there is 1/8–3/16 inch (3mm–5mm) between the nut and
spacer (Fig. 51).
5. Engage the blades. Ensure the blade brake pad no

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.
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.
1. Remove the locknut, bolt, spring and spacer holding
deflector to the mounts (Fig. 53).
2. Straighten deflector mounts if they are bent (Fig. 53).
3. Install new deflector between mounts with spacer and
spring. Hook the front end of the spring around the
front deflector mount. Insert bolt through spacer and
secure with locknut. Confirm there is downward spring
force on deflector (Fig. 53).
4. Tighten the bolt and locknut until they lightly contact
the pivot brackets (Fig. 53).
Important
The grass deflector must be spring-loaded in
the down position. Lift the deflector up to test that it snaps
to the full down position.
