A device for controlling automatically the insertion of plant material in a shredder (1) provided with an internal-combustion engine (2), comprising a sensor which is adapted to send a signal which is proportional to the supply of the internal-combustion engine to a control unit (8) which is adapted to process the signal by comparison with a preset value and to consequently transmit a pulse to an electric valve (10) which is capable of sending selectively oil to the hydraulic motor (4) of the feeder roller (3) for the material to be shredded, and directly to the discharge. |
