5.5.8 Baffle plate (optional)
When working on sloping terrain, the seed may
shift inside the singling unit. In this case,
individual holes on the drum or entire rows are
no longer supplied with seed.
Baffle plates (Fig. 72/1) help to prevent the seed
from slipping in the fluid bed.

5.5.9 Blower fan for seed singling
The fan (Fig. 73/1) generates the air current for
seed singling (Fig. 73/2).
The fan hydraulic motor is driven by the tractor
hydraulic system.
The fan speed is adjusted on the flow control
valve of the tractor.
The fan speed is properly adjusted when the
AMATRON 3 displays an air pressure of 55 mbar
in the singling unit.
The air pressure in the singling housing is
measured by a pressure sensor (Fig. 74/1).
To prevent the seed grains from falling from the
singling drum, the air pressure must be kept
constant in the singling housing.
The required air pressure is built up

when all of the holes in the singling drum
are occupied with seed grains.

when maintaining a constant fan speed.

when the system is properly sealed
(pressure tank).
The AMATRON 3 issues an alarm if holes in the
singling drum are not occupied by seed grains.
The alarm is triggered if no seed is detected by
the opto-sensors.
