Setting the placement depth of the seed
One of the most important preconditions for high yields is maintaining
a constant placement depth of the seed.
The placement depth depends on coulter pressure, forward speed
and soil condition. Your seed drill is equipped as standard with a cen-
tral coulter pressure adjustment which applies an even pressure to all
coulters.
Check the seed placement depth always:
•
before starting to drill
•
after every coulter pressure adjustment
•
after re-adjustment of the RoTeC+ depth limiting discs
•
when changing the forward speed
•
in changing soil conditions.
Travel with your seed drill in the field approx. 30 m at operational
speed, check the placement depth of the seed and readjust if
necessary.

Hydraulikzylindern betätigt.
The central coulter pressure adjustment is actu-
ated with hydraulic rams.
If the soil is changing from normal to heavy or
vice versa, with the aid of the hydraulic rams the
coulter pressure can be adapted to the soil dur-
ing operation.

Important!
The hydraulic coulter pressure adjustment is coupled with the
hydraulic extra coverage following harrow adjustment (if exist-
ing). If the coulter pressure is increased, the extra coverage fol-
lowing harrow pressure will be increased automatically.
Warning!
Actuate the control spool valves only from the tractor cab.
When actuating the control spool valves several hydraulic rams
may start actuation simultaneously, depending the switching
position.
Advise people to leave the danger area.
Danger of injury from moving parts!
