SECTION 10:  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 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 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.
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 
Cutting Deck Removal 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 18.
• Use a 1-1/8" wrench to remove the hex flange nut 
that secures the blade to the spindle assembly. See 
Figure 18.
Figure 18
• 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 19
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.
