OPERATION
Rear external valve actuation
Operation_Pic_number:1
External control (lift/lower) of the selected valve
with pushbutton (A).
NOTE:
The valve is operated as long as the pushbut-
ton is pressed.
The rear controls have priority over the selec-
ted settings on the control panel/multi-
function armrest.
The maximum hydraulic oil flow rate is ap-
prox. 30 l/min.
If the stopcock on the standard front power
lift is open (see OPERATION Section 20.2),
external actuation cannot be selected for that
valve.
17.8 Hydraulic connectors
When connecting external hydraulic consumers
(e.g. hay loader), the best results are obtained
by controlling them directly from the tractor, rat-
her than through an additional control unit on the
implement. The working speed of each consu-
mer can be set individually.

NOTE:
It is easier to disconnect a pressurised con-
nector from the implement by switching the
corresponding control unit to floating posi-
tion.
DANGER:
When connecting hydraulic
cylinders and motors, make sure
that all hydraulic hoses are correctly
connected (load pressure side of
cylinder to '+')!
Switching connections causes
functions to be reversed (e.g. lifting
instead of lowering), and may lead to
accidents. After working with the
hydraulic system, lock all the
hydraulic valves!

A = Yellow valve.
B = Blue valve.
C = Red valve.
D = Green valve.
E = Hydraulic trailer brake (optional).
RH = Return line at rear, black colour mar-
kings.

External hydraulic connection
(optional).
With this connection, an implement such as a
harvester can be supplied directly from the hy-
draulic pump.
F = Pump pressure line.
F1 = LS control line (Load Sensing).
NOTE:
Implement must be equipped with Load Sen-
sing control.
Turn tractor off when coupling and uncoup-
ling.
Increasing external control pressure
Operation_Pic_number:1
The adjustment lever can be used to select
between 28 bar (A) and 20 bar (B).
Basic setting is 20 bar.
