Central Seed Supply – seed always available when it is needed

Seed is delivered from the central hopper to the reception units above each sowing unit via an air stream. These reception units act as a small intermediate store for seed. The air stream stops automatically when the unit is full enough so that the internal colour-coded sieve is covered by seed. This also means that no more seed is conveyed from the central hopper to the sowing units. The air stream starts automatically when the amount of seed in each intermediate store has fallen sufficiently and the sieve can be seen again. Delivery of seed from the central hopper to the sowing unit restarts at this point. The Central Seed Supply System means that each row is constantly kept supplied with seed without the need for any electronic control.
