WARNING: To prevent an injury, the attachment
clutch must operate correctly.
1. Stop the engine. Disconnect the wire from the spark plug.
2. Before you adjust the attachment clutch, check and level the
mower housing. See "How To Level The Mower Housing."
Make sure the mower housing is level before go to the next
step.
3. Set the height of the mower housing in the lowest position.
4. Move the attachment clutch to the DISENGAGE position
(Figure 17).

engages, there must be 1/8" to 3/8" (3mm to 9mm) of free
movement.
6. If an adjustment is needed, disconnect the clevis from the
pivot rod and bracket assembly (Figure 18). Turn the clevis
clockwise to decrease the free movement of the attachment
clutch. Turn the clevis counterclockwise to increase the free
movement.

Move the attachment clutch to the DISENGAGE position.
Check the free movement of the attachment clutch.

your hand. Make sure that the blade brake pad presses tightly
against the pulley.

the pad for the blade brake. If the pad is excessively worn or
damaged, replace the brake pad assembly. Correct
replacement parts and assistance are available from an
authorized service center.
