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. 

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.

A 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 is located under the hood mounted behind the top of 
the dash panel on the support bar.

 Always use a fuse with the same 

amperage capacity for replacement. 

Before servicing, repairing, or

inspecting, always disengage PTO, set
parking brake, stop engine and remove key to
prevent unintended starting.

Be sure to shut the engine off,

remove ignition key and disconnect the spark
plug wire(s) before removing the cutting
blade(s) for sharpening or replacement.
Protect your hands by using heavy gloves
when grasping the blade.

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 26), 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 18.

•

Use a 1-1/8" wrench to remove the hex flange nut 
that secures the blade to the spindle assembly. See 
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.

 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. 

The blade can be tested by balancing it on a round 
shaft screwdriver. Grind metal from the heavy side until 
it balances evenly. 

 When replacing the blade, be sure to 

install the blade with the side of the blade marked 
‘‘Bottom’’ (or with a part number stamped in it) facing 
the ground when the mower is in the operating position. 

Use a torque wrench to tighten the blade 

spindle hex flange nut to between 70 lbs-ft and 90 lbs-ft.
