9.3 REPLACING OF FRONT
/ REAR WHEELS
9.3.1 Preliminary procedures
DANGER
Use a suitable lifting device.
Before changing the wheels it is necessary
to complete some preliminary operations:
1. Position the machine on a solid
and even surface that guarantees
stability of the machine.
2. Stop the machine;
3. Remove the key from the ignition;
4. Place the lifting device at the lifting
point close to the wheel to be
replaced (par. 9.3.2; par. 9.3.3).
5. Make sure the lifting device is perfectly
perpendicular to the ground.
9.3.2 Choice and positioning of the
jack on the rear wheels
Place some wooden wedges (fig. 31.A)
to the wheel base (fig. 31.B) to the side of
the wheel to be changed (fig. 30.C).
For models with rear collection:
• The maximum possible jack height
when closed is 110 mm. (fig. 32).
• Place the jack under the rear plate
(fig. 33.A) at 180 mm from the side edge.
For side discharge models:
• The maximum possible jack height
when closed is 110 mm. (fig. 34).
• Place the jack under the rear axle, in the
point indicated in the diagram (fig. 35.A).
NOTE
In this position the jack allows you to
only raise the wheel to be changed.
9.3.3 Choice and positioning of the
jack on the front wheels
1. Place some wooden wedges (Fig. 36.A)
to the wheel base (Fig. 36.B) behind
the wheel to be changed (Fig. 36.C).
2. The maximum possible jack height
when closed is 110 mm.
3. Place a square 10 x 10 cm wooden wedge
(Fig. 37.B) on the jack (Fig. 37.A).
WARNING
The wooden wedge prevents
damage to the front axle.
4. During this phase use your hand to keep the
wedge balanced correctly on the jack. Raise
the jack so that the wedge rests against the
chassis and structural parts (fig. 37.C).
NOTE
In this position the jack allows you
to raise the entire front axle.
9.3.4 Changing the wheel
SAFETY INSTRUCTIONS
Make certain the machine remains still
and stable during the lifting process. If you
notice anything out of the ordinary, lower
the jack immediately, check and resolve
any problems and lift the machine again.
1. Remove the cover (fig. 38.A).
2. Raise it enough to extract the wheel easily.
3. Using a screwdriver, remove
the snap ring (fig. 38.B) and the
shoulder washer (fig. 38.C).
4. Remove the wheel to be changed.
5. Coat the axle (fig. 38.D) with grease.
6. Mount the spare wheel.
7. Carefully replace the shoulder
washer and snap ring.
NOTE
Make sure the two rear wheels are the same
height (fig. 39.A) and that the difference
between the external diameters of the two
wheels (fig. 39.B) does not exceed 8-10
mm. On the contrary, to avoid uneven
mowing, the cutting-means assembly must
be aligned by an authorised Dealer.
