STEP 5: Attach Mower Discharge Deflector
CAUTION
• The discharge deflector must be installed before
operating the mower.
• Before installing the deflector, disconnect the
spark plug wire and keep the wire away from
the spark plug to prevent accidental starting.
• It will be necessary to reach below the blade
housing to install the discharge deflector.
Before doing so. put on heavy gloves to protect
your hands from the sharpened mower blade.
A. Parts Needed: (1) Discharge Deflector, (4) 1/4"-20
X 5/8" long Carriage Bolts, (4) 1/4" Lockwashers,
(4) 1 /4"-20 Hex Nuts.
B. It will be easier to install the deflector if you raise
the front of the mower a few inches off the ground and
then block the rear wheels.
C. Place the discharge deflector on the right side of
the mower deck so that the two square holes on the top
of the deflector are aligned with the square holes in the
top of the mower deck. Make sure that the right side of
the deflector overlaps the front wrap of the mower deck
and the left side of the deflector overlaps the rear mount­
ing bracket. See Photo 2-10.
D. Insert two 5/8" carriage bolts down through the
holes in the top of the deflector and loosely attach 1 /4"
lockwashers and hex nuts. See Photo 2-10.

safety cover removed for photo clarity.)
E. Insert a 5/8" carriage bolt from the inside of the
mower deck out through the holes in the bottom, left
side of the mounting bracket and the deflector. Loosely
attach a 1
14" lockwasher and hex nut. See Photo 2-10.
F. On the bottom, right side of the deflector (behind
the front wheel), insert a 5/8" carriage bolt from the in­
side of the mower deck out through the holes in the
front wrap and the deflector. Loosely attach a 1
14" lock-
washer and hex nut. See Photo 2-11. If necessary, loosen
the bumper nut (shown in Photo 2-11) to gain clearance
for the carriage bolt and nut. After adding the bolt and
nut, securely tighten the bumper nut.
G. Using a 7/16" wrench, tighten all four carriage bolts
securely.

STEP 6: Add Oil to Engine Crankcase
O CAUTION: The engine was shipped to you
“dry", and oil must be added to the crank­
case before the engine is started to avoid damag­
ing the engine.
A. Make sure that the engine is level.
B. Use a high quality detergent oil classified "For
Service; SE, SF, or SG." Above 40°F, use SAE 30.
From 0° to 40°F, use 5W-30 or 10W-30. (See the
engine owner's pamphlet for synthetic oil
recommendations.) No special additives should be
added to the oil. DO NOT MIX OIL WITH
GASOLINE.
C. The 5HP engine (22" mower) requires
approximately 20 ounces; the 8HP engine (24"
mower) requires approximately 36 ounces.
D. Clean the area around the oil fill hole before
removing the oil fill plug or dipstick.
IMPORTANT: Always stop engine before adding oil.
E. 8 HP ENGINE: Remove the dipstick by rotating it
counterclockwise. See Photo 2-12. Using a clean funnel,
slowly pour oil into the filler neck. While adding oil, fre­
quently check the level by replacing the dipstick and
rotating the cap until it is secure. Then remove the dip­
stick and check the oil level by reading the dipstick
markings (wipe the dipstick with a clean rag each time
before replacing it). Stop adding oil when the level
reaches the FULL mark. Do not overfill. ALWAYS MAIN­
TAIN THE OIL LEVEL AT THE FULL MARK ON THE
DIPSTICK.
