SAFETY WARNING
If the discs stop and block up because of incorrect pre-tension, too loose soil or wear, the seed will
be placed in bunches.
When replacing the opener discs, the pretension of both opener discs must be adjusted via the washers.
The opener discs must be slightly pre-tensioned at the cutting edge, but should still be free turning without
using force.
Scrapers, opener discs and press wheels
Attention must also be paid to the function of the scrapers. If these already show signs of wear and a
wear edge has formed, this edge must not touch the cutting edge, because then the automatic
readjustment would no longer work. If necessary insert another washer or replace the scraper.
SAFETY WARNING
Keep the rubber buffers free of oil. Oils and grease can harm the rubber and thus adversely affect
the function.
Seed Firmer
The seed firmer firms the seed in the seedbed and presses it gently down. Under moist conditions and
sticky soils the seed firmer may pick up residues. In this case, it should be removed. To avoid damaging
the seed firmers do not reverse with the machine lowered.
Press Wheels
The press wheels are fastened to the coulter arm with a serrated segment. They guide the depth of the
seed placement, cover the seed with fine soil and press it down on the seed.
A scraper keeps the press wheels free of dirt. The scraper can be readjusted when required.
If depth guidance by the press wheels cannot be assured on soft and sandy soils, they can be replaced
by press wheels with widths of 5.0 cm, 7.5 cm or 10 cm.
