Roller for sowing small seed
The rollers for sowing small seeds comprise
metering discs, spacers and drive shaft.
In order to prevent problems when sowing small
seed, the metering rollers are completely pre-
assembled in the factory.

The rollers can be fitted with one or two meter-
ing wheels.
Two metering wheels on a roller will double the
delivery rate.
Metering discs are available with a delivery rate
of 3.5 cm³, 5 cm³ and 10 cm³.
When sowing is in progress, only the metering
wheels rotate in the roller. The spacers are pre-
vented from turning by stops on the housing.
Checking rubber sealing strip
A defective sealing strip or incorrectly
fitted support plate will lead to metering
errors when sowing.
The sealing strip must not be torn or damaged,
replace if necessary.
Fit the side cover with sealing strip to the me-
tering unit housing. The rubber sealing strip
must make good contact with the roller.
Sealing strip
The mounting plate for the sealing strip is divided
asymmetrically.
The broad side must be towards the
roller for all normal and small seeds.
For large seed, like maize, beans, etc.,
the narrow side must be towards the
roller.
