• Remove the bolt and blade support or bell washer
which hold the blade and adapter to the engine
crankshaft. See Figure 18. Remove the blade and
adapter from the crankshaft.

• When sharpening the blade, follow the original
angle of grind as a guide. It is extremely important
that each cutting edge receives an equal amount of
grinding to prevent an unbalanced blade.
NOTE: An unbalanced blade will cause excessive
vibration when rotating at high speeds and may cause
damage to the mower and/or personal injury.
• The blade can be tested by balancing it on a round
shaft screwdriver. See Figure 19. Remove metal
from the heavy side until it balances evenly. It is
recommended that the blade always be removed
from the adapter for the best test of balance.

• Before reassembling the blade and the blade
adapter to the unit, lubricate the engine crankshaft
and the inner surface of the blade adapter with light
oil (or engine oil). Also lubricate the bolt holes, bolts
and inner surface of the nuts.
• Install the blade adapter on the crankshaft with the
“star” away from the engine. Refer to Figure 18.
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.
IMPORTANT:
To ensure safe operation, all nuts and
bolts must be checked periodically for correct tightness.
Deck Care
NOTE: We do not recommend the use of pressure
washers or garden hose to clean your unit.These may
cause damage to electric components spindles,
pulleys, bearings or the engine. The use of water will
shorten life of the mower and reduce its serviceability.
• 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.
Replacing Rear Flap
• To remove rear flap, cut off the flat end of the wire
rod which secures it to the deck. See Figure 20.
• Attach the new flap and new rod to deck, bending
the ends of the new rod over to secure to deck.
