TIRES, WHEELS, AND BALLAST
TIRES
WARNING
To avoid personal injury or death:
• Do not try to mount a tire on a rim. Only a
qualified person with the proper equipment
should mount a tire on a rim.
• Always keep the correct tire pressure. Do not
inflate the tires above the recommended
pressure shown in the Inflation pressure of tires
on page 88.
IMPORTANT :
• Do not use tires other than those approved by
Kubota.
1. Inflation pressure of tires
Though the tire pressure is factory-set to the prescribed
level, it naturally drops slowly in the course of time.
Thus, check the tire pressure everyday and inflate as
necessary.

NOTE :
• Keep the maximum pressure in front tires, if
using a front loader or when equipped with a
full load of front weight.
2. Dual tires
You can not use the dual tires.
Dual tires are not approved.
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. Front wheels
WARNING
To avoid personal injury or death:
• Before jacking up the tractor, park it on a firm
and level ground and chock the rear wheels.
• Fix the front axle to keep it from pivoting.
• Select the jacks that withstand the machine
weight and set them up as shown in the
following figure.
