pressure shown in the operator's manual.

Inflation 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.

front tires, when using a front loader or when equipped
with a full load of front weights.

Dual Tires
Dual tires are not approved.

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

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.
B
