Removing and Installing the
Blade(s)
The blade must be replaced if a solid object is hit, the
blade is out-of-balance, worn, or bent. Always use
genuine Toro replacement blades to ensure safety and
optimum performance. Never use blades made by other
manufacturers because they could be dangerous.
1. Raise the cutting unit to the highest position, engage
the parking brake, stop the engine, and remove the
ignition key. Block the cutting unit to prevent it from
accidentally falling.
2. Grasp the end of the blade using a rag or thickly
padded glove. Remove the blade bolt, anti-scalp cup,
and blade from the spindle shaft (Figure 30).

3. Install the blade-sail facing toward the cutting
unit-with the anti-scalp cup and blade bolt. Tighten
the blade bolt to 85-110 ft-lb (115-149 N-m).
Important: The curved part of the blade must
be pointing toward the inside of the cutting unit
to ensure proper cutting.

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.
• Do not try to straighten a blade that is bent.
• Never weld a broken or cracked blade.
• Replace a worn or damaged blade with a
new Toro blade to ensure continued safety
certification of the product.
Two areas must be considered when checking and
servicing the cutting blade: the sail and the cutting edge.
Both cutting edges and the sail, which is the turned up
portion opposite the cutting edge, contribute to a good
quality-of-cut. The sail is important because it pulls grass
up straight, thereby producing an even cut. However,
the sail will gradually wear down during operation, and
this condition is normal. As the sail wears down, the
quality-of-cut will degrade 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
cutting unit, engage the parking brake, put the
traction pedal in neutral, put the PTO lever in
the Off position, stop the engine, and remove the
ignition key.
2. Examine the cutting ends of the blade carefully,
especially where the flat and curved parts of the
blade meet (Figure 31). Since 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 machine. If wear is noticed
(Figure 31), replace the blade; refer to Removing the
Cutting Blade.
