							5.3 REMOVAL OF THE WHEELS COVER
Removing the wheels cover may be necessary for:
–improving access around the engine,
–removing the rear plate.
Unscrew the lever knob (2).
Take out the split pin 
(3)and remove the pin (4)to
dismantle the seat.
Release the spring 
(5)of the fixed cover of the
grass-catcher 
(6), by undoing the screws (7)which
hold on the small plate 
(8).
Undo the two self-threading screws 
(9)and loosen
the two screws 
(10)with nuts that hold the cover
onto the rear plate.

Lift the wheels cover [see 2.5].
Undo the six screws which attach the tubular ele-
ment. Two of them are short 
(11)and four are longer
(12)and they can be reached from below.
When reassembling, do not forget to reattach the
connector 
(3)of the seat microswitch and to make
sure it works.

Close up the wheels cover  [see 2.5].

							5.4 REMOVAL OF THE REAR PLATE
The rear plate does not need to be removed for
access to other parts for work. The following pro-
cedure is only for replacing with a new one.

Remove the wheels cover [see 5.3].
Close up the frame of the cover, tightening the fix-
ing nut 
(1).
Detach the electrical connections from the “grass-
catcher attached” microswitch 
(2)and the “grass-
catcher full” microswitch
(3)and release the stop
cable
(4).
The plate is hinged at the base of the machine’s
frame by two small plates 
(5), each of which is fixed
by four screws 
(6), and is attached to the frame of
the wheels cover by four screws 
(7).
First of all, undo the four upper screws 
(7)and then
dismantle the two lower plates 
(5), ensuring that the
wheels cover frame has the necessary stability
since, by removing the plate, it is without support at
the back.

5.5 REMOVAL OF THE COLLECTOR CHANNEL
Removing the channel is necessary for:
–draining oil from the engine,
–accessing the right-hand side of the engine.

Turn back the wheels cover [see 2.5].
The channel 
(1)can be removed by releasing one of
the two split pins
(2)and taking out the pin (3).

							5.6 REMOVAL OF THE ENGINE
Since there are different types of drive, the stages
described here refer to those shared or similar in
all types of engine.

Turn back the wheels cover [see 2.5].
Disengage the blade to loosen the belt. The trans-
mission belt should also be loosened.
This is done by ...
➤In mechanical drive models:engaging the
parking brake. 
➤In hydrostatic drive models:releasing the
spring 
(1)of the stretcher.
Undo the central screw 
(2)and take out the pulley
(3) from the shaft.
If it is difficult to take out, use the special extractor #
code 60253000/0 inserted into the holes 
(4)of the
pulley, but do not completely undo the screw 
(2)so
that the extractor puts pressure on the head of the
screw and does not damage the threaded hole of
the shaft.
Remove the protection from the exhaust 
(5)(differ-
ing according to the types of engine), and discon-
nect the accelerator cable control and all the electri-
cal wires.
Close the fuel cock and detach the fuel pipe, 
taking
care not to spill fuel
.
Find and undo all the screws holding the engine to
the frame, grip the engine firmly and lift it, taking the
necessary care bearing in mind that its weight is
around 25 - 35 kg.
NOTE
Some types of engine are held with screws of differ-
ent lengths and in different positions, so it is best to
label them so that no errors are made when
reassembling.

							When reassembling, fully tighten the screws for the engine and the pulley to the amounts shown.
Remember to fit the clamp back on the fuel pipe and 
check that it does not leak. 
Reattach all the electrical and earth contacts and refit the protection covers 
(5).
➤For hydrostatic drive models:refit the spring (1) of the stretcher.
Reattach the accelerator cable and ... 

Adjust the «MINIMUM» position [see 6.7].

Close up the wheels cover [ see 2.5].

							5.7 REMOVAL OF THE REAR AXLE
The rear axle (Transaxle) is made up of single
maintenance-free sealed unit which includes the
transmission unit ( 
➤ mechanical or  ➤ hydrostat-
ic) and the differential. 
It only needs to be removed to be replaced or for
an overhaul by the Manufacturer’s Service Centre.

Lift the wheels cover [see 2.5].

Dismantle the engine pulley [see 5.6] to release
the belt.
Put two blocks 
(1)of around 150 mm under the two
ends of the rear plate and then take off the rear
wheels.
➤In mechanical drive models:
Engage the parking brake to slacken off the
transmission belt and remove the pin 
(2)from the
brake rod 
(3).
Disconnect the control rod
(4)of the gear-change
by taking out the split pin 
(5), and disconnect the
wires of the microswitch
(6)for signalling the
“neutral” position.
Also dismantle the pulley 
(7)held by a snap ring
(8).
The unit is supported by two brackets 
(9)–
depending on the type used – with their screws
(10)and (11)and is fastened to the frame (12)by
four screws 
(13).
Loosen the screws
(11)to permit a minimum of
movement of the brackets
(9)and undo the
screws
(10). Then carefully undo the four lower
screws 
(13), giving sufficient support to the unit so
that it does not fall, bearing in mind its weight of
around 15 - 22 kg.
Reassemble in the reverse order, being particularly
careful with the two self-tapping screws 
(10)
which, if not screwed in correctly, can damage the
internal thread preventing correct fastening.
NOTE
When tightening the screw(11)on the left-hand
side, be careful with the stop cable 
(14), which
must always be taut and straight when the cover is
open.

							➤In hydrostatic drive models:
Disconnect the drive control rod (21)by removing
the split pin 
(22), remove the pin (23)from the
brake rod 
(24)unscrewing nut (25); move the ten-
sioner guide pulley 
(26)to the right and free the
pulley 
(27)from the belt (28).
Disconnect the transmission release control rod
(29), held by a bevel fastener (30).
The group is supported by a support 
(31)fixed by
a screw with nut 
(32)and is fixed to the chassis
by four screws with relative nuts 
(33).
Unscrew nut 
(32), then carefully unscrew the nuts
(33)of the four lower screws, suitably supporting
the group so it cannot fall and taking account of
the weight of approximately 20 - 22 kg.
Carry out the above operations in reverse to
reassemble. 
NOTE
When the transmission release control rod (29)is
reconnected, the bevel fastener 
(30)must always
be replaced since it is damaged during disman-
tling 

[see 2.8.C].
Reattach all the connections, and then …

Check the brake [see 4.3]

Lift the wheels cover [see 2.5].

Dismantle the engine pulley [see 5.6] to release
the belt.

							5.8 REMOVAL OF THE CUTTING DECK
Removing the cutting deck facilitates all the over-
haul and replacement of hubs, bearings and blade
shafts.
With some practice and experience it is possible
to do this work with the deck still in position.
Pull out the external split pin (1)through the inspec-
tion hole in front of the seat and remove the pin 
(2)
from the inside, in order to disconnect the collector
channel 
(3).
Bring the cutting deck to position «1» and put a
40 mm block underneath the rear right wheel.
Pull out the split pin 
(4)in order to disconnect the
entire bracket 
(5)from the blade engagement lever
(6).
➤In mechanical drive models: slide the two
belt shifter bushes 
(7)up until the belt (8)is
released from the engine shaft pulley 
(9). 
➤In hidrostatic drive models:

Dismantle the engine pulley  [see 5.6] to
release the belt. 
Unscrew the nut 
(10)in order to pull the pin (11)out
of the front left lifting lever 
(12).
Pull the elastic split pin 
(13)of the pin (14)in the rear
right lever 
(15)and the elastic split pin (16)fastening
the pin to the front right lever 
(17). 
Take care not to touch the nuts and lock-nuts so
that they remain aligned for assembly
