DANGER
Before carrying out maintenance regarding cutting
blades put the machine in a safety position (see “6.2
Machine in safety position” ).
When servicing or replacing blades with the lifted ma -
chine, put stands under the machine. Prevent risk of
being crushed if the machine falls.
The blades fitted on the implement are suitable for soil of a
normal consistency. If the blades should accidentally bend
(or break) during work, they must be immediately replaced.
Make sure that the new blades are mounted in exactly the
same positions as the old ones. If several blades must be
replaced, it is advisable to demount and remount them one
at a time in order to avoid positioning errors. The sharp side
of the blades must point towards the direction in which the
blade rotor turns.
To replace blades, put the machine in a safety position (see
“6.2 Machine in safety position”):
• Unhitch the machine from the tractor (see “5.6.15 Unhi -
tching the machine from the tractor”).
•
Lift the machine (see “3.2 Handling”).
•
Put two bearing stands at the sides of the machine (for
machine weight, see “3.2 Handling”). Place the machine
on the stands. Do not remove the lifting hook.
•
Place yourself under the machine.
•
Remove the collar clamp.
•
Loosen the two bolts (2, “Fig. 37”).
•
Remove the block (1).
•
Remove the blade (3) sidewards.
•
Replace the worn blade with a new one.

To fit back the blade do the same procedure in reverse or -
der.
NOTE
THE BLADES ARE RIGHT AND LEFT. CHECK THE DIRECTION OF
ROTATON OF THE ROTOR AND FIT THE BLADES PROPERLY.
TO REMOVE THE OTHER BLADE BRING IT TO THE OPENING
WHERE THE COLLAR CLAMP IS TIGHTENED. INSERT A LEVER
BETWEEN THE TWO BLADES. ROTATE FORCEFULLY UNTIL YOU
BRING THE BLOCK OF THE OTHER BLADE IN FRONT OF THE
OPENING, ON THE ROTOR.
CAUTION
Danger of falling. When rotating the rotor with a lever,
the blades could hit the stands. Leave the machine
hitched to the lifting hook. Proceed carefully and plan
all the working phases.
CAUTION
The bolts that holding the tools must have their heads
on the side of the tool, and the nut on the side of the
support. Comply the driving torque value.
