TYRES
Inflation and Service
lUpon receiving your tractor, check the air
pressure in the tyres as indicated in the
tables.
lCheck the tyre pressure every 50 hours, or
weekly.
lTyre inflation pressure affects the amount of
weight which a tyre may carry. Locate the
tires for your tractor in the “Tyre inflation vs.
Permissible Load” chart on page 27. Do not
over-or-under inflate the tyres.
lDo not inflate a tyre above the manufacturer’s
maximum pressure shown on the tyre or the
maximum pressure shown in the “Tyre
Inflation vs. Permissible Load” chart, page 27
if the tyre is not marked.
lDo not re-inflate a tyre that has been run flat
or seriously under-inflated until the tyre has
been inspected for damage by a qualified
person.
WARNING: Inflating or servicing tyres
can be dangerous. Trained personnel
should be called to service and/or
mount tyres when possible. In any
event to avoid possible serious or fatal
injury, follow the safety precautions
below.
lWhen checking tyre pressure, inspect the tyre
for damaged side walls and tread cuts.
Neglected damage will lead to early tyre
failure.
lBe sure the rim is clean and free of rust.
lLubricate both tyre beads and rim flanges with
soap solution’. Do not use oil or grease.
lUse a clip-on tyre chuck with a remote hose
and gauge which allows the operator to stand
clear of the tyre while inflating it.
lNEVER INFLATE TO OVER 35 psi (241 kPa)
TO SEAT BEADS. If beads have not seated
by time pressure reaches 35 psi deflate the
assembly, reposition tyre on rim, relubricate
both tyre beads and rim flanges and re-
INFLATE. INFLATION BEYOND 35 PSI with
unseated beads may break the bead or rim
with explosive force sufficient to cause
serious injury.
lAfter seating the beads, adjust inflation
pressure to recommended operating
pressure.
lDo not inflate a tyre unless the rim is mounted
on the tractor or is secured so that it will not
move if the tyre or rim should suddenly fail.
lDo not weld, braze, otherwise repair, or use a
damaged rim.
lNever attempt tyre repairs on a public road or
highway.
lUse jack stands or other suitable blocking to
support the tractor while repairing tires.
lInsure jack has adequate capacity to lift your
tractor.
lInsure jack is placed on a firm level surface.
lDo not put any part of your body under the
tractor or start the engine while the tractor is
on the jack.
