Star wheel
•
Via the Vario gearbox the star wheel (Fig.
24/1) drives the metering rollers in the seed
metering system
•
Via the star wheel the travelled distance
can be measured AMATRON 3 / AMALOG
+
requires these data to calculate the forward
speed and the worked area (hectare coun-
ter).
•
The star wheel controls the creation of
tramlines. After approx. 5 seconds after the
star wheel has been swivelled upwards,
e.g. when turning at the headlands, the
tramline counter shifts on.

Vario gearbox
Not for full electric metering system!
For setting the seed rate
•
the gearbox setting lever (Fig. 25/2) is
manually adjusted. The higher the scale
figure is, the bigger the seed rate will be.
•
the setting motorstellt (Fig. 25/1) adjusts the
gearbox setting lever l (Fig. 25/2) (option).

Full electric metering system
With the full electric metering system each one
electric motor (Fig. 26/1) drives a metering roller.
The drive rev. speed of the metering roller
•
can infinitely be set via AMATRON 3.
•
determines the seed rate. The higher the
drive rev. speed of the electric motor, the
bigger the relevant seed rate will be.
•
automatically adapts to the changing for-
ward speeds.
The additional seed pre-metering is possible,
e.g. at the headlands. The running time of the
seed pre-metering is settable..
