Install the blade adapter on the crankshaft with the
“star” away from the engine. Refer to Figure 20.
Place the blade with the side marked bottom (or
with part number) facing away from the adapter.
Align the blade bell support over the blade with the
tabs in the holes of the blade and insert the hex
bolt. Tighten the hex bolt to the torque listed in the
“Blade Mounting Torque” section below.
Blade Mounting Torque
Center Bolt: 450 in. lbs. min., 600 in. lbs. max.
To ensure safe operation of your unit, all nuts and
bolts must be checked periodically for correct
tightness.
DECK
The underside of the mower deck should be
cleaned after each use to prevent a buildup of grass
clippings, leaves, dirt or other matter. If this debris is
allowed to accumulate, it will invite rust and
corrosion, and may cause an uneven discharge of
grass clippings at the next cutting.
The deck may be cleaned by tilting the mower and
scraping clean with a suitable tool (make certain the
spark plug wire is disconnected).
ENGINE
Refer to the separate engine manual for engine
maintenance instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and
follow instructions carefully.
Service air cleaner every 25 hours under normal
conditions. Clean every few hours under extremely
dusty conditions. Poor engine performance and
flooding usually indicates that the air cleaner should
be serviced. To service the air cleaner, refer to the
separate engine manual packed with your unit.
The spark plug should be cleaned and the gap reset
once a season. Spark plug replacement is recom-
mended at the start of each mowing season; check
engine manual for correct plug type and gap specifi-
cations.
Clean the engine regularly with a cloth or brush.
Keep the cooling system (blower housing area) clean
to permit proper air circulation which is essential to
engine performance and life. Be certain to remove all
grass, dirt and combustible debris from muffler area.
REAR FLAP REPLACEMENT
The rear flap is attached to the back of the mower
deck, and is designed to minimize the possibility that
objects will be thrown from the rear of the mower
toward the operator. If the rear flap becomes dam-
aged, replace as follows.
To remove the old rear flap, cut off the flat end of the
wire rod which secures it to the deck using a pair of
side-cutters. Attach the new rear flap using the new
rod provided with the rear flap, bending the ends of
the rod over to secure.
SECTION 11: OFF-SEASON STORAGE
The following steps should be taken to prepare lawn
mower for storage.
1. Clean and lubricate mower thoroughly as
described in the lubrication instructions.
2. Refer to engine manual for correct engine
storage instructions.
3. Coat mower’s cutting blade with chassis grease
to prevent rusting.
4. Store mower in a dry, clean area. Do not store
next to corrosive materials, such as fertilizer.
NOTE: When storing any type of power equipment
in an unventilated or metal storage shed, care
should be taken to rust-proof the equipment. Using
a light oil or silicone, coat the equipment, especially
cables and all moving parts.
