Troubleshooting (Tyres & Wheels)
Persistent flat tyres
Like all garden machinery, the most common cause of
punctures are THORNS! Blackthorn, Hawthorn and Rose
are usually at the bottom of the problem and will puncture
any tyre not fitted with very expensive guards. There are
less expensive ways to overcome this problem and it is
advisable to check and avoid these possible causes:
The rim of the wheel has been damaged causing the seal
on the tube-less tyre to be broken. There are two solutions:
p
If the damage is significant it is necessary to order a new
wheel from your dealer.
p
If you have Hawthorn, Blackthorn or Wild Rose in your
garden – this will puncture any tyre. It makes sense to
check any area you intend to cut or drive over and to
remove any branches.
If your tyres spin or lose grip, check:
p
That all tyres are inflated to their correct pressures (See
pages 25-27).
p
Are you going too fast for the conditions?
Removal of front wheel
(Fig. 46)
p
Apply Parking Brake.
p
Place chocks under the wheels that are to remain on the
ground.
p
Remove the plastic hubcap.
p
Use a 19 mm socket/spanner to loosen the wheel nut
whilst on the ground – DO NOT REMOVE.
p
Place a jack under the front axle at the jacking point
Fig. 46 (on the side appropriate to the wheel that is to be
removed). Jack the tractor up until the wheel to be removed
is well clear of the ground.
p
Remove the wheel nut and washer and keep safe.
p
Taking care not to dislodge the tractor from the jack, pull
the wheel off. When the tyre is repaired, replace the wheel
preferably using a new M12 Nyloc nut. Tighten to a torque
setting of 5.25kg.m (38lb/ft).
Check to ensure wheel turns freely.

the side appropriate to the wheel that is to be removed).
Jack the tractor up until the wheel to be removed is well
clear of the ground.
p
Remove the wheel nuts using a 19 mm spanner/socket.
Once removed, keep safe and remove the wheel.
p
When replacing the wheel re-tighten the nuts to
5.25kg.m (38lb/ft).
