<p>The system has pivot flaps attached to distributer heads of an agricultural pneumatic seeder for periodically blocking seed supply to outlet connection pieces, which are attached to tramline colters. The pivot flaps produce a signal representing a closing-or opening position of the pivot flaps. A signal transmission device (11) transmits the signal to an evaluation- and display device. Sensors are designed as reed switches (8) and attached to the pivot flaps. The signal transmission device is designed as a common signal line i.e. data bus line.</p> |
