Single grain coulter discs
With their wedge shaped arrangement the coul-
ter discs open the seed channel for the seed
placement.
In order to avoid blockage and uneven wear of
the coulter discs, the coulter discs are screwed
on at the front with slight pre-tension to one
another.
This pre-tension will reduce due to wear and the
discs will no longer have contact.
In this case the discs must be replaced or re-
adjusted:

NOTE

Scrapers
All coulter discs are equipped with scrapers on
either side. These scrapers prevents sticking
and blocking of the coulter discs.
