Smart plus distributor head with single row switching

1. The air flow transports the applied materials up the corrugated stack pipe to the distributor head.
2. Here, they collide with the upper plate and are distributed evenly.
3. When the flap is open, the applied materials are carried by the air stream through the seed pipe into the sowing coulter and then the seed furrow.
4. When the flap is closed, the applied materials are deflected downwards, falling into the funnel and are circulated back into the distributor head. As the rows are closed, the metering unit adjusts its output so that the distributor head does not become blocked.
5. At the deflection point, the air escapes upwards and out through the seed pipe, preventing excess pressure building up.
