Inspecting the Blades
1. Inspect the cutting edges (Fig. 56). If the edges are not
sharp or have nicks, remove and sharpen the blades.
Refer to Sharpening the Blades on page 43.
2. Inspect the blades, especially the curved area (Fig. 56).
If you notice any damage, wear, or a slot forming in
this area (item 3 in Fig. 56), immediately install a new
blade.

Checking for Bent Blades
1. Rotate the blades until the ends face forward and
backward (Fig. 57). Measure from a level surface to
the cutting edge, position A, of the blades (Fig. 58).
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 inch (3 mm). If this dimension exceeds
1/8 inch (3 mm), the blade is bent and must be
replaced. Refer to Removing the Blades and Installing
the Blades.
Warning
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.
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
machine, use genuine TORO replacement blades.
Replacement blades made by other manufacturers may
result in non-conformance with safety standards.
1. Hold the blade end using a rag or thickly-padded
glove. Remove the blade bolt, washer, lock washer and
blade from the spindle shaft (Fig. 59).
