perform hydraulic adjustment by pressurizing the cylinder [A] from the tractor cab, which
extends the cylinder. Then, put on the required number of stops [B] and pressurize the
cylinder

again to slide it back to the stops
[B]
. Through this, you can raise or lower the
rear roller of the machine. Secure the cylinder [A] against dropping down with the lever
[C] .
•
when adjusting the working depth with the cylinder, keep in mind the parallel position of
the machine frame during operation. Lower the machine correctly on the tractor three-
point linkage/hitch.
•
if required, repeat the steps above several times to obtain the desired working depth.

after setting the working depth, you can begin adjustment of the disc harrow.
If the adjustment range does not match the actual field conditions, you can change it by varying
the cylinder length:
•
remove the nut and pull out the bolt [D]. Caution: the cylinder tip can be
released freely, endangering your health, so support or suspend it
•
extend the cylinder to its extreme position [A] by applying pressure to it
