• The blade can be tested by balancing it on a round
shaft screwdriver. 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). Lubricating the bolt holes, bolts
and inner surface of the nuts is also recommended.
• Install the blade adapter on the crankshaft with the
“star” away from the engine. 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 here.
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.
Replacing Rear Flap
• To remove rear flap, cut off the flat end of the wire
rod which secures it to the deck. See Figure 13.
• Attach the new flap and new rod to deck, bending
the ends of the new rod over to secure to deck.
Figure 13
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 build-up 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).
Lubrication
Blade Control
Lubricate the pivot points on the blade control handle
and the brake cable at least once a season with light oil.
See Figure 14. The blade control must operate freely in
both directions.
Rear Discharge Door
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 lubrication instructions.
