WARNING:
If raising the mower to access the blades, make sure the
mower is properly secured and the parking brake is set
before proceeding. Failure to properly secure the mower
could cause it to fall, resulting in death or possible seri-
ous personal injury.
Wedge a block of wood between the blade and mower
deck to prevent the blade from turning.
Loosen the blade nut by turning it counterclockwise (as
viewed from bottom of mower) using a 15 mm wrench or
socket (not provided).
Remove the blade nut, spring washer, and blade.
Place the new blade on the shaft against the correspond-
ing blade posts. Ensure blade is properly seated with shaft
going through center blade hole and the two blade posts
inserted into their respective holes on the blade. Make
sure it is installed with the curved ends pointing up toward
the mower deck and not down toward the ground. When
seated properly, the straight sides should be aligned and
the blade should be flat against the blade posts.
Replace the spring washer, then thread the blade nut on
the shaft and finger tighten.
Torque the blade nut down clockwise using a torque
wrench (not provided) to ensure the bolt is properly
tightened. The recommended torque for the blade nut is
435 - 470 in. lbs.
WARNING:
Ensure blade is properly seated and the blade nut is
tightened to the torque specifications above. Failure to
properly attach the blade could cause it to come loose
and result in possible serious personal injury.
Repeat with second and third blades, if needed.
