TYRES AND WHEELS
Countax Tractors are fitted with grassland tyres that are
designed to present a large area to the ground for grip and
are of soft profile to prevent marking your turf. They are of
thicker section and tougher than most 4 ply tyres.
Persistent punctures and tyre deflation are nevertheless a
problem experienced by around 5% of Countax customers.
This is not a problem just for Countax owners – it is shared
by the users of all types of off-road machinery fitted with
pneumatic tyres. In practically every case there is a
common cause – 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 -
so check and avoid these possible causes:
1. The rim of the wheel has been damaged – breaking the
seal on the tube-less tyre. There are two possible
solutions:
• If the damage is not severe, treat with Countax Tyre
Sealant (Pt No. 52903501).
• If the damage is significant – order a new wheel from
your dealer.
2. If you have Hawthorn, Blackthorn or Wild Rose in your
hedges - this will puncture any tyre. It makes sense to
check any area you intend to cut or drive over and to
remove any branches.
The long-term solution is to treat all four tyres with Countax
Tyre Sealant – follow the instructions on the bottle.
IF YOUR TYRES SPIN OR LOSE GRIP CHECK:
1. Are the tyres correctly inflated? – check pressures on
back page.
2. Are you going too fast for the conditions?
REMOVAL OF FRONT WHEEL - Fig 58
1. Apply Parking Brake.
2. Place chocks under all wheels that are to remain on the
ground.
3. Remove the hubcap.
4. Use a 3/4" socket/spanner and ratchet to slacken off the
wheel nut – do not remove!
5. Place a jack under the front axle (fig 58) and jack up until
the wheel to be removed is well clear of the ground.
6. Remove the nut and washers and keep safely.
7. Pull off the wheel carefully – Taking care not to dislodge
the Tractor from the jack.
When the tyre is repaired, replace the wheel preferably
using a new 1/2" Nyloc nut (Part No. 04822400). Tighten
to a torque setting of 5.25kg.m (38lb/ft).
REMOVAL OF REAR WHEEL - Fig 59 & 60
1. Apply Parking Brake.
2. Place chocks under the wheels that are to remain on the
ground.
3. Place the jack under the jacking point on the chassis
and raise until the wheel is well off the ground.
4. Remove the hubcap.
5. Using a flat ended screwdriver, lever off the ‘E’ clip and
remove the washers (fig 60).
6. Pull off the wheel carefully taking care not to dislodge the
tractor from the jack.
7. Remove the key from the wheel hub, first removing the
grease seal from the front of the hub using a small
screwdriver (keep safe with the key, ‘E’ clip and
washers).
When the tyre is repaired, fit the wheel onto the shaft; line
up keyways and tap in the key. Pull the wheel forward off
the shaft until the grease seal recess is just clear and refit
the seal. Then slide the wheel fully on the shaft. Reverse
instructions 1-6 to complete the job.
