Z = ballast weight
M = weight of the machine.

4.3 DURING WORK

Proceed in the following way after you have correctly hitched the
machine, sat down in the driver's seat of the tractor and started
the tractor engine:
- Position the cutter by means of the hydraulic power lift with the
tools raised about 10-20 cm from the ground.
- Run the engine at a low rate and engage the PTO.
- Engage the forward gear and start work with the PTO at full rate.
Gradually lower the machine until it rests on the ground. This
allows it to adapt to the contours of the soil. o the cont
Do not depress the accelerator pedal in an imprudent way
with the PTO engaged.
- Drive a short distance and check to make sure that the plants
and undergrowth are being cut to the required degree.
- The cutting height is regulated by adjusting the rear roller as
indicated in point "4.3.1 Cut regulation".
Certain factors must be taken into account when choosing the
most suitable cut, i.e.:
- the height of the stalks;
- the quantity and size of any twigs and branches on the ground;
- the ground speed of the tractor;
- optimal cutting height adjustment.
A good cut is obtained at a low ground speed and with the blade
rotor turning at high speed.
The speed of the tractor when the machine is operation must
not exceed 6-8 kph or components could be broken or dam-
aged.
Never swerve sharply or change direction when the machine
is working.
Never ever reverse when the machine is on the ground.
Stones or other sharp objects may be thrown up by the spin-
ning blades during work.
Constantly check to make sure that there are no bystanders,
children or domestic animals within the range of action of
the machine.

4.3.1 CUT REGULATION

Cutting height regulation is a dangerous operation. Wear work
gloves and use suitable tools in a good condition.
Proceed in the following way to adjust the cutting height:
- Park the tractor on a flat surface and hitch the machine then
raise it with the power lift;
- Place two strong stands at the sides of the machine to protect
yourself if it should fall;

- Lower the machine on to the stands, turn off the tractor engine
and apply the parking brake.
The cutting height is established by the position of the bearing
roller on the machine (Fig. 9).
To change the position, slacken off the bolts (1 Fig. 9) on both
sides, then remove them from one side and move the roller either
down or up depending on the required cutting height. Fit the bolts
back in place and repeat the operation on the other side. Now
carefully tighten all the bolts.
A taller cutting height is obtained with the roller in the lower posi-
tion while the cutting height will be shorter when the roller is higher
up. This is because the machine is furthered or neared to or from
the ground.
Once the bearing roller has been adjusted and the machine low-
ered to the ground, adjust the third point of the machine so that it
is parallel to the ground.

4.3.2 SHREDDING DEGREE ADJUSTMENT

Shredding degree adjustment is a dangerous operation. Wear
work gloves and use suitable tools in a good condition.
Proceed in the following way to adjust the shredding degree:
- Park the tractor on a flat surface and hitch the machine then
raise it with the power lift;
- Place two strong stands at the sides of the machine to protect
yourself if it should fall;
- Lower the machine on to the stands, turn off the tractor engine
and apply the parking brake.
Open or close the rear casing (2 Fig. 9) to adjust the degree to
which the plants are shredded. The casing has various positions.
The more it is closed, the finer the plants will be shredded.
To improve the shredding operation, the machine can be equipped
with rear rakes (Fig. 10) which only allow the material to come out
after it has been finely shredded.
This is convenient when pruning residues or other plants that have
not been cut by the machine during its run need to be collected,
since they are kept under the casing and shredded again.
Regulate the harvesting blades by raising or lowering them but do
not allow them to touch the ground. Their adjustment therefore
functions according to the actual ground itself.
If large twigs must be cut, the blades must be kept in a higher
position. Vice versa, they must be set in a lower position if the
twigs are smaller so that the material is held back if it is not cut.

4.3.3 SIDE MOVEMENT

To move the cutter sideways when the machine is equipped with a
hydraulic circuit, insert the two pins at the end of the hose pipes (1
Fig. 8) into the relative unions on the tractor.
Cutter movement will then be controlled from the driver's seat by
means of the levers of the hydraulic valve system of the actual
tractor itself.

4.3.4 USEFUL TIPS

Here are a few useful suggestions on how to resolve some of the
problems that may occur during work.
Cut plants shredded to 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.
