Check the blade(s). Keep a sharp edge on the blade(s). A blade
that is not sharp will cause the tips of the grass to become
brown.
If the quality of cut has not improved, replace the mower drive
belt. See "How To Replace The Mower Drive Belt". If replacing
the belt does not correct the problem, take the unit to a Sears
or other qualified service center.
Move the attachment clutch to the DISENGAGE
position,
Stop the engine. Disconnect the wire from the spark plug.
7.
Check the operation of the blade brake, Rotate the pulley with
your hand. Make sure the brake pad is pressed tightly against
the pulley (Figure 28).

ARNING:
If the brake pad does not press tightly
against the pulley, take the unit to a Sears or other qu-
alified service center.
8.
Move the attachment clutch to the ENGAGE position.
Check the pad for the blade brake, If the pad is excessively
worn or damaged, replace the brake pad assemblies. Correct
replacement parts and assistance are available from a Sears
service center.
10. Attach the wire to the spark plug. Mow for a short distance and
again check the operation of the attachment
clutch.
11.
When you move the attachment
clutch to the DISENGAGE
position, all movement will stop within five seconds. If there is
movement of the belt or the blades continue to rotate, engage
and disengage the attachment
clutch five times to remove
any excess rubber from a new mower drive belt, If you need
assistance, take the unit to a Sears or other qualified service
center.
