being created in front of the leveling bar should be even across the entire
working width.
The piston rod end of the master cylinder should never be extended more
than 30mm (50mm for the slave cylinders) Be sure to tighten all lock-
nuts.
Make a habit of bleeding out the cylinders each time the harrow is
attached to the tractor, before work, as well as a few times during the
working day.
Adjusting the levelling bar.
In the field, when the harrow is lowered into working position.
First, the system must be bled, in the same way as the support
wheels.
Adjust the piston rods (pos. 1) so that the levelling bars are aligned.
The levelling bar on the middle section may need to be adjusted 5-
10mm lower, in order to eradicate the wheel tracks. When the
1
piston rod end is extended, the leveling bar is raised, and vice versa.
Do not extend the piston rod end more than 20mm.
Make a habit of bleeding out the hydraulic system each time the
harrow is attached to the tractor, before work, as well as a few times
during the working day. It only takes about 15 seconds.
Depth adjustment of the harrow
B
A
The depth adjustment is performed by adjusting
the sensor "A" out (smaller working width) or in
(bigger working depth) Loosen the thumbscrew
"B", move the sensor arm "C" to the right
position and tighten the thumbscrew "B" again.
When the sensor activator "D" meets the sensor
"A", the valve "E" will cut off for the return oil
and the harrow depth will be locked. By means
D
of the on/off switch in the cabin, the depth
adjustment can be "oversteered". That is to say
C
that the sensor activator "D" can pass the sensor
"A" and a deeper work is possible e.g. on the
E
headland.
