11.5
CAUTION:
15
Check the ground before mowing: no stones, twigs, roots or foreign
bodies.
When mowing, keep the engine at full speed and adjust the forward
speed according to the grass height. Be careful and slow down
when coming across tall or dense grass.
Check that the blades are not worn, the cutting edge is sharp and
the blade is not damaged. Sharpen the mower blades frequently;
the cut will be better and the engine will run at lower consumption
( ref.16.4 SHARPENING THE BLADES).
IMPORTANT
Keep the grid in front of the radiator clean (Fig. 1).
To remove it, open the grass-catcher door and release the locking
lever (Fig. 4).
If the grass is wet or very high, do not cut with the mower deck in
the lowest position, but set it to an intermediate position.
Check the PTO driving belt tension
Under normal cutting conditions, the microswitch of the full grass-
catcher should be adjusted to the horizontal position. For optimum
we recommend adjusting it at a downward angle when the grass
is wet or very tall, and at an upward angle when the grass is short
or dry. (Fig. 16)
Check the function of the distributor in the grass-catcher: pressing
the PTO button (Fig. 17) automatically activates the distributor
inside the grass-catcher (Fig. 18).
Check that the blades disengage automatically when the grass-
catcher is full or that the warning buzzer is activated.
(ref. 11.3 MACHINE STARTING, point 10)
At the end of each job, proper cleaning ensures a long service life for the
machine and prevents most common mishaps.
The best way to clean the machine is with compressed air or a blower/
vacuum cleaner.
IMPORTANT:
clean of dust and dried grass residues.
If necessary, use water for the body parts for the mower deck, the load
chute and the grass-catcher; avoid wetting the electrical sensor inside
the cutting height to the minimum, connect the water connection nozzle
(Fig. 14) to the water pipe and let the water run for a few minutes, with
the operator sitting in the driver’s seat
engine running
the advance pedal in NEUTRAL position

Once the work is completed, also clean the grass-catcher grid.
After using water, run the gearboxes for a few minutes, including those
of the mower deck to ensure that all components dry.
CAUTION
area and fuel line clean and free from grass, leaves and dust at all
times.
11.6 Useful rules for proper use
The machine can work even under severe conditions without clogging
issues. A few preventive measures must be taken and all devices must
be correctly adjusted.
Before starting work, check that the mower deck and the load chute
are perfectly clean and free of grass and dirt.
Check that the load chute is correctly positioned and hooked up
16
11.7
Steep terrain should be driven in uphill/downhill direction by paying at-
tention when changing direction and ensuring that the wheels uphill do
not encounter any obstacles (stones, branches, roots, etc.) which could
cause the machine to lose control. If the drive wheels tend to slip, use
the hydraulic control to raise the mower deck slightly in order to put more
weight on the drive wheels and thus gain more drive. Evaluate the vari-
ous situations and be careful on damp ground and wet grass as the ma-
chine may slip. When travelling downhill, start at low speed and avoid
driving over dry or cut grass as the wheels may lose grip.
The can be engaged by pushing the pedal on the left
hand side of the steering column (Fig. 19) in the condition of wheel slip,
or to load the mower on vehicles with ramps. Only engage the differential
lock if necessary.
12 ORDINARY ADJUSTMENTS
12.1 Seat adjustment
Before starting to work, we recommended to adjust the seat where you
are most comfortable and have the most manageability over the ma-
chine. To adjust the seat forwards or backwards, move the lever on the
left-hand side of the seat to the side (Fig. 20/A), then move the seat. To
adjust the inclination of the backrest, turn the knob on the right-hand side
at the base of the seat (Fig. 20/B). To fold the seat up, pull the levers on
the back of the backrest (Fig. 21).
A
B
12.2
To adjust the cutting height, push the button (Fig. 22), pressing upwards to
raise and downwards to lower.
IMPORTANT
1
When working on uneven ground, gutters or bumps, we recommend
working with the cutter deck in the highest cutting position in order to
avoid impact from the blades. There are two anti-scalp wheels at the
positions using the drillings in the deck.
For a proper use, set the height of the wheels at the closest position but
not in contact with the ground.
13 SAFETY DEVICES
13.1 Electronic safeties
On the FD 500, an electronic control unit receives inputs from the mi-
croswitches located on the seat, forward pedal, parking brake and
grass-catcher. Based on these inputs, the control unit produces logical
blocks for the safety of the machine and the operator.
In particular, always remember that:
THE ENGINE
turns off if the operator gets up from the seat with the parking brake
off.
will not start if the driver is not seated in the driving seat, unless the
will not start if the drive pedal is not in the NEUTRAL position.
THE PTO
does not activate if the parking brake is engaged
does not activate if the basket is open or full, unless the warning
buzzer switch has been pressed.
does not activate if the engine is overheated.
13.2
The FD 500 is equipped with a hydraulic feed system. Simply release
the foot pedal to brake. To engage the parking brake, pull the lever with
knob (Fig. 25) and position it in the housing. To release the parking
brake, simply remove the lever from the housing and move it to a lower
position. If the parking brake is engaged and the travel pedal is pressed,
the warning buzzer will sound to warn the operator to release the brake.
The blades cannot be engaged in this condition.
With the parking brake engaged, you can leave the driver’s seat with the
engine running.

CAUTION
Roll-over protection is not ensured if the roll-bar is in the lowered
position.
Do not operate the machine on uneven ground or on slopes with the
roll-bar in the lowered position.
Only lower the roll-bar when absolutely necessary.
Do not wear a seat belt when the roll-bar is lowered.
Drive slowly and carefully.
Raise the roll-bar as soon as clearance permits.
Take care when working under the tree crowns. Check that there
are no low branches or other obstacles that could get in the way of
the roll-bar.

If the parking brake is ineffective, it is possible to adjust it using the ad-
lock nut and unscrewing or screwing the adjusting screw and nut, it is
possible to modify the tension of the wire connected to the lever. The
effectiveness of the brake is due to the block between the two pads of
activated, it is important to have a clearance between the pad and the
disc (0.4÷0.6 mm) and that the wire is not tensed.
