Danger

Without the grass deflector 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

For optimum efficiency, check the level of the mower after

installation and periodically, to ensure that the blades are

1/8 in. (3 mm) lower in the front than in the rear.

Check and adjust the mower on a flat, level surface,

preferably concrete. Before checking the mower level, set

the air pressure in the front and rear tires as specified in the

tractor Operator’s Manual. Place the mower height-of-cut

lever to the middle cut position. Ensure that the two

adjustable front wheels are off of the ground.

1. Disengage the PTO, set the parking brake, lower the

attachment lift, stop the engine, and remove the ignition

key.
