TIRES
To avoid personal injury:
A
Do not attempt to mount a tire on a rim. This
should be done by a qualified person with the
proper equipment.
A
Always maintain the correct tire pressure.
Do not inflate tires above the recommended
pressure shown in the operator's manual.
A
Do not use tires other than those approved by
KUBOTA.
A
When optional different-diameter tires are fitted on the
machine, the travel speed display mode must be
changed. Otherwise the travel speed will not get
correctly displayed. Such mode switching is also
needed when the original tires are back on the
machine.
(See "PTO RPM / TRAVEL SPEED MONITOR" in
"OPERATING THE TRACTOR" section.)
B
Inflation Pressure
Though the tire pressure is factory-set to the prescribed
level, it naturally drops slowly in the course of time. Thus,
check it everyday and inflate as necessary.
A
Maintain the maximum pressure in front tires, if using
a front loader or when equipped with a full load of front
weights.
B
Dual Tires
Dual tires are not approved.
B
Treads
A
Front and rear treads can not be adjusted.
A
Always attach the wheels as shown in the factory-
shipment state, otherwise tractor parts may be
damaged.
A
When re-fitting or adjusting a wheel, tighten the bolts
to the following torques then recheck after driving the
tractor 200m (200 yards) and 10 times of shuttle
movement by 5 m (5 yards), and thereafter according
to service interval.
