1. Sharpen at original angle
2. Check the balance of the blade by putting it on a
blade balancer (Figure 62). If the blade stays in a
horizontal position, the blade is balanced and can be
used. If the blade is not balanced, file some metal off
the end of the sail area only (Figure 62). Repeat this
procedure until the blade is balanced.
1. Blade
Installing the Blades
1. Install the bolt, curved washer, and blade. Select the
proper number of spacer(s) for the height-of- cut,
and slide the bolt into the spindle (Figure 60).
Important: The curved part of the blade must
point upward toward the inside of the mower to
ensure proper cutting.
2. Install the remaining spacer(s) and secure them with
a thin washer and a nut (Figure 60).
3. Torque the blade bolt to 75-80 ft-lb (101-108 N•m).
Adjusting the Blade Brake
1. Disengage the PTO, turn the ignition key to off, and
remove the key.
2. Wait for all moving parts to stop before leaving the
operating position and then set the parking brakes.
3. If necessary, adjust the spring mounting bolts so that
the blade brake pad rubs against both sides of the
pulley groove (Figure 63).
4. Adjust the nut at the end of the blade brake rod until
there is 1/8-3/16 inch (3 mm -5 mm) between the
nut and spacer (Figure 63).
5. Engage the blades. Ensure the blade brake pad no
longer contacts the pulley groove.

Replacing the Grass Deflector
An uncovered discharge opening could allow
the lawn mower to throw objects in the
operator's or bystander's direction and result in
serious injury or death. Also, contact with the
blade could occur.
Never operate the lawn mower with the grass
deflector removed unless you install a cover
plate, a mulch plate, or a grass chute and
catcher.
1. Remove the locknut, bolt, spring and spacer holding
the deflector to the pivot brackets (Figure 64).
Remove damaged or worn grass deflector.
