CUTTING BLADE
When removing the cutting blade for sharpening or
replacement, protect hands by using heavy gloves or
a rag to grasp the cutting blade. Remove the bolt and
bell washer which hold the blade and adapter to the
engine crankshaft. Remove the blade and adapter from
the crankshaft.
If the blade or blade adapter needs replacing, remove
the two small bolts, lock washers and nuts which hold
the blade to the adapter.
A
WARNING: Periodically inspect the blade
adapter for cracks, especially if you strike
a foreign object. Replace when necessary.
FIGURE 13.
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. An unbalanced blade will
cause excessive vibration when rotating at high speeds,
may cause damage to the mower and could break,
causing personal injury.
It is recommended that the blade always be removed
from the adapter for the best test of balance. The blade
can be tested by balancing it on a round shaft
screwdriver. Remove metal from the heavy side until
it balances evenly.
Before reassembling the blade and the blade adapter
to the unit, lubricate the engine crankshaft and the inner
