5.20.1 Seed placement depth
The seed placement depth depends on different factors, such as the
ï‚· Soil type (light to heavy, dry to wet)
ï‚· Forward speed
ï‚· Position of the depth limiting discs
ï‚· coulter pressure
ï‚· Condition of the seedbed.
The adjust the seed placement depth, the depth
limiting disc can be moved to the desired po-
sition or removed.
The plastic disc can be adjusted or removed
without the need for tools by using the handle
(Fig. 80/3).
The "Control 10" depth limiting disc
(Fig. 82/1)
ï‚· limits the set seed placement depth
ï‚· cleans the rear side of the seeding disc
ï‚· improves the drive of the seeding disc by
gripping the soil.

The "Control 25" depth limiting roller
(Fig. 83)
ï‚· permits shallow seeding, even on very light
soils, thanks to the wider tread surface.
