TIRES
NOTE: Check tire pressure after every 50
hours of operation or weekly.
Tire inflation pressure affects the amount of
weight a tire can carry. Check the air pressure in
your Mower tires. If necessary, adjust the tire
pressure, being careful not to overinflate or
underinflate. Observe the following guidelines:
• Do not inflate a tire above the maximum
pressure shown on the tire. If the tire is not
marked, do not exceed the maximum
pressure shown in the Tire Inflation chart
found in this manual.
• Do not reinflate a tire that has been run flat or
seriously underinflated until the tire has been
inspected for damage by a qualified person.
• When checking tire pressure, inspect the tire
for damaged sidewalls and tread cuts.
Neglected damage leads to early tire failure.
WARNING: INFLATING OR SERVICING
TIRES CAN BE DANGEROUS. TRAINED
PERSONNEL SHOULD SERVICE AND/OR
MOUNT TIRES WHENEVER POSSIBLE.
If you must inflate or service tires, follow these
safety precautions to avoid injury or fatality.
• Make sure the rim is clean and free of rust.
• Lubricate both tire beads and rim flanges with
soap solution. Do not use oil or grease.
• Use a clip-on tire chuck with a remote hose
and gauge. This allows the operator to stand
clear of the tire while inflating.
• After seating the beads, adjust inflation
pressure to recommended operating
pressure.
• Do not inflate a tire unless the rim is mounted
on the Mower or is secured so that will not
move if the tire or rim should suddenly fail.
• Do not weld, braze, otherwise repair, or use a
damaged rim.
• Never attempt tire repairs on a public road or
highway.
• Use jack stands or other suitable blocking to
support the Mower while repairing tires.
• Ensure jack has adequate capacity to lift your
Mower.
• Place jack on a firm, level surface.
• Do not place any part of your body beneath
the Mower or start the engine while the
Mower is on the jack.
WHEEL BOLT TORQUE
Tighten the wheel bolts to the specified torque
anytime the wheel assembly is removed from
the mower or the wheel bolts are loosened.
Wheel Torque
74.5±9 N·m (760±90 kg-m)
NOTE: Torque for the wheels is the same for
front and rear axles.
Check wheel bolt torque daily until torque
stabilized.
