MAINTENANCE
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, spacer, blade insulator, and blade.
Place the new blade on the shaft against the corresponding
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 blade should be flat against the blade
posts.
Replace the blade insulator and spacer, making sure the
flat sides on each piece align and the straight sides of
the opening on the spacer are aligned with the straight
sides of the blade shaft.
NOTE: Make certain all parts are replaced in the exact
order in which they were removed.
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
600-650 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 blade, if needed.
