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 68). Repeat this procedure
until the blade is balanced.

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 66).
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 66).
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 69).
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 69).
5.
Engage the blades. Ensure the blade brake pad no
longer contacts the pulley groove.

Replacing the Grass Deflector
WARNING
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 70). Remove
damaged or worn grass deflector.
