SECTION 9: 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 beneath the
seat, mounted to the inside of the frame, near the
battery tray.
IMPORTANT:Always use a 20 amp fuse for
replacement.
WARNING:
Before servicing, repairing, or
inspecting,
always
disengage
PTO,
set
parking brake, stop engine and remove key to
prevent unintended starting.
Cutting Blades
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 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
Cutting DeckRemoval on page 27) 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 21.
•
Remove the hex flange nut that secures the blade
to the spindle assembly. See Figure 21.

Figure 21
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 22
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.
