When removing the blades, use a 1-1/8 inch wrench
to hold the hex head of the spindle bolt when
loosening the hex nut securing the blade. A block of
wood may be placed between the deck housing and
the cutting edge of the blade to help in breaking loose
the hex nut securing the blade (Refer to Figure 52).

Use a 1-1/8" wrench to remove the hex flange nut that
secures the blade to the spindle assembly.
After replacing the blades, apply grease the exposed
threads at the bottom of the spindle bolts to prevent
rust buildup.
When replacing the blades, be sure they are installed
so that the wind wings are pointing upward toward the
top of the deck housing. Tighten the nuts to 90 to 110
ft-lbs. (122 to 149 N·m).
