SECTION 9: SERVICE
Tires
WARNING: Never exceed the maximum
inflation pressure shown on the sidewall of the
tire.
The recommended operating tire pressure is 10 psi for
the rear tires and 14 psi for the front tires. Refer to the
tire sidewall for exact tire manufacturer’s recommended
or maximum psi. Do not overinflate. Uneven tire
pressure could cause the cutting deck to mow
unevenly.
Fuse
A 20 amp fuse is installed in your tractor’s wiring
harness to protect the tractor’s electrical system from
damage caused by excessive amperage.
If the electrical system does not function, or your
tractor’s engine will not crank, first check to be certain
that the fuse has not blown.
It can be found under the hood mounted between the
dash panel and fuel tank on the right-hand support bar.
IMPORTANT: Always use a 20 amp fuse for
replacement.
WARNING: Before lubricating, repairing, or
inspecting, always disengage PTO, move
shift lever into neutral position, set parking
brake, stop engine and remove key to prevent
unintended starting.
Cutting Blades
WARNING: Be sure to shut the engine off,
remove ignition key, disconnect the spark
plug wire(s) and ground against the engine to
prevent unintended starting before removing
the cutting blade(s) for sharpening or
replacement. Protect your hands by using
heavy gloves or a rag to grasp the cutting
blade.
WARNING: Periodically inspect the blade
adapter and/or spindle for cracks or damage,
especially if you strike a foreign object.
Replace immediately if damaged
.
The blades may be removed as follows.
• Remove the deck from beneath the tractor, (refer to
DECK REMOVAL) then gently flip the deck over to
expose its underside.
• Place a block of wood between the center deck
housing baffle and the cutting blade to act as a
stabilizer. See Figure 19 .
• Use a 15/16" wrench to remove the hex flange nut
that secures the blade to the spindle assembly. See
Figure 19.
Figure 19
• To properly sharpen the cutting blades, remove
equal amounts of metal from both ends of the
blades along the cutting edges, parallel to the
trailing edge, at a 25° to 30° angle.
Figure 20
IMPORTANT: If the cutting edge of the blade has already
been sharpened to within 5/8" of the wind wing radius,
or if any metal separation is present, replace the blades
with new ones.
It is important that each cutting blade edge be ground
equally to maintain proper blade balance. A poorly
balanced blade will cause excessive vibration and may
cause damage to the tractor and result in personal
injury.
