4.10 - SUSPENDED CAB
Cab suspension flexibility can be adjusted depending on
different comfort requirements (road or field work).
Adjustment Fig. 32:
• Road position (trailer symbol on the switch):
- Put the switch (16) in position (1) to make the suspen-
sion stiffer.
• Field position (plough symbol on the switch):
- Put the switch (16) in position (2) to make the suspen-
sion smoother.
Maintenance: see paragraph 5.16.2.
4.11 - FRONT PTO
4.11.1 - Front power take-off
The front PTO is controlled by the switch Ref.1 - Fig. 33
To engage PTO, slide the red safety slider in the direction
indicated by the arrow, while pressing the switch (ref. D) in
order to unlock it.
Push as shown by Ref. E to stop the PTO.
4.12 - REAR PTO
4.12.1 - Selecting PTO speed
The PTO can be engaged and disengaged independently of
the transmission.
To engage PTO, a PTO speed must be selected first.
Therefore, 540 rpm, 540E rpm or 1000 rpm speeds (de-
pending on option) can be obtained by selecting the suita-
ble speed with the corresponding key (Fig. 34).
IMPORTANT: To avoid damaging implements driven
by the PTO, the engine speeds on the above table must
be complied with.
