Warning

Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death.

• Never remove the grass deflector from the

mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately.

• Never put your hands or feet under the mower.

• Never try to clear discharge area or mower

blades unless you release the bail and the power take off (PTO) is off. Rotate the ignition key to “OFF.” Also remove the key and pull the wire off the spark plug(s).
