ATTACHING TO TRACTOR
Note:
Hydraulic
relief
maintenance:
Prior to lubricat-
ing the cylinder
suspension,
reduce the relief
pressure to 0 bar
to ensure even
lubrication.
Note:
A hydraulic upper link is recommended
(Dual-acting servo)
Set hydraulic relief
Relief system control
1. Set the right lower link pin at the correct ground clearance.
Arrowheads point to each other. (see "Attaching
implement to tractor")
2. Move single-acting servo to "Float" position.
3. Check the bearing pressure:
by lifting the cutter bar on one side. The weight
on the cutter bar, inside and outside, should
be 75 kg.

75 kg
Setting the relief
1. Adjust the 3-way-valve on the headstock up to set the
"Hydraulic relief" function .
2. Activate dual-acting servo
3. Read the preload pressure on the manometer.
Repeat steps 2 and 3 until the required pressure can
be read on the manometer.
4. Close the 3-way-valve on the headstock (move to middle
position)
- Reference values for preload pressure ex works:
Display value on manometer
for machine without conditioner:
110 bar
for machine with conditioner:
145 - 150 bar
Note:
Note that the
degree of dirt
accumulation
affects the ground
pressure of the
machine.
- Set the right lower link.
1. Put the mower unit in "floating" position using the
single-acting servo
2. Move the lifting gear in the appropriate direction until
the indicator arrow points (1) on the relief cylinder
point directly at each other.
This setting means an approx. 700 mm
ground clearance to the right lower linkage bolt.

2. Activate dual-acting servo on tractor until the mounting
frame is horizontal.
Adjust upper link
- Turning upper link spindle (16) adjusts the cutting height.
Note:
The mower is to be swivelled into field
transport position!
Note:
The
hydraulic
connection for the

the mower is fitted
with a stop valve.
Open this prior
to changing the
preload pressure
and close it again
after changing the
pressure!
