NOTE
¾
Set the press roller to the upper position for
deep seed placement.
This aligns the coulter horizontally.
If depth guidance by the press rollers cannot be
assured on soft and sandy soils, these can be
replaced by press rollers with a width of 7.5 cm
(option).
Rubber mounting
NOTE
¾
Keep the rubber mounting free of oil.
Oils and grease can harm the rubber and thus
adversely affect the function.
