DANGER
The operator must be seated in the driving seat of the tractor
when the machine is working since only from that position
is he able to act correctly. Before he leaves the driving seat,
the operator must stop the machine, apply the parking brake
and turn off the tractor engine.
4.1.1 DRIVELINE
DANGER
The driveline is a mechanical component. When it is opera-
ting it can be a source of danger to the physical well-being of
those who work with it. Take the greatest care when carrying
out operations that involve the driveline. Carefully read the
instruction manual supplied with the driveline. If you have
doubts about the way it operates, if it is without its shields,
worn or broken, replace it with a new driveline bearing the
"CE" mark.
DANGER
Never modify or adapt the driveline in any way. If this is ne-
cessary, contact your nearest Authorized Assistance Center.
Since the driveline spins at high speed, it is balanced du-
ring the testing phase. Any successive interventions could
therefore lead to lack of balance which could then impair
the functionality of the machine besides that of the actual
driveline itself.
The angle at which the driveline works must be the minimum
possible as this will ensure that both the driveline and ma-
chine are long-lasting.
When the driveline is fully extended, in all work conditions, the
telescopic tubes must overlap to at least 1/3rd of their length
(A Fig. 4).
When the driveline is fully inserted, the play must be at least 2
in. (B Fig. 4).
Contact the Manufacturer's Technical Service if this is not
possible.

Before engaging the PTO, make sure that its rotation
speed corresponds to the rate for which the machine has

4.1.2 DRIVELINE WITH ADJUSTABLE PLATE CLUTCH

The driveline has a safety clutch to protect the transmission
components of the machine against stress and excessive over-
loads.
The clutch is calibrated for medium-duty use. If it slips during
work, all the nuts that hold the springs must be evenly tightened
by half a turn and the operation of the device checked after
about 1/8 mile of work. Repeat the operation if necessary. The
clutch must be adjusted by unscrewing the nuts if it is blocked.
If the clutch still slips even when all the nuts have been
tightened, the friction plates must be changed as they could
be worn or because the springs have become slack.
Never fully tighten the nuts as this eliminates the function of the
springs and clutch itself, to the detriment of the transmission
components.

4.1.3 DRIVELINE WITH AUTOMATIC CLUTCH

On request, the Manufacturer can supply a driveline complete
with automatic clutch calibrated for a medium-duty load. This
clutch cannot be adjusted.
In the event of an overload, the clutch slips and continues to
operate as soon as the obstruction has been passed, without
external intervention. Any clutch servicing operations must be
carried out in the workshop in compliance with the driveline
manufacturer's instructions.

4.1.4 SIDE DRIVELINES

The two side drivelines (7 Fig. 1) transmit drive from the reduc-
tion gear housing/central transmission (16 Fig. 1) to the two side
final drives (14 Fig. 1).Standard supply includes drivelines with
CE marking plus relative shields and chains. They are equipped
with a torque limiter with shear bolt calibrated for a medium
stress. If the implement encounters a particularly resistant ob-
stacle and the bolt shears, it must be replaced with a new one
of the same size and material.
If the side drivelines (7 Fig. 1) are removed, it is very important
to ensure that they are remounted in the same position, i.e.
the fork of the left driveline must be positioned at the same
angle as the right one, otherwise the transmission unit could
