Levelling unit
The following components act as levelling ele-
ments:
A concave disc arrangement or
A spring tine arrangement.
Concave
discs
The discs mix, crumble and level out the earth.
The bearings of the concave discs consist of a
two rows of angular-contact ball bearings with
slip ring seal and oil filling and are maintenance-
free.
The discs are protected against overload by rub-
ber spring elements. After passing an obstacle,
the discs are moved back to their working posi-
tion by the rubber spring elements.

As an alternative to smooth discs, the implement
can also be equipped with serrated discs.

Spring
tines
The spring tines level the soil.
The spring tines are protected against overload
by spring steel. After passing an obstacle, the
spring tines are moved back to their working
position.

adjustment
The working depth of the levelling unit is set in-
dependently of the working depth of the tines.
For information on setting the working depth, see
