By means of turning the spring
(FE) the harrow pressure will be
adjusted:
Higher harrow pressure => Turn
spring clockwise
Lower harrow pressure => Turn
spring anti-clockwise
The nut (MU) must be tightened so
much that the spring (FE) is secu-
red against unintentional adjus-
ting, but a manual adjustment is
possible.
With the single harrow as well as
with the harrow-S In the area of
the drive wheel (66) a short harrow
tine must be fitted to avoid a blo-
cking of the drive wheel.

drive wheel extension (SV) must
be fitted. .
Attention!
It must always be ensured, that
the drive wheel never touches the
harrow during work!
