NOTE: Blowout reduction kit (AM124031) is used to
provide sufficient lip surface around deck to
install conventional blowout reduction kit like
on 48/54” decks.
Reason:
Grass blows out front of deck. Seems worse when
mulch kit has been installed.
Procedure:
1. If deck is equipped with a mulch kit, start with
adjustable screen fully raised. This will allow more
airflow out discharge chute.
2. Level the mower front-to-rear as instructed in
machine operators manual.
3. If mulching leaves, lower adjustable screen only as
much as needed for satisfactory mulching.
4. Other items to check:
—Engine fast idle speed set to specification.
—Blades sharp and underside of deck clean.
—Be sure ground speed is not too fast for mowing
conditions.
—Observe the 1/3rd cut rule.
—Be sure deck is properly leveled side-to-side.
—Review information on mulching tips.
