6.3.10 REPLACING HYDRAULIC SYSTEM TUBES
(OPT)
Operator
CAUTION
Before removing a pipe fitting, a hydraulic pipe or a
part of the hydraulic system, release the pressure in
the circuit.
Injury risk. Do not use your hands for searching hydrau-
lic leaks. Use a piece of cardboard or a piece of wood.
ALWAYS WEAR GOGGLES TO PROTECT YOUR
EYESIGHT
ALWAYS WEAR GLOVES TO PROTECT YOUR HANDS
6.3.11 CHANGING THE ROTATING SPEED OF
THE BLADES
Operator
DANGER
Park the machine on a horizontal and stable surface.
Disengage PTO. Turn off the tractor. Put the parking
brake one. Remove keys from the dashboard.
CAUTION
Danger of hot surfaces. The gearbox can reach very
high temperatures. Wait for the parts and the oil in the
gearbox to cool down.
Dispose of used oil in compliance with the directives of
anti-pollution laws.
NOTE
TAKE CARE NOT TO MISTAKE GEARS AS YOU CANNOT FIT GE-
ARS WITH TORQUES DIFFERENT FROM THE ONES INDICATED
IN THE TABLE.
The tine rotors can spin at various speeds, depending on
the gear pairs mounted in the gearbox. It also allows the
soil to be broken up to various degrees depending on its
nature, the amount of moisture it contains, the ground spe-
ed, etc.
Only use the pairs indicated in the table:
GEARBOXES - PTO 540 RPM
A (PTO) 38
B 23
Speed (RPM) 430
54
37 36 27 34
24 25 34 27
402 375 207 328
GEARBOXES - PTO 1000 RPM
A (PTO)
B
Speed (RPM)
The faster the rotors spin, the more the soil is crumbled,
but tractor power draw and blade wear will also be greater.
You are advised to use the lowest rotation speed able to
work the soil in the required way.
To change speed of the blades do as follows:
• Remove the guard of the rear PTO.
• Loosen screws (5, "Fig. 39"). Remove the cap (6).
• Take out the gears from the shafts.
• Exchange the two gears or insert another couple of ge-
ars.
• Fit back the cap (6). Tighten bolts and nuts.
• Fit back the PTO guard.

1.9.1 CHECK/CHANGE OIL IN THE
GEARBOX
Operator
To check the oil level in the gearbox loosen the filler cap with
dipstick (3, "Fig. 39"). Check the level with the dipstick. If
necessary fill with oil up to the right level.
To change oil:
• Place a basin under the oil drain plug (1).
• Loosen the oil drain plug.
• Loosen the level indicator cap (3). Drain all the oil con-
tained in the gearbox.
• Tighten the oil drain plug (1).
• Fill the gearbox with oil.
• Fill with oil up to level.
• Tighten the level indicator cap (3).
For the type of oil to use see paragraph "6.4.2 Recommen-
28
ded lubricants".
