Roller assembly for fine seeds
Maintenance
The function and operability of fine seed rollers
must be checked every day.
¾
There should be no gap between the cell
discs. If the gap is too big, additional shims
must be added.
¾
The cell discs must be light turning. Dressing
or similar materials must not block cell discs
or bearings.
¾
The safety clips must be in place and correctly
assembled to avoid the formation of a gap.
Assembly note
To prevent seed from entering between cell
discs and spacers the cell discs and spacers
are installed with zero clearance shims.
Roller for fine seeds
Rotors for fine seeds
The rollers for fine seeds consist of cell discs,
spacers and drive shaft.
In order to avoid malfunction when sowing
fine seed, the cell rollers are completely pre-
assembled at the factory.
The rollers can be assembled with one or two
cell discs.
The use of two cell discs on the roller doubles
the delivery rate.
Cell discs are available with displacements of
3.5 cm³, 5 cm³, 10 cm³ and 25 cm³.
Only the cell discs in the roller turn while sowing.
The spacers are blocked by stop positions on
the housing.
NOTE
On machines with double fall sluice and 2 seed
boxes you may only use rollers with 2 cell discs.
Otherwise the seed is unevenly distributed to
the two halves.
