3. Move the scraper as close as possible towards the press roller (approx. 2 mm
distance). Rotate the press roller and check for free rotation during this pro-
cess. The scraper should not rub against the (clean) press roller at any point.
6.2.2.6 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. It should
then be removed.
NOTE
Ø
To avoid damaging the uniformers do not reverse with the machine lowered.
6.2.2.7 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.
1. Loosen the front screw (B).
2. Remove the screw from the rear position (C).
3. Fasten the press roller again in the front position (D).
4. Tighten both screws with 100 Nm.
NOTE
Ø Set the press roller to the upper position for deep seed placement. This aligns
the coulter horizontally.
