TIRE AND WHEEL SERVICE
Visually inspect the tires before each use. Do not run the
tires under- or over-inflated which can cause tire damage.
The correct tire pressure for the front tires is 20 p.s.i.
(82.7 kpa) and rear wheels is 12 p.s.i. (137.9 kpa) (see
figure 25).
When reinstalling the wheel after service, be sure to torque
the nuts to 75 ft. lbs. (101 N•m). Drive 200-250 yards and
then re-torque.
BLADE MAINTENANCE
Inspect the blades daily for straightness, sharpness, and
balance. Replace the blades if they are cracked, worn, bent
or out of balance.
NOTE: Keep blades sharp. Mowing with dull blades will
cause poor cut performance. It will also put additional strain
on the engine by slowing the mower cutting speed.
To sharpen the blades, remove the blades by inserting a
block of wood and turning the blade bolt counter clockwise
(see figure 26).
Be sure to wear a thick glove or wrap the blade in a towel to
protect your hands from being cut. Insert the blades in a vise
and use a mill file or grinder. File the blade along the original
angle until the blade tip is at a 30° angle again.
CAUTION: Separation of a tire and rim can
cause an explosion that could cause serious
injury or death.
Check the tires for low pressure, cuts, bubbles,
damaged rims, or missing lug bolts and nuts.
Always use a clip-on chuck with an extension
long enough to allow you to stand on one side
of the wheel while inflating the tires. Do not
stand directly in front of the tire while inflating.
Never weld or heat a tire and wheel assembly.
The heat can cause the air inside of the tire to
expand and result in a tire explosion. Welding
also can structurally weaken or deform the
wheel.
CAUTION: Before removing the blades, be sure
the engine has stopped and the key has been
removed. The blades may be sharp. Wear gloves
or wrap them in a towel before handling them.
CAUTION: Never try to straighten a blade which
has been bent or try to weld a blade that is
cracked. Always replace with a new blade to
ensure safety.
