Note:
The difference between the dimensions
obtained in steps
(1/8 inch). If the dimension exceeds 3 mm (1/8
inch), the blade is bent and must be replaced;

Blade(s) (page 74).
Removing and Installing
the Mower Blade(s)
The blade must be replaced if a solid object is hit, the
blade is out of balance, or if the blade is bent. Always
use genuine Toro replacement blades to ensure safety
and optimum performance.
1. Raise the mower deck to the highest position,
engage the parking brake, shut off the engine,
and remove the ignition key.
Note:
Block the mower deck to prevent it from
accidentally falling.
2. Grasp the end of the blade using a rag or
thickly-padded glove.
3. Remove the blade bolt, anti-scalp cup, and
blade from the spindle shaft

4. Install the blade, anti-scalp cup, and blade bolt
and tighten the blade bolt to 115 to 149 N∙m (85
to 110 ft-lb).
Important:
The curved part of the blade
must be pointing toward the inside of the
mower deck to ensure proper cutting.
Note:
After striking a foreign object, torque all
of the spindle-pulley nuts to 115 to 149 N∙m (85
to 110 ft-lb).

Inspecting and Sharpening
the Mower Blade(s)
Consider 2 areas when checking and servicing the
mower blade—the sail and the cutting edge. Both
cutting edges and the sail, which is the turned-up
portion opposite of the cutting edge, contribute to a
good quality of cut. The sail is important because it
lifts the grass up straight, thereby producing an even
cut. However, the sail gradually wears down during
operation. As the sail wears down, the quality of cut
degrades somewhat, although the cutting edges are
sharp. The cutting edge of the blade must be sharp
so that the grass is cut rather than torn. A dull cutting
edge is evident when the tips of the grass appear
brown and shredded. Sharpen the cutting edges to
correct this condition.
1. Position the machine on a level surface, raise
the mower deck, engage the parking brake, put
the traction pedal in
in the O
FF
remove the ignition key.
2. Examine the cutting ends of the blade carefully,
especially where the flat and curved parts of the
blade meet
Note:
Because sand and abrasive material
can wear away the metal that connects the
flat and curved parts of the blade, check the
blade before using the mower. If wear is noticed
(Figure 107), replace the blade.
