Blade Care
WARNING: When removing the
cutting blade for sharpening or
replacement, protect your hands
with a pair of heavy gloves or use
a heavy rag to hold the blade.
Periodically inspect the blade adapter for
cracks, especially if you strike a foreign object.
Replace when necessary. Follow the steps
below for blade service.
1. Allow the engine to run until it is out of
fuel. Do not attempt to pour fuel from the
engine. Disconnect spark plug wire. Refer
to Engine Operator’s Manual.
2. Turn mower on its side making sure that
the air filter and the carburetor are facing
up.
3. Remove bolt (a) and blade bell
support (b) which hold the blade and the
blade adapter to the engine crankshaft.
See Figure 4-3.
4. Remove blade (c) and adapter (d) from
the crankshaft. See Figure 4-3.

5. Remove blade from the adapter for
testing balance. Balance the blade on
a round shaft screwdriver to check.
Remove metal from the heavy side until
it balances evenly. When sharpening the
blade, follow the original angle of grind.
Grind each cutting edge equally to keep
the blade balanced.
WARNING: An unbalanced blade
will cause excessive vibration
when rotating at high speeds. It
may cause damage to mower and
could break causing personal
injury.
6. Lubricate the engine crankshaft and the
inner surface of the blade adapter with
light oil. Slide the blade adapter (d) onto
the engine crankshaft. Place the blade
on the adapter such that the side of the
blade marked “Grass Side” (or with part
number) faces the ground when the
mower is in the operating position. Make
sure that the blade is aligned and seated
on the blade adapter flanges.
See Figure 4-3 inset.
7. Place blade bell support (b) on the
blade (c). Align notches on the blade bell
support with small holes in blade.
8. Replace hex bolt (a) and tighten hex
bolt to torque: 450 in-lb (min.), 600 in-lb
(max.).
To ensure safe operation of your mower,
periodically check the blade bolt for correct
torque.
