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 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:
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.
A In setting up the front wheels, make sure that the
inflation valve stem of the tires face outward.
BRear Wheels
Rear tread width can not be adjusted.
A Always attach tires as shown in the drawings.
A If not attached as illustrated, transmission parts may
be damaged.
A When re-fitting or adjusting a wheel, tighten the bolts
and nuts to the following torques then recheck after
driving the tractor 200m (200yards) and thereafter
according to service interval.
