A blade thrown from the mower could seriously hurt or

mower with a worn or damaged blade.
A dull blade can be sharpened, but a blade that is excessively worn,

Blade Mounting Bolt Inspection
Inspect the blade bolts for any signs of damage
or looseness. If they are damaged, they must
be replaced.
If they appear loose, a torque wrench must be
used to accurately tighten the blade bolts to the
required torque. If you do not have a torque
wrench, take your lawn mower to an authorized
dealer to have the bolts replaced or tightened.
Use only Honda Genuine blade bolts and
special washers, since they are specifically
designed for this purpose. Replacement part
