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 14. 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.
Figure 14
• 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 13.
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.
Lubrication
(Refer to Lubrication Chart in Figure 15.)
WARNING: Always stop engine and
disconnect spark plug wire before
cleaning, lubricating or doing any kind of
work on lawn mower.

Blade Control
• Lubricate the pivot points on the blade control
handle and the brake cable at least once a season
with light oil. The blade control must operate freely
in both directions.
Rear & Side Discharge Doors
• The torsion springs and pivot points should be
lubricated periodically with light oil to prevent any
rust or binding. Door must work freely.
Wheels
• The wheels require no lubrication. However, if the
wheels are removed for any reason, lubricate the
surface of the axle bolt and the inner surface of the
wheel with light oil. Engine oil may also be used.
Engine
• Follow engine manual for instruction and schedule
of lubrication.
NOTE: When tipping the unit, empty the fuel tank and
keep engine spark plug side up.
