INSTRU TIONS FOR USE
Before starting the engine, al ays check that:
the hydrostatic transmission cooling fins are clean (fig. 18).
the engine cooling grids are clean (fig.13, A).
the engine oil is at the correct level: scre the cap to check the level (fig.13, B)
the speed selection pedal is not depressed (fig.1, n.1);
the PTO s itch is OFF (fig.2 n. 3);
the air filter is clean (fig. 6, A).
to inspect the engine, lift the grass catcher and insert the red safety devices on the hydraulic

FD450/ Translation of the original instructions
STARTING WORK
Speed up the engine by pushing the throttle half- ay (fig. 3, n. 8), then engage the PTO s itch (fig.
2, n.3). Adjust the cutting height using the button (fig.2 n.4). The button (fig. 5, n. 11) is used to
raise the mo er deck. During ork the mo er deck must be set in the floating position (“FLOAT”).
AUTION: Do not engage the cutting blades ith the engine running at maximum r.p.m, engage
them only at half speed and outside the area to be cut.
FRONT HEADLIGHT
To s itch on the headlight, put the ignition key in the second position (fig. 4, no. 15). IMPORTANT:
Only use the headlight ith the engine running to avoid battery discharge.
IMPORTANT
1) Adjust the for ard speed in order to avoid overloading the deck hen at ork and al ayscut
ith the engine at maximum r.p.m..
2) Al ays keep the blades sharp. In case of ear sharpen or replace them as required.
Gently press the for ard pedal (fig.1, n.1) and start ork. Push the pedal to position A to travel
for ard and to position B to travel in reverse. If the pedal is released, the machine immediately
stops. Lever (fig.3, n.7) is the parking brake; in the “P” position (fig. 2) the parking brake is
engaged. When the grass-catcher is full the blades automatically disengage. The grass-catcher is
equipped ith an inner sensor that automatically disengages the blades hen the grass-catcher is
full (fig.38, A). The grass-catcher has therefore to be emptied. It can be emptied directly from the
driver's seat using the buttons (fig. 5, n.12 to raise the grass-catcher and n.13 to empty the grass-
catcher). The grass-catcher door opens automatically. The grid inside the grass-catcher must
al ays be kept clean to improve grass collection and to prevent clogging (fig. 7, B). During summer
and in very dusty environment it is recommended to fit the plastic protection plate (fig. 7A, A) inside
the grass-catcher. This plate and the necessary scre s are delivered ith the machine.
LOSING OF THE GRASS- AT HER
The grass-catcher can be checked opening the door (fig. 8, A). The closing can be regulated (fig.
8, B). The grass-catcher door opens automatically hen the operator uses the button from the
driver's seat. To keep the grass catcher door open use the rod (fig. 7, A). AUTION: Do not
engage the blades hen the grass catcher door is open.
TIPS FOR EFFI IENT USE
1. Check the ground condition before mo ing. Make sure there are no stones, sticks or other
foreign objects.
2. When mo ing, keep the engine at full revs and adjust the speed to suit the height of the
grass. Take care hen you come to thick clumps of tall grass; slo do n if necessary.
3. Sharpen the mo er blades frequently; the cut ill be better and the engine ill be under less
strain.
4. Engage the blades a fe metres outside the area to be cut.
5. Al ays keep the engine at full r.p.m. hen mo ing; if the engine revs drop, slo do n for a
moment to allo the engine to recover its r.p.m.
6. For the best la n appearance, alternate one longitudinal and one transverse cut, both at the
same height.
7. If the duct tends to become clogged ith grass, reduce the for ard speed as it may be too
high for the la n condition. If the problem persist, probable causes are blunt blades, dented
fins profile, slack belt or a clogged grass catcher grid.
8. If the grass is very long, it is best to cut in t o passes, the first ith the blades at the highest
level, perhaps orking on reduced idth, and the second at the final height required.
9. Take great care hen cutting close to bushes and lo kerbs hich might damage the edge of
the back and the blades.
10. Engage the parking brake once ork is finished (fig.3, n.7).
UTTING POSITION
To adjust the cutting height, use the button (fig. 2 n.4). On rough or uneven ground, al ays ork

ith the deck set at its highest cutting position in order to avoid damage to the blades. On the rear
part of the mo er deck three anti-scalp heels are fitted (fig. 26, A); their height can be adjusted
through the fixing holes.
BLADE ENGAGEMENT
The engagement or disengagement of the blades is effected by operating the s itch (fig. 2, no. 3).
When rotation is engaged the engine must be running at medium r.p.m and the machine must be
outside the area to be cut. Never start the blades ith the engine running at maximum rpm. The
machine is fitted ith an electromagnetic clutch hich also stops the blades during
disengagement. The blades should stop ithin 5 seconds from disengagement. Should this not be
the case, adjust the three nuts of the electromagnetic clutch placing a 0.3 mm feeler gauge under
the brake plate. N.B. This operation must be carried out by an authorised service center only.
Do not use the machine if the blades do not stop within 5 seconds after disengagement with
the engine at max. rpm.
OPERATOR ROLL OVER PROTE TION (ROPS)
Pay greater attention hen orking on slopes. IMPORTANT:
- Do not remove the ROPS from the machine
- Al ays keep the ROPS in perfect orking conditions, frequently check its fastening elements.
- Make sure the ROPS is not damaged during ork.
- Should the ROPS be damage, never repair it nor modify it. It must be replaced.
FOLDABLE ROPS
AUTION: To avoid injury or death from roll-over keep the roll-bar in the raised lock
position and use the seat belt.
Ensure that the seat is secured ith the seat latch. There is no roll-over protection hen the roll
bar is in the do n position. Please note:
- ROPS is a safety system

SEAT SUSPENSION AND SEAT TILTING ADJUSTMENT
Use the plastic knob (fig. 51, ref. F) to adjust the seat suspension, by turning it clock ise or
anticlock ise to make the suspension harder or softer. The seat is tilted pushing the lever behind
the seat (fig. 52, ref. G).
SLOPES
When orking on slopes and/or on uneven and et grounds that could cause the roll over of the
machine, it is absolutely necessary to use the machine ith the cutting deck lo ered to the ground
into orking position, roll-bar locked in the raised position and fastened seat belts. If possible
al ays travel up and do n rather than across slopes. When turning, take care that the heels on
the uphill side do not meet any obstacles (stones, logs, roots, etc.) hich might make you lose
control of the machine. If the drive heels tend to slip, slightly raise the mo er deck using the
hydraulic button or adjust the t o floating springs (fig. 10, A) to put more eight on the for ard
heels to gain more traction. Al ays assess the orking conditions and take care on damp ground
or et grass since the machine might slip. When going do nhill, start off slo ly and try not to drive
over dry or cut grass because the heels may lose grip. Never use this machine on slopes of more
than 12° (21%). If the heels tend to slip, use the differential lock (fig.1 n.2).
HOURMETER
The machine is fitted ith an hour meter ith three different functions:
1) It al ays sho s the no. of hours orked, even hen the key is not inserted.
2) It displays the no. of hours to the next engine oil change (OIL CHANGE IN...HS). The first oil
change must be carried out after the first 20 orking hours then every 100 orking hours. The
indicator “OIL CHANGE” flashes automatically hen it is necessary to change the oil.
3) It displays the no. of hours to the next lubrication (LUBE IN...HS). Lubrication must be carried
out every 40 orking hours. The indicator “LUBE” flashes automatically hen lubrication must be
carried out.
By pushing the hite button, you can choose the function to be displayed on the hour meter.
4) To reset the hour meter after an engine oil change or after lubrication proceed as follo s:
Push the button until the relative alarm flashes (OIL CHANGE IN...HS or LUBE IN...HS). Then
keep the button pushed for 6 seconds until the meter stops flashing.
SAFETY DEVI ES
The engine should stop henever:
- the operator leaves the seat hile the parking brake is disengaged and the PTO is engaged.
- the operator presses the for ard pedal hen the parking brake is engaged.
The engine ill not start if:
- the blades are engaged;
- the operator is not sitting in the driving seat and the parking brake is not engaged;

MAINTENAN E AND LUBRI ATION
AUTION!
- Disconnect the spark plugs before performing any cleaning, maintenance or repair
operation. Always wear suitable clothing and working gloves.
- When the machine or part of it is lifted to carry out maintenance operations, always
remember to use suitable fixing tools such as holders and safety locks.
- When carrying out maintenance operations and/or when the machine is tilted without
safety locks or supports, never leave it unguarded in places where inexperienced people
and children could have easy access to it.
- Protect the environment: carefully dispose of used oils, petrol and any other pollutant
product!
- Effective maintenance and correct lubrication help to keep the machine fully efficient.
ENGINE
For the lubrication intervals, follo the instructions outlined in the engine manual. For the INTEK
7220 professional series engine use SAE 30 oil (quantity 1,9 litres). Frequently check the engine
oil level (fig. 13, B). Replace both the engine oil and filter (fig. 13, C) as outlined in the maintenance
table. To unscre the oil drain plug (fig. 11, A) insert a rubber pipe then unscre the end part of
the plug and let the oil drain into a container; use a counter-key to hold the fixed component of the
plug. Remember to protect the belts, they must not come in contact ith the oil. The first
precaution is to ensure that the engine is correctly serviced with the air filter, cooling fins
and cylinder head clean and the oil at the correct level. Check the air filter every 4 hours or
even more often in very dusty environments (fig. 6, A). Check that the engine cooling intake grid is
al ays clean (fig. 13, A).
HYDROSTATI AXLE
Visually check the oil level in the expansion tank (fig. 16, B). When the engine is cold the oil level
must be 1 cm above the bottom of the expansion tank. Frequently clean the hydraulic motor
cooling fins and the fan especially in summer and every 4 hours in very dusty environments
(fig.17). Replace the oil after the first 50 hours, and then every 200 hours. Exclusively use SAE
20W50oil, 2,5 litres. To replace the oil follo the instructions belo :
1. Unscre both drain plugs (fig. 15, A – B)
2. Remove the left cover to gain access to the oil refilling cap placed on the tank (fig. 16, A).
3. Unscre the oil filter of the hydrostatic transmission and clean it. Replace if necessary (fig. 12,
A).
4. Inside the tank there is a hydraulic filter (fig. 14, B). This filter does not require any special
maintenance.
5. Once the oil has been totally drained, tighten both plugs again (fig. 15, A – B).
6. Activate the by-pass lever (fig. 27, A) by pushing the lever to ards the machine to let the oil
drain from the main hydrostatic circuit.
7. Remove the connection on the hydrostatic transmission (fig. 19, B) and fill the hydrostatic
chamber ith oil (fig. 18 – HYDRO CHAMBER).
8. Remove the cap on the hydrostatic transmission (fig. 19, A) and fill the gear chamber ith oil
(fig. 18 – GEAR CHAMBER).
9. Scre the cap and remount the expansion pipe (fig. 19, C) and make sure the oil level is 1 cm
above the bottom of the expansion tank (fig. 16, B).
10. Purge the hydrostatic transmission follo ing the instructions belo :
a) put the machine in a steady, safe position ith the front heels raised from the ground,
make sure the by-pass valve is activated, s itch the engine on, ait a fe minutes then repeatedly
engage the for ard and the reverse gear by pressing the pedal (fig. 1, n. 1).
b) deactivate the by-pass valve (fig. 27, A) by pulling it and repeatedly engage the for ard
and reverse gear by pressing the pedal (fig. 1, n. 1).
c) Put the machine on the ground again and check if the machine moves for ard and stops
correctly: in case of poor performance, loss of traction or noises coming from the hydrostatic axle,
repeat the purge (see point no. 10I.
11. Visually check the oil level in the expansion tank (fig. 16, B). When the engine is cold the oil
level must be 1 cm above the bottom of the expansion tank.
12

FD450/ Translation of the original instructions
IMPORTANT: this operation has to be carried out in a clean environment to prevent
impurities or ground residues from entering the hydrostatic axle and causing damage.
Therefore, we recommend the replacement of oil into the hydrostatic axle to be carried out
only by a Grillo authorised service centre.
HYDRAULI IR UIT
Frequently check the hydraulic oil level in the tank hen the engine is cold and the grass-catcher is
closed. Use OSO 46 hydraulic oil, total amount of 3,5 litres.
IMPORTANT: Replace the hydraulic oil after the first 500 orking hours then every 1000 hours. To
drain the oil use the appropriate drain plug (fig. 14, C).
Replace the oil before 500 orking hours only if:
- the oil is black
- the oil has a hitish colour (it has been contaminated ith ater);
- there are black residues (partial oil deterioration).
REAR WHEEL AXLE
Grease the rear heel pivot pins every 20 hours (fig. 41, A).
DIFFERENTIAL LO K
To engage the differential lock, press the pedal (fig. 1, n.2). Adjust the control cable and lever so
that the differential lock can be correctly engaged and disengaged (fig. 9). When releasing the
pedal, the differential lock must disengage. Do not use the differential lock hen changing direction
because the differential lock components could be strained.
SHARPENING THE BLADES
A blunt blade pulls at the grass, giving it an unsightly appearance. The cutting edges of both
blades must therefore al ays be kept sharp and orn blades must be replaced. To sharpen the
blades first remove the mo er deck (fig. 26) then follo the instructions belo :
1) Position the mower deck in its lowest cutting position.
2) Remove the protection guard above the deck by unscre ing both ing nuts (fig. 25).
3) Remove the pin (fig. 25, A).
4) Turn the lever anti-clock ise (fig. 25, B).
5) Remove the PTO belt (fig. 25, C).
6) Detach the ire of the electric ire (fig. 25, F).
7) Release the fork (fig. 31, B), pull the deck for ard and set it vertical (fig. 26). It is recommended
to open the grass catcher and take off the discharge chute. (fig. 32, A).
Worn blades lose their cutting efficiency and tend to become unbalanced, causing the mo er to
vibrate. If the unbalance persists even after sharpening, check the balance by inserting a
scre driver in the hole in the centre of the blade and hold up, grind the blade until it remains
horizontal and is therefore balanced. To remove a blade, take hold of it firmly, earing safety
gloves, and undo the centre bolt (IMPORTANT: the right hand blade bolt has a left thread).
AUTION!
Al ays replace damaged or orn-out blades; never attempt to repair them! ALWAYS USE
ORIGINAL BLADES!
AUTION!
In order to reassemble the cutting deck, you have to fit together the cutting deck lead (fig.23, A)
ith the one hich is located on the machine, bet een the heels, in the centre.
LUBRI ATION WITH GREASE
Follo the lubrications points scheme (fig. 41A – 41B). Lubricate ith grease every 40 hours the
rear axle joints, pedals and the grass-catcher lifting arms.

UTTING DE K ADJUSTMENT
A level deck is essential for a uniform cut. With the mo er on a flat surface, check that the tyre
pressures are correct and check the float spring tension (fig. 10, A). If a satisfactory parallel set-up
cannot be achieved, adjust the register (fig. 20, A). To adjust the mo ing height, place t o 25 mm
shims at the sides under the edge of the deck and put the deck in its lo est position using the
button on the dashboard. Use the scre (fig. 24, B). Before carrying out this procedure loosen the
t o scre s (fig. 24, A). at the rear part of the mo er deck, t o anti-scalp heels are fitted (fig. 34,
C). Their height can be adjusted through the three fixing holes.

belo :
1) Remove the protection guard above the deck by unscre ing the t o scre s (fig. 25).
2) Remove the pin (fig. 25, A)
3) Turn the lever anti-clock ise (fig.25, B)
4) Remove the PTO belt (fig. 25, C)
5) When refitting the belt, make sure the belt guide is located inside the t o sides of the belt (fig.
37, A).
The PTO belt does not need to be regulated because it is self-adjusting.
UTTING DE K BELT
This belt is a double A section and allo s the blades to counter-rotate. The belt tension is self-
adjusting thanks to the spring (fig. 34, A). The spring must have 130 mm length (coils length). To
replace the cutting deck belt follo the instructions belo :

OLLISION WITH A STONE OR OTHER OBSTA LE
– Stop the machine.
– S itch off the engine, remove the mo er deck, raise it and check that the blades have not been
damaged. Replace them if necessary (fig. 26).
IMPORTANT
To move the machine ith the engine off, activate the by-pass valve using the lever (fig. 27, A).
ME HANI AL PARKING BRAKE
Al ays keep the cable (fig. 28B, A) properly adjusted, so that the parking brake is engaged setting
the lever (fig. 3, n. 7) into the parking position (symbol “P”). The parking brake is disengaged by
setting the lever again. When the parking brake is engaged and the PTO is disengaged, it is
possible to temporarily leave the driving seat hilst the engine keeps on running. Caution: never
leave the machine unattended hile engine is running.
ADJUSTMENT OF THE NEUTRAL/IDLE POSITION
Gently press the for ard pedal (fig. 1, n. 1): pressing the pedal in the A position the machine
moves for ard, pressing the pedal in the B position the machine moves back ards. When
releasing the pedal the machine stops. If the machine does not stop completely hen releasing the
pedal, the neutral position can be adjusted through the adjuster (fig. 46). This adjustment has to be
carried out ith the engine running, the machine in a steady, safe position and the front heels
raised from the ground. Remove the cover of the steering column, then loosen both scre s (fig. 46,
A) and adjust the lock bracket of the for ard spring (fig. 46, B) so that the heels stop completely.
Once the adjustment is completed, tighten both scre s again (this procedure has to be carried
out by an authorised Grillo service centre only).
IMPORTANT: this adjustment has to be carried out gradually, performing slight adjustment at a
time. By increasing the stroke of the lever on the hydrostatic transmission through the rod
connected to the pedal, the heels have more traction and go faster (this procedure has to be
carried out by an authorised Grillo service centre only).
GRASS- AT HER
The hydraulic cylinders for lifting and tipping of the grass-catcher can be adjusted. Pay attention
not to force the cylinders against the stroke buffers. The parallelogram rod is provided ith left and
right-hand threads. These can be adjusted to make the grass-catcher perfectly fit the discharge
chute (fig.40, B). The t o brackets that fix the discharge chute can be adjusted too (fig. 32, B). This
operation must be carried out hen the grass-catcher is closed. The tipping hydraulic cylinder can
be adjusted so that the grass-catcher leans against the front stroke buffers. Pay attention not to
force the cylinders against the stroke buffers: the cylinder must just touch the buffers.
REAR AXLE
Lubricate ith grease all the joints. Should signs of an abnormal ear of the heels appear, use a
leveller bar to align the rear heels ith the front heels. Use the nut (fig. 33, C).
ELE TRO-HYDRAULI DISTRIBUTOR
The electro-hydraulic distributor (fig. 13, E) is made up of 3 components held together thanks to
four rods and nuts hose tightening torque is 5 Nm. If this value is not respected, the electro-
hydraulic distributor does not ork.
ELE TRI S
The electrical system is protected by t o fuses. The 16A fuse (fig. 2, n. 6) is located on the
dashboard and protect all the functions of the machine: if tripped, the engine only can be started.
The other 25A fuse is located near to the electro-hydraulic distributor and protects the hole
electric iring. If tripped, this fuse stops all the electric functions of the machine (fig. 29, A). After
identifying and repairing the fault, replace the blown fuse with another of the same rating.
Never replace a fuse with one of different rating. If the problems persist after the above
procedures have been carried out, contact an authorised service centre. Never attempt to carry out
complex repairs if you do not have the necessary equipment and technical skills. If the engine or
the battery are out of order, the grass-catcher can be opened manually: insert the key and sit on
17

FD450/ Translation of the original instructions
the driver's seat. In this ay the hydraulic valve is relieved. Push the button to open the grass-
catcher (fig, 5, n. 13) and open the grass-catcher manually. The battery is located under the grass-
catcher in the rear part of the machine (fig. 33, A). If it is out of order, the battery can be removed
and recharged.
FUN TIONS OF THE MAIN ELE TRI AL OMPONENTS
- A safety sensor detects if the grass-catcher is in its orking position (fig. 13, F). Other ise the
blades ill not engage.
- On the for ard pedal there is a micro-s itch that allo s to start the machine only if the pedal is in
neutral/idle position (fig. 30).
- A micro-s itch is located on the parking brake (fig. 28A, A) that detects hen the brake is
engaged and allo s the engine to stay on even if the operator is not seated. This micro-s itch also
s itches off the engine if the for ard pedal is pressed hen the parking brake is engaged.
- On the electromagnetic clutch (fig. 12, B) there is a diode preventing back current.
- A sensor is located in the grass-catcher disengaging the blades hen the grass-catcher is full
(fig. 38, A).
- Inside the steering column there are an electronic control unit (fig. 36) that controls all the electric
functions of the machine (e.g. PTO, safety micro-s itches...) and a relays that controls the electric
buttons (fig. 35, A).
FINISHING WORK
When you finish mo ing, disengage the blades. To stop the machine, release the for ard pedal
(fig. 1 n. 1), set the throttle lever to the minimum and turn off the engine by turning the key into
STOP position (fig. 4, n. 15). Engage the parking brake (fig. 3, n. 7) by pulling the lever into the “P”
parking position.
LEANING
Internal cutting deck ashing: this operation must be done on a solid floor. You have to connect a
ater pipe to the proper joint (fig.31, A) and let the ater flo for a fe minutes:
-the driver must be seated in the driver's seat.
-the engine must be running;
-the gearbox must be in neutral gear;
-the blades must be engaged.
During this procedure, the cutting deck must be set in its lo est position.
Never use a high-pressure po er jet to ash out the engine compartment: use compressed air or
a vacuum cleaner only.
DIS HARGE HUTE
To remove the chute (fig. 32, A) first open the grass-catcher, lift both red safety locks (fig. 32, C)
and remove the chute by pulling it to the top.
