Uniformer
The uniformer firms the seed in the seedbed and
presses it gently down.
Under moist conditions and sticky soils the
uniformer may pick up residues. In this case it
should be removed.
NOTE
¾
To avoid damaging the uniformers do not
reverse with the machine lowered.
Press rollers
The press rollers guide the depth of the seed
placement, cover the seed with fine soil and
press it down on the seed.
The height of the press rollers can be set to two
positions.

¾
Set the press roller to the upper position for
deep seed placement.
This aligns the coulter horizontally.
If depth guidance by the press rollers cannot be
assured on soft and sandy soils, these can be
replaced by press rollers with a width of 7.5 cm
(option).
Scrapers
The scrapers keep coulter discs and press roll-
ers free of dirt.
¾
Check the function, wear and readjustment
(scraper for coulter discs) of the scrapers at
regular intervals.
Coulter disc scraper
The scraper features self-adjusting carbide tips
glued to the edges.

Ensure even, slightly angular contact across
the entire range of the coulter disc:

Move the scraper as close as possible to-
wards the press roller (approx. 2 mm dis-

at any point.
