Tyres (Fig. 54)
Check tyre pressures every 100
hours.
Warning
Tyre tread and ply rating or load
index must match. Do not fit a radial one
side and a crossply on the other. Check
that the tyre pressures are correct for
the particular operation to be performed.
These simple rules, if followed carefully,
will ensure maximum tyre life.
Fig. 54:
Check and adjust the front and rear
tyre pressure and inspect the tread and
side walls for damage (Fig. 54).
Note
After changing the oil and filter, run
the engine and check for leaks, then re-
check the transmission dipstick oil level
and if necessary, top up.
1. The tyre pressures listed are maxima
and can be used in safety, at all times,
without danger of sidewall rippling. In
certain conditions the pressures may
be lowered, particularly where the
loads are light resulting in the tyre
treads failing to self clean. If the tyre
pressures are reduced, have someone
observe the tractor whilst working.
Rippling of the sidewalls can cause
rapid and severe tyre damage.
2. Keep oil, grease and strong alkaline or
acid fertilisers away from tyres to pre-
vent deterioration of the rubber.
3. Have any small sidewall or tread splits
or cuts re-vulcanised as soon after
they occur as possible. This extends
the life of the tyre.
4. If bolt-on weights are fitted, raise the
pressures to suit the weight fitted,
consult ITMCO Dealer.
5. Always drive slowly 20 Km/hr (12 mile/
hr) on the road if the tyre pressures
have been lowered for ploughing.
6. For maximum efficiency if ploughing
with crossply tyres, never use tyres
more than a third to half worn.
