The hydro-clip spacer rings act as bottom stops for the harrow depth. If
you wish to make the harrow setting deeper, use more spacer rings and
if you want a shallower setting, use fewer. The hydraulic harrow hoist is
not designed to be operated without a bottom stop, i.e. with continuous
hydraulic depth adjustment, as this will result in an uneven harrowing
depth between the sides. The scales (D) are used to indicate that the
working depth is the same on both sides.
Adjusting the rear levelling board
The mechanically adjustable rear levelling board is an implement that is ex-
clusively designed to level the surface after the harrow tines to create opti-
mum conditions for the use of the rear cross-kill roller.

The harrowing depth is adjusted
incrementally by the "hydro clip"
spacer rings (B), which are mechan-
ically mounted by hand on the har-
row section's raise/lower cylinder on
each side. In total, there are two
cylinders on the machine, and the
same and equal number of spacer
rings must be fitted to each.
.
The hydro-clip spacer rings (C) are
stowed on the scale (D), when not in
use. If no spacer rings are used on
the cylinder, the harrow can go to
the maximum depth. Two types of
hydro-clip are supplied with the
machine with a total of 4x 31.8 mm
and 6x 21.4 mm rings. As the spacer
ring is changed with 10.4 mm on the
cylinder rod, the harrowing depth
changes by 12.1 mm, i.e. the ratio is
1:1.16.
The levelling board
(A) is spring-mounted
and mechanically
depth adjustable via
spindles (B). There
are two spindles per
