SECTION9: SERVICE
Tires
WARNING: Never exceed the maximum
inflation pressure shown on the sidewall of the
tire.
The recommended operating tire pressure is
approximately 10 psi for the rear tires and 14 psi for the
front tires. 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
tractor's seat, mounted to the inside of the frame near
the battery tray.
IMPORTANT:Always use a 20 amp fuse for
replacement.
_, ARNING: Before servicing, repairing, or
inspecting, always disengage PTO, set
parking brake, stop engine and remove key to
prevent unintended starting.
CuttingBlades
WARNING: Be sure to shut the engine off,
and remove the ignition key to prevent
unintended starting before removing the
cutting blade(s) for sharpening or
replacement. Protect your hands by using
heavy gloves when grasping the blade.
_, ARNING: Periodically inspect the bladeadapter 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
CuttingDeckRemovalon page 28) then carefully 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 23.
• Remove the hex flange nut that secures the blade
to the spindle assembly by turning it counter-
clockwise. See Figure 23.

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.

Seperation
Figure 24
IMPORTANT:If the cutting edge of the blade has already
been sharpened, 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.
