Pressure wheel
-
The pressure wheels provide depth guidance when storing the seed, cover the seed with fine soil
and press it against the seed.
-
To sow all coulters to the same depth, it is necessary to have the wheels set in the same position.
Settings
-
For each short coulter, it is possible to adjust the position of the pressure wheel relative to the
coulter disc.
-
If you want to have a different sowing depth between neighbour rows you must change the position
of the link wheel.
Example:
On seed coulters with adjustable pressure wheels (short) it is possible to adjust the
sowing depth to the long seed coulter (6 cm long, short 4)
