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.)
BInflation 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.
