Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the
blade control (PTO) and set the parking brake. Turn
the ignition key to “OFF” to stop the engine. Remove
the key and disconnect the spark plug wire(s) from
the spark plug(s).
Inspecting the Blades
1. Inspect the cutting edges (Fig 37). If the edges are not
sharp or have nicks, remove and sharpen the blades.
Refer to Sharpening the Blades on page 32.
2. Inspect the blades, especially the curved area (Fig. 37).
If you notice any damage, wear, or a slot forming in
this area (item 3 in Fig. 37), immediately install a new
blade.

Checking for Bent Blades
1. Rotate the blades until the ends face forward and
backward (Fig. 38). Measure from a level surface to
the cutting edge, position “A”, of the blades (Fig. 39).
Note this dimension.

2. Rotate the opposite ends of the blades forward.
3. Measure from a level surface to the cutting edge of the
blades at the same position as in step 1. The difference
between the dimensions obtained in steps 1 and 2 must
not exceed 1/8 in. (3 mm). If this dimension exceeds
1/8 in. (3 mm), the blade is bent and must be replaced.
Refer to Removing the Blades, and Installing the
Blades on page 32.
A blade that is bent or damaged could break
apart and could seriously injure or kill you or
bystanders.
• Always replace bent or damaged blade with a
new blade.
• Never file or create sharp notches in the edges
or surfaces of blade.
Warning
Removing the Blades
Blades must be replaced if a solid object is hit, if the
blade is out of balance or is bent. To ensure optimum
performance and continued safety conformance of the
