PUTTING THE MACHINE INTO SERVICE
- Make sure the machine is complete and that it has not been damaged during transport.
-Check the levels of the engine oil (fig. 3) and hydrostatic transmission (fig. 4).
-Check the tyre pressures:
Front wheels 23×10.50 – 12 (1.4 bar)
Rear wheels 18×8.50 – 8 (1.4 bar)
- Check the battery voltage, it must not be inferior to 12.5 Volts; recharge if necessary. To get access to the
battery remove the knob of the throttle lever (fig. 5), loosen the dashboard fixing screws and remove the dashboard.
Do not start the machine if the battery is not properly connected or damages to the charge regulator and to the
electronic control modules may occur.
- If a dry battery has been supplied with separate acid, to put the machine into service proceed as follows:
1) pour in the acid and wait 2 hours;
2) charge the battery with a charger set to 12 Volts on a slow charge for 2 hours.
Caution: If this procedure is not followed, acid may leak out of the battery during work and damages to the
battery may occur.
BATTERY
Cau ion! The gases released by the battery are explosive, so keep it away from naked flames or sparks. Check the
level of the li uid at regular intervals and keep the terminals greased.
Impor an :
- Do not invert the battery poles.
- Do not run the lawnmower without the battery, as it is e uipped with a charge regulator.
- Be careful not to cause any short circuits.
RUNNING IN – CAUTION!!
Change the engine oil and filter after the first 50 working hours. Check for oil leaks or loose screws, especially those
fixing the blades and the wheels. Adjust the tension on the PTO belts via the nuts placed on the spring: the spring
has to be adjusted at the length indicated by the red arrow (fig. 6). Adjust the cutting deck belt tension via the nut
placed on the spring: the spring has to be adjusted at the length indicated by the red arrow (fig. 7).
INSTRUCTIONS FOR USE
Before switching the engine on always check that:
-the radiator coolant li uid is up to the level (fig. 8);
-the engine cooling intake grid is clear (fig. 9);
-the engine oil is up to the level (fig. 3);

9) To start work again, disengage the PTO by pushing the switch off and then switch it on again (fig. 1 n°26).
FINISHING WORK
Once mowing has been completed, disengage the blades. To stop:
1) Release the forward pedal (fig. 1 n° 1 or n° 2).
2) Set the throttle lever to the minimum.
3) Lower the cutting deck to the ground
4) Stop the engine by turning the key in the “0” position and engage the parking brake (fig. 1 n° 3 and 5).
GUIDELINES FOR EFFECTIVE USE
The machine can also be used under harsh conditions without any risk of jamming up. Certain measures must be
taken and all devices must be adjusted properly.
1) Before starting work check that the deck and the load chute are perfectly clean without any dried grass or soil.
Check that the load chute has been mounted properly and fixed through the two red safety locks (fig. 13).
2) Check the ground before mowing, that there are no stones, sticks or foreign objects.
3) While mowing keep the engine at maximum rpm, adjust the speed to suit the height of the grass. Be careful
when coming across tall thick clumps of grass, slow down.
4) Regularly sharpen the lawnmower blades; the cut will be better and the engine will not be strained too much.
5) After having emptied the grass from the catcher, always engage the blades some metres before getting into
the grass to cut, so both the cutting deck and grass load chute are cleaned and the clutch is protected.
6) Keep the grid in front of the radiator clean (fig. 9).
7) Keep the grid at the inside of the grass catcher clean: to remove it, insert the grass catcher door safety lock pin
(fig. 12) and use the lever (fig. 11);
8) If the grass is wet or very high, do not cut in the lowest position, but at a mid-way height.
9) Check the tension on the belts activating the PTO; using the adjusting screw if necessary (fig. 6).
10) Check that the blades are not worn, especially the wing that push the grass into the load chute.
11) Under normal cutting conditions, the full grass-catcher micro-switch must be adjusted into horizontal position. It
is recommended to adjust this micro-switch inclined towards the bottom of the grass-catcher in case of wet and/or
very high grass, while it should be inclined towards the upper part of the grass-catcher in case of short and/or dry
grass.
12) Check that no foreign objects have clogged the load chute.
13) Check the rotation of the duct inside the grass catcher.
14) Check that the blades disengage automatically when the grass catcher is full; to do this, turn the ignition key,
turn on the panel without starting the engine, engage the PTO switch (fig. 1 no. 26) and touch the lever fitted on the
duct sensor (fig. 10, ref. A) by hand. The PTO should now disengage.
15) Check the engine revs. (max. 3200 rpm empty).
16) Always mow with the engine at maximum rpm; if the engine rpm drop, reduce the forward speed for a while, to
allow the engine to reach the right level again.
17) Check that the blades are properly mounted.
18) Check that the entry duct fits correctly and that it is aligned inside the load chute.
19) The mower FD900 is a hydrostatic machine and conse uently it will absorb more power when cold, but after a
few minutes its efficiency will be at optimal. We inform you that the variable displacement pump and the hydrostatic
motors are of high uality and efficiency.
20) CAUTION! Do not travel with the cutting deck raised. Only raise it to get over obstacles, mount on pavements
or on kerbs. It is compulsory to travel on public highways with a type-approved machine, fitted with a lighting
system, a nameplate and with the cutting deck raised.

MOWING POSITIONS
Use the button (fig. 1 n° 12) to adjust the cutting height. When working on irregular ground, with bumps or humps, it
is best to use the deck in the highest cutting position to avoid impact with the blade. Important: During work the deck
lifting button has to be in the «floa ing» position and the anti-scalp wheels aligned with the mower deck board.
SLOPES
Steep ground should be tackled in an up-and-down movement, being very careful at direction changes that the
wheels uphill do not meet any obstacles (stones, branches, roots, etc.) which could cause loss of control over the
machine. If the drive wheels tend to slip when driving uphill, use the hydraulic control to slightly raise the deck so
that more weight is exerted on the drive wheels, therefore giving more traction. Evaluate the various conditions and
be careful in the presence of damp ground and wet grass because this could cause the mower to slide. When going
downhill, start off at a slow speed and avoid driving over dry or cut grass because the wheels could lose their grip.
The differential lock (fig. 1 n° 25) is automatically engaged, for example: if during a strong descent you want to
reverse the direction of travel, to avoid the rear wheels skidding or when loading onto a vehicle in reverse using
ramps. Normally do not engage the differential lock button (fig. 1 n° 25). Do not run any risk, check the ground
carefully and if you do not feel safe, avoid strong slopes and do not exceed the speed-limits, which are imposed by
your country laws and written also in this manual (max. 14° or 25%).
SAFETY DEVICES
Always remember that the engine stops each time when:
-the operator gets up from the seat, if the parking brake has not been engaged and the blades have not been
disengaged before.
In addition, the engine will not start if:
-the PTO switch is engaged;
-if there is no one seated on the driving seat, unless the parking brake has been engaged and the blades have
been disengaged before;
-the forward and reverse pedals are not in the “stop” position;
-the grass catcher is not completely lowered.
Attention! When the parking brake is engaged, it is possible to leave the driving seat with the engine on, if the
blades are disengaged.
ROLL-BAR
CAUTION: To avoid injury or dea h from roll-over keep he roll-bar in he raised lock posi ion and use he
sea bel .
Ensure that the seat is secured with the seat latch.
There is no roll-over protection when the roll bar is in the down position.
- Do not operate the machine on uneven ground or on a hill side with the roll-bar in the down position.
- Lower the roll-bar only when absolutely necessary.
- Do not wear the seat belt when the roll-bar is in the down position.
- Drive slowly and carefully.
- Raise the roll-bar as soon as clearance permits.
- Check carefully for overhead clearances (i.e. branches, doorways, electrical wires) before driving under any
objects and do not contact them.
To lower the roll-bar follow the procedure described below:
- Park the machine on a level surface.
- Disengage the PTO, lower the mower deck, and engage the parking brake.
- Shut off the engine and remove the key.

MAINTENANCE AND LUBRICATION
CAUTION!
- Before performing any cleaning, main enance or repair opera ion always wear sui able clo hing and
working gloves.
- When he machine or par of i is lif ed o carry ou main enance opera ions, always remember o use
sui able fixing ools such as holders and safe y locks.
- When carrying ou main enance opera ions and/or when he machine is il ed wi hou safe y locks or
suppor s, never leave i unguarded in places where inexperienced people and children could have easy
access o i .
If you do the maintenance on the engine, keeping the grass-catcher raised engage the two red safety locks on the
hydraulic cylinders (fig. 16). Never work on he engine if you have no engaged he safe y locks.
ACCESSING THE ENGINE BASEMENT
Should the engine not start, to get access to it pull the lever of the hydraulic distributor for the tilting of the grass-
catcher and then push the grass-catcher manually rearwards.
LUBRICATION
Never dispose of used oil, petrol or any other type of pollutant in the environment! Proper maintenance and correct
lubrication help to keep the machine fully efficient.
LUBRICATION CHART
Engine oil 15W40 3 kg Replace after the first 50 working hours and then
every 250 hours.
Coolant li uid / 6 kg Empty and wash the tank then add the coolant
every 1000 working hours or once a year.
Hydraulic oil OSO 46 9,5 kg Replace after the first 500 working hours then every
1000 working hours.
Cutting deck gearboxes LSX 75W90 0,1 kg
0,112 lt
Replace every 300 working hours.
ENGINE
For the lubrication intervals follow the directions given in the engine manual . It is in any case necessary o change
he oil and he fil er af er he firs 50 working hours and hen every 250 hours. For the diesel engine use SAE
15W40 oil uantity 3 litres. When you change the engine oil, it is necessary to change also the oil filter (fig. 3). To
remove the engine oil, unscrew the lid on the right side of the oil cup (fig. 17). Pour in the oil through the lid (fig. 18).
The first precaution to be taken is that the engine is maintained correctly with a clean air filter and the engine oil up
to the level. Keep the engine compartment, the muffler area and the collectors clean. Use a vacuum cleaner if
possible. Check the air filter (fig. 10) and the prefilter every 8 hours. In order not to reduce the air needed to cool the
radiator, the grid must always be kept clear. Make sure the radiator is always clean. The radiator fan is driven by an
electric engine. If the radiator protection grids are clogged and the cooling fluid and the hydraulic oil temperature
gets over 87° C, a sensor automatically reverses the rotation of the fan for a few minutes in order to clean the grids.
To check and clean the radiator fan use the lever (fig. 9).
RADIATOR REFILLING AND PURGE
Cau ion! Danger: hot li uid under pressure. In order to let the engine cool down correctly, there should be no air in
the cooling circuit. Make sure that the clamps on the water muffs are well tight and that no air can get into the circuit
from the outside. Carry out the purge as follows:
Caution: For this operation always wear suitable working gloves.
1) Pour coolant li uid into the expansion tank (fig. 8).
2) Start the engine and bring it to working temperature (to make sure the engine thermostatic valve is open).
3) Re-establish the li uid level in the expansion tank.
HYDRAULIC DISTRIBUTOR for SERVICES
The hydraulic distributor is controlled via levers (fig. 20). Working pressure: 120 BAR.
11

Translation of the original instructions
WHEEL HYDRAULIC MOTORS
Check the level in the reservoir with the motors cold (fig. 4). If more oil is needed, add hydraulic oil OSO 46 (total
uantity: 9,5 litres). Carry out this control fre uently. Cau ion! Replace both the hydraulic oil and the hydraulic filter
of the hydraulic motors after the first 500 working hours and then every 1000 working hours.
The oil has to be changed before the first 500 working hours ONLY if:
-the oil is black;
-the oil has a whitish colour (it is contaminated with water);
-there is black coloured residue (partial oil deterioration).
To drain the oil loosen the pipe on the gear pump (fig. 22). To fill the hydraulic engine again in with fresh oil,
unscrew the upper lid of the tank (fig. 4). Pay attention to impurities, which may obstruct the circuit and damage the
machine. When you change the hydraulic oil, the oil filter must be replaced too (fig. 21). Pay attention to the filtering
grade. Do not increase the pressure of the wheel transmission hydraulic system over 280 bar because this could
damage the hydraulic pump and the hydrostatic motors.
MOWER DECK GEARBOX
Use synthetic oil LSX 75 W 90 (API GL4 + GL5; API MT1 and PG2) uantity 0,112 lt. Replace every 300 working
hours. The gearbox is e uipped with a cap on the right side (fig. 23). To remove oil from the gearbox, you must
disconnect the cutter deck from the machine, remove plastic cover, put the cutter deck in vertical position and
unscrew the lid. Make sure that oil will not get on the belt. (For this kind of operation contact our service centres.) If
the operator notices oil losses, check and replace the seals to avoid damages to the whole gearbox.
HYDRAULIC PRESSURES: summary able
Wheel closed circui (variable displacement pump) 280 BAR
Hydraulic s eering 120 BAR
Dis ribu or 120 BAR. Free, hydraulic steering is
overriding.
Charge pump 7 BAR
LUBRICATION POINTS WITH GREASE
Find the lubrication points following the scheme (fig. 2A, n°4, n°3). Lubricate with grease every 50 hours the rear
axle pivots, the pedals, the PTO transmission belt guide pulley, the pivot connected to 2 points of the cutting deck,
the grass-catcher lifting arms.
EMERGENCY AND PARKING BRAKE
The FD900 moves forward via hydraulic motors. To brake it is therefore sufficient to release the forward and reverse
gear pedals (fig. 1 n° 1 and 2). The brake pedal (fig. 1, n° 3) has to be used only in case of emergency. To engage
the parking brake, press the emergency brake (fig. 1 n° 3) and then engage the locking via the appropriate pedal
(fig. 1 n° 5). To disengage the parking brake just press again the emergency brake (fig. 1 n° 3).
Remember to always engage the parking brake, even though the machine is self-braking when the engine is off.
The engine remains on when the operator gets off the machine if the parking brake is engaged.
ADJUSTMENT OF THE PARKING BRAKE AND EMERGENCY BRAKE PEDAL
The brake adjusting screws are located under the platform (fig. 24). The drum brakes are on the front wheels, make
sure the wire does not touch the wheel.

SHARPENING THE BLADES
To sharpen the blades follow the procedure below:
1) set the cutting deck at the lowest cutting position
2) raise the grass-catcher and remove the load chute between cutting deck and grass-catcher.
3) raise the cutting deck and remove the side pivots (fig. 1, n. 10).
4) Hold the bar on the cutting deck, lean the feet against the bracket and hook the cutting deck (fig. 25). There is
no need to dismount the cardan joint. However before starting the machine, make sure that the cardan joint is well
connected and that the stop push button is protruding.
IMPORTANT: the central screw fixing the right blade disc has a left-hand thread. The tightening tor ue of the
central screw of the blade hub is 53 Nm (assembling scheme – fig. 26) while the screws fixing the blades have a
tightening tor ue of 50 Nm. To make replacement of the blades easier, remove the whole disc.
A blunt blade pulls at the grass giving it an unsightly appearance, the cutting edges of the blades must therefore be
kept sharp at all times. As the blades wear they lose their cutting efficiency and tend to become unbalanced,
causing the mower to vibrate; sharpen both blades uniformly. Cau ion: Always replace damaged or crooked
blades, never ry o repair hem!
CUTTING DECK ADJUSTMENT
An even deck is essential for achieving a uniform cut over the whole lawn. With the mower on a flat surface, check
the tyre pressures, check the distance of the cutting deck edge from the ground and act on the tie rods (fig. 27, A)
and on the adjusting screw (fig. 27, B) to put it parallel to the ground. If a satisfactory parallel set up cannot be
achieved, contact an authorized dealer.
To dismount the cutting deck follow the procedure below:
1) Raise the grass-catcher and remove the load chute.
2) Unscrew the locking screw of the cardan joint cover and unhook the cardan joint pushing on the lock button.
3) Remove the pins from the lifting arm pivots and remove these pivots.
4) Detach the four hydraulic pipes.
5) Pull the cutting deck forward to remove it from the machine.
To mount the cutting deck again follow the same procedure from the last point to the first. Should it be complicated
to connect the hydraulic pipes again, move the lever for the tilting of the grass-catcher, while to connect the cutting
height hydraulic pipes push the cutting height adjustment button with the key inserted in the dashboard.
PTO BELTS
Attention: These belts are special, USE ORIGINAL BELTS.
To replace them, loosen the tie rod (fig. 6) and remove the arm fixed through two screws to the right bracket of the
engine (fig. 28). Unhook the anti-vibration spring of the clutch and the clutch electric wire. To adjust the tension use
a no. 13 spanner on the tensioning spring (fig. 5. n° A). The spring must be compressed at the length indicated by
the red arrow (fig. 6).
ADJUSTMENT OF THE GRASS CATCHER - LOAD CHUTE ALIGNMENT
To achieve best results it is important to have a perfect alignment between the grass catcher and the load chute
when the grass catcher is closed. Follow the points below:
1) Put the grass-catcher in closed position.
2) Shorten or lengthen the rod of the side hydraulic cylinders (fig. 29) for the tilting of the grass-catcher. This
operation can be carried out by unscrewing or screwing the screw set at the bottom of the cylinders rod.
3) This adjustment can also be carried out via the screws fixing the grass-catcher in the rear part (fig. 30).
GRASS CATCHER LOCKING HOOK
The grass catcher locking hook is adjusted via the appropriate screw (fig. 31). Please leave a 2 mm clearance to
make the hooking easier when closing.

5) Please check that the foreign body has not got into the accelerator or the pipe
ELECTRICAL SYSTEM
The electrical system is protected by fuses which, if blown, cause the whole electrical system to cut out. There are
two main fuses, both of 40 A/h: one protects the whole wiring system, while the other protects the fan on the
radiator. The fuses protecting the other electrical components of the machine and the lights are located on the left
mudguard. In case of failure, once he faul y componen has been loca ed and repaired, replace he blown
fuse wi h one of he same ra ing. Never replace a fuse wi h ano her of a differen ra ing. If the electrical
problems still persist even after having changed the fuses, contact the Authorised Service Centre. Never attempt to
carry out complex repairs without having the necessary means and technical knowledge available.
FUNCTIONING OF THE MAIN ELECTRICAL DEVICES
-A safety sensor detects if the grass catcher is in working position (fig. 32), otherwise the cutting deck does not
engage.
-A sensor is mounted on the thermostatic valve of the engine (fig. 33). It detects the coolant li uid temperature.
When the coolant li uid temperature goes over 87°C, the sensor sends a signal to the electronic control unit (fig. 34)
which starts the automatic cleaning cycle, inverting for some seconds the radiator fan rotating sense. It is possible
to carry out the cleaning cycle also manually by pushing the button on the dashboard (fig. 1 n° 24). There are four
radiator fan inversion relays (fig. 36).
-In addition, this sensor on the thermostatic valve sends a warning alarm and switches off the engine if its
temperature goes over 107°C.
-A micro-switch is located on the forward pedal detecting if the pedal is in the stop position, allowing therefore
the starting of the machine (fig. 35, ref. A).
-A sensor is placed on the parking brake locking pedal (fig. 35, ref. C) that detects when the parking brake is
engaged, allowing the engine to keep on running even if the operator has get off the machine.
-A micro-switch is placed on the rod of the reverse gear pedal that activates the reverse gear warning buzzer
(fig. 35, ref. B).
-The differential lock electric valve (fig. 37) is placed under the load chute: when it activates, a red led goes on.
-The full grass catcher micro-switch is mounted on a moving deflector inside the grass catcher and sends the
signal to disengage the blades when the grass catcher is full (fig. 38). It is important to adjust the position of the full
grass-catcher micro-switch according to the type of the grass to be cut, to ensure an even filling of the grass-catcher
(fig. 2B).
AIR FILTER
Check and clean the air filter (fig. 10) and the pre-filter every 8 hours. The air filter is e uipped with a depression
sensor that signals on the dashboard that the filter is clogged. For its replacement and the exact maintenance
intervals please follow the instructions and warnings in the engine manual. If working in a very dusty environment, it
is recommended to clean the air filter every 4 hours. Inside the air filter there is a safety cartridge to prevent
residues or impurities from getting inside the suction duct during the cleaning of the air filter. If the air filter looks
deteriorated or damage, it has to be replaced.
DIESEL FILTER
Replace the diesel filter cartridge (fig. 39) every 250 hours. For its replacement and the exact maintenance intervals
please follow the instructions and advices in the engine manual.
15

Translation of the original instructions
DIESEL DECANTING DEVICE
The decanting device (fig. 40) prevents li uid impurities in the diesel or water from depositing on the bottom and
therefore from getting in contact with engine parts. Clean the decanting device every 250 hours and wash the inside
with clean diesel too. Check the decanting device at every use. For the cleaning and the exact maintenance
intervals please follow the instructions and advice in the engine manual. Attention! When you fill up the diesel tank,
always use a very fine filter.
CLEANING
Clean the deck, the entry ducts and the grass catcher. Do not wash the engine compartment with water under
pressure, use compressed air or a vacuum cleaner.
TOW HITCH
The tow hitch is located at the rear of the mower. The max. towing weight is 200 kg on flat ground.
TOWING THE MACHINE WITH SWITCHED OFF ENGINE
Importamt: To tow the machine in case of engine failure unscrew by three turns the screw on the hydrostatic pump
(fig. 41) by using a 17 mm key; pay greater attention because doing so the efficiency of the self-braking device is
cancelled. Tow he machine a very low speed and only on small dis ances, maximum 100 me res, o avoid
seizing he hydraulic pump or engine.
STORAGE AND LACK OF USE FOR LONG PERIODS
Store the machine in a dry environment, sheltered from bad weather conditions and, if possible, covered up. Clean
the machine from grass and/or ground residues. If the machine is to be out of use for more than 30 days, detach the
red cable from the battery and follow the engine manual instructions. Remember to lubricate all the joints. Regularly
check that the battery voltage does not go under 12,5 Volts. If it is below, recharge the battery.
