CAUTION
Adjustments and operations required to prepare the machine
for work must always be carried out with the machine off and
blocked.
Working in proximity of houses or roads, to always respect
the emergency distances. To always assess that during the
workings, no pauses in the zones of residual dangerousness
of the machine
4.1.1 DRIVELINE
DANGER
The driveline is a mechanical component. When it is operat-
ing 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 drive-
line. If you have doubts about the way it operates, if it is with-
out its shields, worn or broken, replace it with a new drive-
line bearing the “CE” mark.
DANGER
Never modify or adapt the driveline in any way. If this is nec-
essary, contact your nearest Authorized Assistance Center.
Since the driveline spins at high speed, it is balanced during 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 pos-
sible as this will ensure that both the driveline and machine 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. 5).
When the driveline is fully inserted, the play must be at least 4 cm
(B Fig. 5). Contact the Manufacturer’s Technical Service if this is
not possible.
CAUTION
Before engaging the PTO, make sure that its rotation speed
corresponds to the rate for which the machine has been de-
signed (540 or 1000 rpm).
4.1.2 WORK POSITION
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.
4.2 HITCHING TO THE TRACTOR
DANGER
Hitching to the tractor could be a dangerous operation. Take
great care and strictly comply with the instructions.
Proceed in the following way to hitch the machine to the tractor in
the correct way:
- Make sure that you are using a tractor whose configuration suits
the machine in question.
- Make sure that there are no objects, bystanders and/or animals
in the immediate vicinity of the machine and that the PTO is
disengaged.
- Make sure that the machine is in a stable, horizontal position,
then back up the tractor towards the machine.
- Having reached the right position, turn off the tractor engine
then fit the driveline first into the PTO of the machine and then
to the tractor PTO. Make sure that it is firmly locked in position.
- Move the power lift bars near and fit them into the plates. Insert
the plug and lock in place with the supplied split pins.
Since the power lift links of each tractor are a certain length and
have a hole of a certain diameter, you must find the most suit-
able position for the tractor you use by inserting the pins into
the relative holes according to your needs and depending on
the diameter.
- Lock the power lift bars with the relative chains and idlers paral-
lel to the tractor. This must be done to prevent the machine
from swinging sideways.
- Insert the driveline and make sure that it is perfectly locked on
to the tractor PTO. Check that the guard is free to turn. Fix the
driveline shield with the relative chain. Remove the driveline
support (4 Fig. 1) and fix it to the relative hitch on the linkage.
DANGER
Take the utmost care when you insert the driveline. Make sure
that it is firmly locked on to the tractor PTO and on the ma-
chine.
Also comply with the indications in the instruction manual
supplied with each driveline.
Make sure that the driveline shield, fixed with the relative
chains, is free to turn without obstructions.
Also check the protective shields on the tractor and on the
implement.
If some guard is not in perfect working order, it must be im-
mediately replaced with a new guard. It is very important to
ensure that the protective shields on both sides overlap the
driveline ones by at least 5 cm.
- Connect the upper third point and adjust the top link in the cor-
rect way, making sure that the upper surface of the machine is
parallel to the ground. This is very important as parallelism be-
tween the axis of the machine and that of the tractor PTO is
obtained in this way.
The following expressions must be observed to ensure that the
tractor-machine assembly is stable (Fig. 13):
M x s < 0,2T x i + Z (d + i)
M < 0,3T
(prudential value)
Z > {[(M x s)-(0,2T x i)]/(d x i)}
(for calculating the ballast)
where:
i = tractor’s wheelbase
d = horizontal distance between the center of gravity of the
front ballast and the tractor’s front axle
s = horizontal distance between the center of gravity of the
machine and the tractor’s rear axle
T = weight of the tractor in running order
Z = ballast weight
M = weight of the machine.
