator only when the working unit moves into the first position.
