GGP Italy SPA Lawn Tractor 71503777 2 Operators Manual

							with the clutch out! Always engage a low gear before leaving the
machine stopped and unattended.
For hydrostatic drive models:
Go down slopes without touching the pedal (☛4.32) to take advantage of the
braking effect of the hydrostatic drive when the transmission is not engaged.
5.6 TRANSPORTING
If the machine is transported on a truck or trailer, use
suitable equipment for lifting and an appropriate number of people for
the weight involved and the type of lifting system used. The machine
must never be lifted by rope and tackle. While being transported, close
the fuel stopcock  (  if fitted), lower the cutting deck, engage the park-
ing brake and fasten the machine securely with ropes or chains to the
hauling device.
5.7 ADVICE ON HOW TO OBTAIN A GOOD CUT
1. To keep a lawn green and soft with a good appearance it should be cut regu-
larly without damaging the grass.
2. It is always better to cut the grass when dry.
3.The blades must be in good condition and well sharpened so that the grass is
cut straight without any ragged edge that leads to yellowing at the ends.
4.The engine must run at full speed, both to ensure a sharp cut of the grass
and to get the necessary thrust to push the cuttings towards the exit.
5.The frequency of mowing should be in relation to the rate of growth of the
grass, which should not be left to grow too much between one cut and the next.
6.During hot and dry periods, the grass should be cut a little higher to prevent
the ground from drying out.

							EN 31 HOW TO USE THE MACHINE
7.If the grass is very tall, it should be
cut twice in a twenty-four hour period.
The first time with the blades at maxi-
mum height, possibly reducing the cut-
ting width, and the second cut at the
height wanted. 
8.The appearance of the lawn will
improve if you alternate the cutting in
both directions.
9.If the engine speed is lowered while
you are cutting grass or if the cutting deck tends to get blocked, you should
reduce the forward speed since this may be too high for the condition of the
grass. If the problem persists, the probable causes are either badly sharpened
blades or deformed wings.
10.Be very careful when mowing near bushes or kerbs since these could distort
the horizontal position of the cutting deck, and damage its edge as well as the
blades.12

6.1 SAFETY RECOMMENDATIONS
Before cleaning, maintenance or repair work, take out
the ignition key and read the relevant instructions. Wear suitable clothing
and strong gloves when dismantling and refitting the blades and in all
other hazardous situations for hands.
Never use the machine with worn or damaged parts.
Faulty or worn-out parts must always be replaced and not repaired. Only
use genuine spare parts: those that are not of an equivalent quality may
damage the machine or endanger the safety of yourself and others.
Never get rid of used oil, fuel or other pollutants in unautho-
rised places!
6.1.1 L
IFTING THE FRONT
If you need to have easy access to the lower part of the machine, it is possible to
lift the front part of the machine.  
Place the machine on firm and flat ground. At least two
competent people should be involved in this operation to assure neces-
sary safety.
Position a support block (1) in wood (other other material) that can bear the
weight of the machine; it should be 30-35 cm high with a base of at least 100 x
25 cm. 
To stop the machine from accidentally
moving backwards:
– engage the parking brake;
– shift the gear lever to 1st gear (  
in the mechanical transmission
models)  or (  in the hydrostatic
models)check that the transmis-
sion release lever ( ☛ 4.33) is in
position «A» (engaged).

– position a wedge (2) behind each of the two rear wheels.
– raise the back of the machine, holding the parts with a secure grip. Then push
the support block (1) under the rear wheels and lower the machine until the
wheels rest on the block.
Check that the machine is stable before doing any work
and avoid carrying out any operations that can cause it to fall.

This is a sealed single unit that does not require maintenance. It is permanently
lubricated and this lubricant does not need changing or topping up.
6.2.5 B
ATTERY
To ensure long life to the battery it is essential to keep it carefully maintained.
The machine battery must always be charged:
– before using the machine for the first time after purchase;
– before leaving the machine for a prolonged period of disuse;
– before starting up the machine after a prolonged period of disuse.
– Carefully read and observe the recharging procedure described in the booklet
provided with the battery. Failure in following the procedure or in charging the
battery could permanently damage the battery elements.
– A flat battery mustbe recharged as
soon as possible.
Recharging must be
done using a battery charger at constant
voltage. Other recharging systems can
irreversibly damage the battery.
The machine comes with a connector (1)
for recharging, to be connected to the cor-

responding connector of the special “CB01” maintenance battery-charger sup-
plied ( if included)or available on request  (☛8.5).
This connector must only be used for connection to the
“CB01” maintenance battery-charger. For its use:
– follow the instructions given in the relative user manual,
– follow the instructions given in the battery booklet.
6.3 CHECKS AND ADJUSTMENTS
Summary of the main situations where work may be required
6.3.1 D
ISMANTLING, SHARPENING AND BALANCING BLADES
Check that the blade is sharpened properly and firmly fixed to the bracket.
– A badly sharpened blade pulls at the grass and causes the lawn to turn yellow.
– A loose blade causes unusual vibrations and can be dangerous.
All operations on the blades (dismantling, sharpening,
balancing, remounting and/or replacing) require a certain familiarity and
special tools. For safety reasons, go to a specialized centre if you do not
have the right tools or experience.
Wear strong gloves when handling the blades.
To remove a blade, hold it firmly and undo the central bolt (1) in the direction

Sharpen the two cutting edges using a medium grade grinding wheel and check
the balance by holding the blade up with a round 18 mm Ø bar inserted in the
central hole.
Damaged or bent blades must always be replaced;
never try to repair them! ALWAYS USE MANUFACTURERS GENUINE
REPLACEMENT BLADES
BEARING THE SYMBOL   !
When
assembling the blade, always
follow the instructions given,
making sure the blade wings
are facing towards the inside of the
cutting deck and the cupped side of
the elastic disc (1) is pressing against
the blade. Tighten the fixing screws
(2) using a torque wrench set to 45-
50 Nm. If one or both shaft hubs (3)
come off when dismantling the blades, make sure the keys (4) are secure-
ly lodged in place.
6.3.2 C
UTTING DECK ALIGNMENT
The cutting deck should be properly set to obtain a good cut 
For achieving good results from cutting, the front part
should always be 5 - 6 mm lower than the rear.

– Put the machine onto a flat surface and
check the tyre pressures;
– put 26 mm blocks (1) under the front
edge of the deck and 32 mm blocks (2)
under the rear edge, and then put the
lifting lever into position  «1»;
– fully loosen the adjuster (3), the nuts (4 –
6 – 8) and the locknuts (5 – 7 – 9) of the
three trace rods until the deck is resting
on the blocks;
– screw the two upper right nuts (6 – 8)
and the lower left nut (4) until the deck
starts rising; tighten the three locknuts (5
– 7 – 9) and turn the adjuster (3) until the
control cable is taut.
Any difference in height from the ground
between the right and left side of the deck
can be compensated by turning the two
nuts (4 – 8) and locknuts (5 – 9) of just the
back rods.
Move the control lever to 2 or 3 different
positions, making sure that the deck rises
evenly and that the difference in height
from the ground remains the same
between the front and rear edge.
If the front part rises too early or too late, you can regulate the movement by
turning the nuts (10) on the connecting rod (11).
Screwing the nuts on the rod makes the rear part rise earlier, while unscrewing
them does the opposite.
Always remember to fully tighten all the nuts and locknuts when the adjustment
has been made.
If you are unable to get the cutting deck adjusted properly, consult a Licensed
Service Centre.
