Servicing the Mower Blades
Removing the Mower Blade
1. To remove the mower blade, use a 1” wrench
on the flats of the spindle shaft and remove the
mower blade mounting bolt with a 15/16” wrench
(Figure 26).
2. If there are no flats on the spindle shaft, wedge a
wooden block between the mower blade and the
mower deck housing to keep the mower blade
from turning.
Inspecting the Mower Blades
1. Remove the mower blade from the unit.
2. Inspect the mower blade (Figures 27 & 28).
Discard the mower blade if it has any of the
following conditions:
• Has more than .5” (12,7 mm) of the mower blade
metal removed from previous sharpening or wear
(D, Figure 27).
• The air lifts are excessively eroded (B & C, Figure
28) and the notch (C) is .25” (6,35 mm) deep or
greater.
• Mower blade is bent or broken.
3. If the cutting edges are not sharp or have nicks,
sharpen the blades.
CAUTION
Avoid injury! Mower blades are sharp.
• Always wear gloves when handling mower
blades or working near blades.
CAUTION
Avoid injury! A worn or damaged blade can
break, and a piece of the mower blade could
be thrown into the operator’s or bystander’s
area, resulting in serious personal injury or
death.
• Inspect the mower blade every 25 hours or at
least once a year.
• If the mower blade hits a solid object, stop
the engine immediately and inspect the mower
blade.
• Never weld or straighten bent mower blades.
