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
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

•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.

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.
