wheels upstream do not strike obstacles (stones, branches, roots, etc.) which might cause the machine
to overturn, or lead to loss of control. Assess the conditions and take care if the round and rass
are damp since the machine mi ht slip. Downhill, set off at low speed and do not pass over dry or cut
grass since the wheels lose grip;
INTERVENTION OF SAFETY DEVICES
Remember that the engine will stop whenever:
– The operator gets up from the seat.
The engine will not start up if:
– The blade is engaged.
– Nobody is sitting in the driver’s seat.
– If the cutting deck isn’t at the highest setting.
USEFUL RULES FOR EFFICIENT USE
1) Never strain the engine: when fumes are emitted from the exhaust it means that it is being strained.
Slow down.
2) Do not leave the machine out in the rain.
3) requently sharpen the mower blades: the cut will be better and the engine will not be strained as
much.
4) Check the land before mowing to make sure that there are no stones, sticks or foreign bodies.
5) Keep the engine at peak r.p.m. during mowing, adjust the speed according to the height of the grass.
6) Keep the rilles above the en ine and the coolin fins of the hydraulic motor (fi . 5 – 7) clean.

MAINTENANCE AND LUBRICATION
CAUTION!
- Disconnect the plu s before performin any cleanin , maintenance or repair operation. Always
wear suitable clothin and workin loves.
- When the machine or part of it is lifted to carry out maintenance operations, always remember
to use suitable fixin tools such as holders and safety locks.
- When carryin out maintenance operations and/or when the machine is tilted without safety
locks or supports, never leave it un uarded 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!
- Efficient maintenance and correct lubrication help to keep the machine in perfect workin
order.
ENGINE
or the lubrication intervals, follow the instructions provided in the engine handbook; the oil must in any
case be chan ed after the first 20 workin hours, using AGIP SAE 30 engine oil. To remove the oil,
cut the plastic strapping that keeps the oil discharge pipe attached to the frame (fig. 20B) and position a
container to collect the exhaust oil. Then unscrew the tap at the end of the pipe using a lock key. Change
the oil filter (fig. 10).
FINAL DRIVE GEARBOX
Check the oil level every 100 hours by unscrewing the cap (fig. 11, ref. A); if necessary top up with
80W90 (API GL-5) gearbox oil. To drain the oil unscrew the cap (fig. 11, ref. B). Change the oil every
1000 hours. Quantity 1.9 litres (fill through the tap fig. 11A).
HYDRAULIC MOTOR
Check the level in the expansion tank when the motor is cold. It should come up to the level notch (fig.
3). If necessary, add AGIP SAE 15W50 or 20W50m oil. Change the oil every 200 working hours. To drain
the oil, unscrew the cap (fig. 4); pour into the tank. Keep the fins and coil of the hydraulic motor (fig. 3A
and 7) thoroughly cleaned. Quantity 1 litre.
AIR FILTER
Check the air filter every 4 hours, or more frequently if working in a very dusty environment (fig. 6).
Check the air intake grid for engine cooling (fig. 5). The external and internal grids must always be kept
clean to avoid blocking the air flow needed for the engine cooling. Keep the engine compartment, the
hydrostatic transmission and the intake grid clean.
CHECKING THE BLADES AND DECK
A blunt blade tears the grass, leaving it unattractive. The blades cutting edges must be always
sharpened. To remove a blade, take hold of it firmly, wearing work gloves, and unscrew the central
screw, remembering that the screw is located on the right. Sharpen both cutting edges using a medium-
grain grinding wheel and check that the blade is balanced by standing it on a round bar inserted in the
central hole.
CAUTION!
Tighten the fixing screw firmly. Always replace damaged or crooked blades; never attempt to repair them!
ALWAYS USE ORIGINAL BLADES!
110 MP CUTTING DECK
This cutting deck with 3 blades has a cutting width of 1100 mm. It has two functions: rear discharge and
mulching. If you want to change from rear discharge function to mulching function you simply have to
use the lever. It is namely not necessary to change the blades (fig. 26 – 27). The cutting height can be
adjusted electrically using the button on the dashboard (fig. 36).

MD22/ Translation of the original instructions
MAINTAINANCE 110MP CUTTING DECK
To ensure the deck belt works properly and to have a uniform cut, please follow these instructions:
– put the cutting deck in its lowest position.
– adjust the front arms fig. 34 in order to set the front part of the cutting deck at 35 mm from the ground
(fig. 28): you have to measure the point A as indicated (fig. 29).
– regulate the adjusting device (fig. 35) in order to set the rear part of the cutting deck at 35 mm from the
ground (fig. 30): you have to measure the point B as indicated (fig. 29).
To check the cutting deck belt you have to unscrew the knob D in fig. 31 and remove the two protections.
If you see that the length of the belt has changed, resulting in malfunctioning, you can regulate the belt
tension using the adjusting screw (fig. 32). If you want to replace the belt, please follow the fig. 33 to re-
assemble it. The spring has to be adjusted at 86 mm and it is indicated by the red arrow (fig. 32B). The
stretcher has to be lubricated every 50 working hours (fig. 32/C).
ENGINE BELT – CUTTING DECK BLADE
The engine – blade belt is self-adjusting. Therefore no adjustment is required. Simply check the spring
tension (fig. 15). Check that during operation the belt I always in the centre of the stretcher (fig. 15, ref.
A). The stretcher has to stick about 5/8 mm out of the frame (fig. 24). To replace the belt remove the
spring (fig. 15, ref. B)
ENGINE – HYDROSTATIC TRANSMISSION BELT
Whenever there is a change in belt length (causing therefore its malfunctioning), the tension can be
regulated by means of the adjustment device (fig. 16). Take care not to compress the spring beneath the
unit completely; belts must be neither too tight nor slack. The spring must be kept set at 44 mm (fig. 16).
BLADE ROTATION
Rotation is started and stopped using the switch (fig. 1, no. 1). When rotation is engaged , the engine
must be running at medium r.p.m (see throttle sticker) and the machine must not be in the grass for
cutting. Never start the blades with the engine at maximum rpm. The machine is equipped with an
electromagnetic clutch which also brakes the blade during disengagement. The blades are also
disengaged automatically when the cutting height adjuster lever is moved to the highest position.
CHANGING THE BELTS
The movement is transmitted from the motor to the hydraulic transmission and to the blades by means of
v-belts. Replace the belts as soon as they show si ns of wear! Their replacement and subsequent
adjustment are fairly complex procedures and must be carried out by an Authorised After-Sales Service
Centre. or the two transmission and hydraulic engine belts proceeds as follows:
-remove the rear and top grids
-undo the belt stretcher nut (fig. 15)
ALWAYS USE ORIGINAL BELTS!
TRACTION RELEASE LEVER
The traction release device is located behind the seat; if the machine breaks down, to allow it to be
towed or moved by hand, move the lever outward (fig. 20A). In the position (fig. 20B) the machine is in
working condition. Check that during working the hydraulic engine piston does not remain pressed down;
if necessary, adjust the nut (fig. 21).
DIFFERENTIAL LOCK ADJUSTMENT
The differential lock has to be activated when the pedal is half way of its travel (fig. 8). To adjust the
activation point of the differential lock use the screw (fig. 9).

MD22/ Translation of the original instructions
TO QUIT WORKING
After mowing, disengage the blades and drive back to base with the cutting deck in the highest position.
To stop, move the travel lever to the STOP position (fig. 1B, no. 2), set the throttle lever on the minimum
r.p.m., switch off the engine by turning the key in the STOP position (fig. 1, no.7) and lower the deck to
the lowest position. Engage the parking brake (fig. 23).
CLEANING
Clean the outside of the mower after each use.
STORAGE AND PROLONGED PERIODS OF DISUSE
Store the mower in a dry place, away from atmospheric agents, and preferably cover with a sheet. If the
mower is not going to be used for a long period (over 1 month), disconnect the red battery cable and
follow the instructions given in the engine manual. Also lubricate all of the articulated joints. Regularly
check that the battery voltage does not drop below 12 volts. If it does, recharge the battery.
If the machine is to be out of use for more than 30 days (models with petrol engine), drain the fuel from
the engine to prevent sticky deposits from forming in the fuel intake system or in vital parts of carburettor.
To avoid this procedure, it is possible to save fuel in storage up to 12 months by using an appropriate
fuel stabilizer. Add the such additive to the fuel in the tank or in the fuel container. Run the engine for a
while to let the stabilizer get into the fuel system. Caution: if the engine is fed with petrol containing
alcohol, drain the fuel tank and run the engine until there is no fuel left.
TRANSPORTING THE MACHINE
If the machine has to be transported on a lorry or a trailer, fasten it to the vehicle using ropes or cables.
