2. Check the balance of the blade by putting it on a
blade balancer (Figure 71). 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 72). Repeat this
procedure until the blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Figure 72).
Important:
The curved part of the blade must
be pointing upward toward the inside of the
mower to ensure proper cutting.
2. Install the spring disk and blade bolt. The spring
disk cone must be installed toward the bolt head
(Figure 72).

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. Also, contact with the blade
could occur.
•
Never operate the lawn mower unless you
install a cover plate, a mulch plate, or a grass
chute and catcher.
•
Make sure the grass deflector is in the down
position.
1. Remove the locknut, bolt, spring and spacer holding
the deflector to the pivot brackets (Figure 73).
2. Remove the damaged or worn grass deflector.
3. Place the spacer and spring onto the grass deflector.
Place the
L
end of the spring behind the deck edge.
Note:
Make sure the
L
end of the spring is installed
behind the deck edge before installing the bolt as
shown in Figure 73
4. Install the bolt and nut.
5. Place the
J
hook end of the spring around the grass
deflector (Figure 73).
Important:
The grass deflector must be able to
lower down into position. Lift the deflector up
to test that it lowers into the full down position.
