Driveline With Automatic Clutch; Combi Machine With Seed Drill; Important; Roller Hydraulic System - breviglieri mekfarmer 120 Utilisation Et Entretien

Never fully tighten the nuts as this eliminates the function of
the springs and clutch itself, to the detriment of the transmis-
sion components.

4.3.2 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 oper-
ate 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.
Do not allow the machine to operate unless it digs into the
soil. When working, do not drive around bends with the ma-
chine in the soil. Do not work in reverse. Always raise the
implement before you change direction or reverse.
During transport or whenever the machine must be lifted,
remember to adjust the power lift of the tractor so that the
machine hoe is not raised more than about 40 cm from the
ground.
Do not drive on the public roads with the machine caked with
soil, grass or other materials that could dirty the road sur-
face or hamper the traffic in any way.
Do not allow the machine to drop violently on to the ground.
Lower it slowly to allow the tines to gradually penetrate into
the soil otherwise all the machine components would be sub-
jected to stress that could lead to breakages.

4.4 COMBI MACHINE WITH SEED DRILL

(Fig. 8-9-10)
While working with power harrow in combination with a seed
drill machine both the pins and tractors linkages must be of
3rd. cat. in all differnet working widths.
Be very careful when coupling the machine with a seeder and in
the case of rear installation of hydraulic or mechanical seeder
couplings.
Each hydraulic seed drill coupling supplied with the machine or
at a later date on the Customer's request, has a serial number
and instruction manual where all the specifications for assembly
and use are given.
In the event however of the seeder coupling being fitted by the
end user, remember to:
- Once the frame has been mounted on the machine, in order to
raise the seed drill with the seeds, the overall weight of the
combination must not exceed the value given in the operation
and maintenance manual.
- Make sure that the seed drill is correctly mounted, that it lifts in
the right way and that nothing interferes with the hydraulic pipes.
- Make sure that the mechanical parts of the seed drill do not inter-
fere with the roller of the machine or with the machine itself.
- Make sure that when you drive along the public roads, there
are no sharp parts that project from the sides of the machine.

- Make sure that the relative signs are clearly visible behind the
combi machine. If this is not the case, proceed as required by
the Highway Code regulations in force in the country where the
machine is used.
When transporting on public highways, the seeder hopper must
always be completely empty.
4.5 ROLLER HYDRAULIC SYSTEM (Fig. 12)
After having carried out the preliminary operations in the
correct way, i.e. hitched to the three points of the tractor and
engaged the driveline, the pipes of the hydraulic circuit must
be connected to the relative hydraulic taps on the tractor in
order to allow the various components of the implement to
operate.
The hydraulic pipes have identification labels that depict:
A) Rear roller lowering.
B) Rear roller lifting.
The two cylinders (1 Fig. 12) have an automatic release valve (2
Fig. 12).

4.5.1 SEEDER COUPLING HYDRAULIC SYSTEM

(FIG. 13-14)
Said system relates to hydraulic seeder coupling (if fitted to the
machine)
After correctly fitting the coupling on the machine, to check correct
lifting operation, connect the coupling hydraulic pipe to the tractor
pickup and pressurise so as to permit operation of the structure
above the machine.
Perform this operation empty, twice or three times, making sure
everything is working properly and that there are no mechanical
or hydraulic impediments. Before performing these operations,
make sure no one is standing near the machine.
Seeder coupling drop is spontaneous if there is no pressure in
the system because the cylinder is single acting.
It features a stop valve in the event of sudden breakage of the
pipe.
