Structure and function
The plastic disc can be fitted in three positions or
it can be removed to limit the seed placement
depth (Fig. 80/1 - 4).
The plastic disc can be adjusted or removed
without the need for tools by using the handle
(Fig. 78/5).

Coulter pressure
The seed planting depth depends on three factors
•
the condition of the soil
•
the coulter pressure
•
the travel speed
With the hydr. coulter pressure adjustment, the
coulter pressure can be preset for two types of
soil. This means that the coulter pressure can be
adjusted to the soil during the work, e.g. in event
of a change from normal soil to heavy soil and
vice versa.
Two pins (Fig. 81/1) in an adjusting segment limit
the hydraulic cylinder. With increased coulter
pressure, the stop (Fig. 81/2) of the hydraulic
cylinder is at the top pin.
The numbers on the scale (Fig. 81/3) are provid-
ed for guidance. The higher the number, the
greater the coulter pressure.
The foldable machines are equipped with two
adjusting segments.
