15) CAUTION! Do not transfer the machine with lifted cutting deck. Use the cutting deck hydraulic lifter only to get
over obstacles, mount on pavements or on kerbs. It is compulsory, instead, to travel on public streets with a
type-approved machine, endowed with a lights system, a plate and with the cutting deck up.
MOWING POSITIONS
Use the pins (fig. 1 n° 12 and fig. 12) to adjust the cutting height. When working on rough terrain, with bumps or
humps, it is best to use the deck in the highest cutting position to avoid impact with the blade. Attention! During the
cut the deck lifting button has to be in the «floating» position.
CUTTING DECK
Mulching system (lever straight up fig. 25). This system is designed to cut and chop grass 10/15 cm high. This
operation is best carried out with dry grass as the turbulence inside the deck mulches it better. It is advisable not to
stop the machine after cutting but to continue over the mown lawn for a few minutes to discharge the grass from the
inside of the deck. Inspect the blades regularly and sharpen or replace them if necessary. In some areas of Europe,
2 passes are made when using the mulching method; 1/3 of the grass height is cut in the first pass and the other 2/3
in the second. Please assess which method best suits your needs and your type of grass. Should the grass be taller
than 15 cm, please use the cutting deck in the rear discharge function (fig. 23).
SLOPING GROUND
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, 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 locking (fig. 1 n° 26) must be used only in special cases, for example: if during a strong descent you
want to reverse the direction of travel, to avoid the rear wheels skidding, or in case of load on motor vehicle in
reverse motion with the presence of ramps. Normally do not engage the differential locking.
Do not run any risks, 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. 18° or 32%).
SAFETY DEVICE TRIGGERING
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 feed pedals and the reverse pedal are not in the stop position;
-
Attention! When the parking brake is engaged, it is possible to leave the driving seat with the engine on, if the
blades are disengaged.
CAUTION!
Stop the engine and remove the ignition key before carrying out any cleaning, maintenance or repairs.
Always wear suitable working clothes and safety gloves.
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 mower perfectly working.
ENGINE
For the lubrication intervals follow the directions given in the engine manual; it is in any case indispensable to
change the oil and the filter after the first 50 working hours and then every 250 hours. For the diesel engine
use SAE 15 W 40 oil, 5 litres. When you change the engine oil, it is necessary to change also the oil filter (fig. 14,
ref. B). To remove the engine oil, unscrew the lid on the right side of the oil cup. Pour in the oil trough the lid (fig.
33). 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. 9) and the prefilter (fig. 13) every 8 hours or even more frequently in dusty
conditions. 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.
