Installing the Grass Deflector on 42 and 48 inch Side

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 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 move the power take off (PTO) to Off and rotate the ignition key to Off. Also remove the key and pull the wire off the spark plug(s).

2. Place the straight end of the spring into the small hole

in the discharge chute (Fig. 2).
