Cutting Blades
WARNING:
remove ignition key, disconnect the spark plug
wire(s) and ground against the engine to
prevent unintended starting before removing
the cutting blade(s) for sharpening or
replacement. Protect your hands by using
heavy gloves or a rag to grasp the cutting
blade.
WARNING:
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

Use a 15/16" wrench to remove the hex flange nut
that secures the blade to the spindle assembly. See
Figure 19.
Be sure to shut the engine off,
Periodically inspect the blade

Wood Block
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. See Figure 20.
Worn Blade Edge
Sharpen Edge Evenly
If the cutting edge of the blade has already
IMPORTANT:
been sharpened to within 5/8" of the wind wing radius,
or if any metal separation is present, replace the blades
with new ones. See Figure 20.
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
IMPORTANT:
spindle hex flange nut to between 70 foot-pounds and
90 foot-pounds.
Tires
WARNING:
inflation pressure shown on the sidewall of the
tire.
The recommended operating tire pressure is 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 may cause the cutting deck to mow unevenly.
