DANGER
A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator's
or bystander's area, resulting in serious personal
injury or death.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade.
Inspecting the Blades
Service Interval: Before each use or daily
Before inspecting or servicing the blades, Park the
machine on a level surface, disengage the blade control switch
(PTO), and set the parking brake. Turn the ignition key to
Off. Remove the key.
1. Inspect the cutting edges (Figure 95). If the edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to Removing the Blades (page 58).
2. Inspect the blades, especially the curved area (Figure
95). If you notice any damage, wear, or a slot forming
in this area (Figure 95), immediately install a new blade.

Checking for Bent Blades
1. Disengage the blade control switch (PTO), move the
motion control levers to the neutral locked position
and set the parking brake.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Rotate the blades until the ends face forward and
backward (Figure 96).
Note: Measure from a level surface to the cutting
edge, position A, of the blades (Figure 96). Note this
dimension.
3. Wear/slot forming
4. Crack
1. Measure here from blade
to hard surface
4. Rotate the opposite ends of the blades forward.
5. Measure from a level surface to the cutting edge of the
blades at the same position as in step 3 above.
Note: The difference between the dimensions
obtained in steps 3 and 4 must not exceed 3 mm
(1/8 inch). If this dimension exceeds 3 mm (1/8 inch),
the blade is bent and must be replaced; refer to
Removing the Blades (page 58) and Installing the
Blades (page 59).
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.
2. Remove the blade bolt, curved washer, and blade from
the spindle shaft (Figure 97).
