TIRES, WHEELS AND BALLAST
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.
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.
WHEEL ADJUSTMENT
To avoid personal injury:
A When working on slopes or when working with
trailer, set the wheel tread as wide as practical
for maximum stability.
A Support tractor securely on stands before
removing a wheel.
A Do not work under any hydraulically supported
devices. They can settle, suddenly leak down,
or be accidentally lowered. If necessary to work
under tractor or any machine elements for
servicing or adjustment, securely support them
with stands or suitable blocking beforehand.
A Never operate tractor with a loose rim, wheel,
or axle.
BFront Wheels (with two wheel drive)
Front tread width can be adjusted as shown with the
standard equipped tires.
To change the tread width
1. Remove the front axle mounting bolts and the tie-rod
mounting bolts.
2. Move the front axles (right and left) to the desired
position, and tighten the bolts.
3. Adjust the toe-in: [ 1 to 5 mm (0.04 to 0.2 in.)]
(See "Adjusting Toe-in" in "EVERY 200 HOURS" in
"PERIODIC SERVICE" section.)
