4.5 ROLLER HYDRAULIC SYSTEM (Fig. 10)
CAUTION
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
mustbe 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. 10), have an automatic release valve (2 Fig. 10).

MAXIMUM PRESSURE 180 Bar
ALL PIPES ARE THE 1/4" SIZE
1. Roller control cylinders
2. 3/8" gas locking valve
3. Flow divider valve
4. Sheath to protect the hydraulic pipes
A. Roller lowering control oil pipe
B. Roller lifting control oil pipe
4.5.1 SEEDER COUPLING HYDRAULIC SYSTEM (FIG. 11)
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.
