Press roller scraper
Move the scraper as close as possible to-

wards the press roller (approx. 2 mm dis-
tance). Rotate the press roller and check for
free rotation during this process. The scraper
should not rub against the (clean) press roller
at any point.

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.

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.
