PRESSURE RELIEF AND COLLISION LOCK
Caution!
Only open the
linch pin when
the spring is not
under tension.
Mechanical pressure relief of the mower units (SELECT Control)
The contact weight of the mower units is reduced in the
“Select Control” version by way of an adjustable spring
pressure relief.
Adjustment:
To change the setting, raise the mower unit until the pressure
relief springs are depressurised, peg the linch pin (A) in one
of the 2 possible positions and secure. The linch pin may
be rotated through 180° (P2) for intermediate settings.
Note:
Pegging position (P1 and P2) is the
minimum pressure relief and cannot be
adjusted!

Collision lock:
An adjustable counterpressure is generated hydraulically
for the collision lock. The mower unit swings back slightly if
this is exceeded. Return swivelling to the working position
takes place automatically.
Adjust pressure (X) in hydraulic cylinder:
- Depressurize control valve on tractor.
- Connect plug-in coupling (St) on tractor and on mower
combination.
- Open shut-off valve (Ab) (position E).
- Activate control valve on tractor until working pressure
is reached -> see pressure gauge (Ma) display
Collision lock: Working pressure (x): 110 bar
- Close shut-off valve (Ab) (position A).
- Disconnect plug-in coupling (St).

Caution!
The machine can-
not be brought
into the transport
position if there
is no pressure in
the pressure relief
system.
Caution!
No-one may re-
main within range
of the machine
during the adjust-
ment process.
The mower units
can pivot slightly
forwards. Danger
of crushing!
Note:
Maintenance
of
hydraulic Pressu-
re relief: Reduce
the relief pressure
prior to lubrica-
ting the cylinder
mountings to
ensure even lubri-
cation.
