Danger

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 the rotating mower blades 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 the 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 wires off of the spark plugs.

Mower Belt Routing

Route the mower belt as shown in Fig. 3. Ensure that you install the belt on the lower mower deck pulley.
