TIRES
WARNING
To avoid personal injury or death:
• Do not attempt to mount a tire on a rim. This
should be done by a qualified person with the
proper equipment.
• Always maintain the correct tire pressure.
Do not inflate tires above the recommended
pressure shown in the operator's manual.
IMPORTANT :
• Do not use tires other than those approved by
KUBOTA.
NOTE :
• When optional different-diameter tires are fitted
on the machine, the travel speed display mode
must be changed. Otherwise, the travel speed
will not be correctly displayed. Such mode
switching is also needed when the original tires
are back on the machine.
(See Setting the tire circumference on page 65.)
1. Inflation pressure
Although the tire pressure is factory-set to the
prescribed level, it naturally drops slowly in the course
of time. Thus, check it every day and inflate as
necessary.

WHEEL ADJUSTMENT
WARNING
To avoid personal injury or death:
• When working on slopes or when working with
a trailer, set the wheel tread as wide as practical
for maximum stability.
• Support the tractor securely on stands before
removing a wheel.
• Do not work under any hydraulically supported
devices. They can settle, suddenly leak, or be
accidentally lowered. If necessary to work
under the tractor or any machine elements for
servicing or adjustments, securely support
them with stands or suitable blocking
beforehand.
• Never operate the tractor with a loose rim,
wheel or axle.
1. Safe replacement of the wheel
The wheel is heavy. Take the following precautions
when removing the wheel.
1. Park the tractor on a solid, level place.
2. Apply the parking brake and use chocks.
3. In detaching the rear wheels, apply a wedge in
place to keep the front axle from oscillating.
4. Use a jack or the like that withstands the relevant
weight.
5. Use an appropriate tire remover.
6. Tighten the bolts and nuts to their specified torques.
