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 27).

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.
WARNING
Do not try to straighten a blade that is bent,
and never weld a broken or cracked blade.
Always use a new blade to ensure continued
safety certification of the product.

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. Raise the cutting unit to the highest position, shut the
engine off, and engage the parking brake. Block the
cutting unit to prevent it from accidentally falling.
2. Examine the cutting ends of the blade carefully,
especially where the flat and curved parts of the blade
meet (Figure 28). 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 28), replace the
blade; refer to Removing the Cutting Blade.

WARNING
If the blade is allowed to wear, a slot will form
between the sail and flat part of the blade
(Figure 28). Eventually, a piece of the blade
may break off and be thrown from under the
housing, possibly resulting in serious injury to
yourself or bystanders.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade with a
new Toro blade to ensure continued safety
certification of the product.
3. Examine the cutting edges of all blades. Sharpen the
cutting edges if they are dull or nicked. Sharpen only
the top side of the cutting edge and maintain the
