Inspecting the Mower Blades
DANGER
Thrown objects hazard
Avoid injury: a worn or damaged mower blade can break and
a piece of the blade could be thrown into the operator's area
or bystander's area resulting in serious personal injury or death.
• Inspect the mower blade every 25 hours or at least once
per year.
• If the mower blade hits a solid object, stop the engine
immediately and inspect the mower blades.
• Never weld or straighten bent mower blades.
1. Remove the mower blade from the unit. See Removing the
Mower Blades.
2. Inspect the mower blade (Figures 28 and 29). Discard the
mower blade if it has any of the following conditions:
• More than .5" (12,7 mm) of the mower blade metal has
been removed from previous sharpening or wear (A,
Figure 28)
• The air lifts are excessively eroded (A, Figure 29) and
the notch (B) is .25" (6,35 mm) deep or greater.
