TIRES, WHEELS AND BALLAST
TIRES
To avoid personal injury or death:
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 recommended pressure in the
front tires, when using a front loader or when equipped
with a full load of front weights.
BDual Tires
Dual tires are not approved.
WHEEL ADJUSTMENT
To avoid personal injury or death:
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
Front tread width can not be adjusted.
A Do not turn front discs to obtain wider tread.
In setting up the front wheels, make sure that the
inflation valve stem of the tires face outward.
A When re-fitting or adjusting a wheel, tighten the bolts
to the following torques then recheck after driving the
tractor 200 m (200 yards) and 10 times of shuttle
movement by 5 m (5 yards), and thereafter according
to service interval. (See "MAINTENANCE" section.)
To avoid personal injury or death:
A Before jacking up the tractor, park it on a firm
and level ground and chock the rear wheels.
A Fix the front axle to keep it from swinging.
A Select jacks that withstand the machine weight
and set them up as shown below.
