| Zusammenfassung: | The harvested or cut off plant parts are lifted from the soil and guided through the gap (25) between a rotating drum (10) equipped with chopping blades (13) around is outer surface and a self-adjusting counter blade (8). The position of the blade (8) is monitored by two sensors (35) registering the vibrations in order to determine a potential movement towards the rotating blades (13) and transmitting the information to a processing and control device (38). Both elements (35) can be used as transmitters and receivers in order to avoid a complete breakdown of the system when a sensor (35) fails. |
