4.4.2 REAR CASING ADJUSTMENT
For safety reasons, the machine must work with the rear casing
closed. If you have extreme work condition, you can adjust
the clearance, bearing in mind wich residual risks can occur by
doing this.
"extreme work condition" shall be deemed as follow:
Soil too irregular
Excessive moisture of stubbles
adjust the working height of the machine
Soil adhesion to the inside of the frame due to its moistu-
re
lity to work with rear casing clearance adjusted, observing the
following safety instructions:
Back distance from any obstacle, people, things or ani-
mals, will not be lower by
Lateral distance from any obstacle, people, things or
animals, will not be lower by
4.4.3 USEFUL TIPS
Here are a few useful suggestions on how to resolve some of
the problems that may occur during work.
Cut plants shredded too much
Slightly lift the cutter from the ground, adjusting the
height with the wheels (the blades of the cutter must not
touch the ground).
Increase the ground speed.
Cut plants not shredded enough
Slightly lower the machine towards the ground.
Reduce the ground speed.
Do not work in soil that is too wet.
Make sure that the speed of the tractor's PTO is correct
and at full rate (540 or 1000 rpm, depending on the mo-
del)
Rotor clogged
Soil too wet to work.
Raise the machine from the ground.
Reduce the ground speed.
Do not work where the grass is too tall. If necessary,
remove any material that has built up at the sides of the
rotor to prevent overheating.
The machine jolts over the ground or vibrates
Foreign bodies locked between the knives.
feet
feet
Worn or broken knives.
Rotor misshapen owing to blows from foreign bodies
received during work.
Other faults
The machine fails to work evenly along its width, shred-
ding either too much or too little on one side, for example
on the right: shorten the right link.
Work on hilly ground
It is advisable to proceed «upwards» in the direction of the slope.
Particular attention should be paid since, owing to the nature of
the ground, the stability of the tractor could be compromised
or it could slip sideways.
Winter periods
It is inadvisable to work with the machine during cold periods,
when the temperature drops below 0°C (zero degrees centigra-
de), because the tines become sensibly more fragile. Moreover,
when the weather is cold, the machine must be allowed to idle
for a few minutes with the PTO at half rate so as to allow the
lubricants and transmission components to warm up.
4.5 TOOLS
The hammers/knives with which the machine is equipped are
suitable for work with soil/plants of normal conformation. Check
their condition each day to make sure they are not worn. If they
should accidentally bend (or break) during work, they must be
immediately replaced and mounted in the identical position.

Proceed in the following way to replace the tools:
tched, then raise the machine with the power lift
Insert two strong bearing stands at the sides of the ma-
chine to protect yourself should it fall
engine and apply the parking brake
The hammers or tines must always be replaced in dia-
metrically opposite pairs in order to keep the rotor in a
balanced condition
Proceed as described below to replace worn or broken hammers:
Remove the nut (Fig. 7) of the bolt that fastens the worn
hammer. During the assembly phase, make sure that the
Check the bolts and self-locking nuts for wear and replace
them if necessary.
Proceed as described below to replace worn or broken tines:
Remove the nut (Fig. 7) of the bolt that fastens the worn
tines. Take care to check the positions of the various
components, particularly the spacers (Fig. 7). Make sure
that the new tines and components are assembled in the
same positions.
Check the bolts and self-locking nuts for wear and replace them
if necessary.
