Warning
A blade that is bent or damaged could break apart
and could seriously injure or kill you or
bystanders.
Always replace a bent or damaged blade with a
new blade.
Never file or create sharp notches in the edges
or surfaces of the blade.

Removing the Blades

Hold the blade end using a rag or thickly-padded glove.
Remove the retainer bolt with its washer and spacer, and
the shear bolts and locknuts from the blade retainer
(Fig. 44).
Installing the Blades
Important The blades are different for each side and
rotate in opposite directions forcing clippings to the center
rear of the mower. Align cutting edges properly when
installing. Sails of blades must point towards the top of the
deck.
