Maintenance

Replacing the Grass Deflector

1. Stop the engine, set the parking brake, remove
the key and disconnect the spark plug wire(s)
from the spark plug(s).
2. Remove the locknuts, bolts and springs holding
the deflector mounts to the pivot brackets
(Fig. 25).
3. If the pivot brackets need to be replaced, remove
the carriage bolts and cone locknuts holding the
old brackets to the top of the discharge opening,
then install the replacement pivot brackets. Make
sure the carriage bolt heads are on the inside of
the cutting unit (Fig. 25).
4. Install the deflector mounts onto the pivot
brackets with the bolts, springs and locknuts.
Make sure the straight ends of the springs are
positioned between the deflector mounts and the
grass deflector (Fig. 25).
5. Tighten the locknuts until they contact the pivot
brackets (Fig. 25).
IMPORTANT: The grass deflector must be
spring-loaded in the down position. Lift the
deflector up to test that it snaps to the full
down position.

Tire Pressure

Maintain the air pressure in the front and rear tires as
specified. Uneven tire pressure can cause uneven cut.
Check the pressure at the valve stem after every 50
operating hours or monthly, whichever occurs first
(Fig. 26). Check the tires when they are cold to get
the most accurate pressure reading.
Pressure: 13 psi (90 kPa) drive wheels and castor
wheels.
