4.5 ROLLER HYDRAULIC SYSTEM

After having carried out the preliminary operations in the correct way, i.e. hitched to the three points of the tractor and en-
gaged 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).
KEY to Fig. 10 (Hydraulic layout showing roller adjustmentwith two hydraulic cylinders)
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

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
