Structure and function

Levelling unit
The following components act as levelling ele-
ments:
•
A concave disc arrangement or
•
A spring tine arrangement.
•
Concave discs
(1) Double disc
(2) Side disc
(3) Manual depth adjustment, hydraulic as an
alternative
(4) Rubber spring elements
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.
The position of the discs to one-another can be
adjusted to the operating conditions via slotted
holes.
Factory setting: discs are mounted in the bottom
position
•
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.
•
Depth 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
page 88.
