A device for controlling an outlet flap of a baler in at least one manual and one automatic mode includes an outlet flap drive, a first and a second pressure line via which the outlet flap drive is selectively charged with pressure, a first pressure measuring apparatus operatively connected to the first pressure line, and a second pressure measuring apparatus operatively connected to the second pressure line. A distributor valve is connected to the first and second pressure lines downstream of the first and second pressure measuring apparatus. The distributor valve is disposable in a first pass-through position, a second pass-through position, and a shut-off position. In an automatic mode, the distributor valve is disposed in a predetermined position dependent on a pressure difference between the pressures in the first and second pressure lines.
