•

Metering rollers
The seed metering units are equipped with ex-
changeable metering rollers. The type of meter-
ing roller depends on
•
the grain size of the seed and
•
the seed rate.
The metering rollers are driven at random
•
with the aid of a star wheel via the Vario
gearbox
•
with the aid of an electric motor (full meter-
ing).
For sowing seeds with particularly big grains,
e.g. large beans, the compartments (Fig. 23/1) of
the coarse metering rollers can be increased by
resetting the wheels and divider plates.
