Checking for a Bent Blade
After striking a foreign object, inspect the machine for
damage and make repairs before restarting and operating
the equipment. Torque all the spindle pulley nuts to
140–160 ft–lbs.
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. Block the
cutting unit to prevent it from accidentally falling.
2. Rotate the blade until the ends face forward and
backward (Fig. 63). Measure from the inside of the
cutting unit to the cutting edge at the front of the blade.
Remember this dimension.
Figure 63
3. Rotate the opposite end of the blade forward. Measure
between the cutting unit and cutting edge of the blade at
the same position as in step 2. The difference between
the dimensions obtained in steps 2 and 3 must not
exceed 1/8 in. (3 mm). If the dimension exceeds 1/8 in.
(3 mm), the blade is bent and must be replaced; proceed
to Removing the Cutting Unit Blade.
Removing the Cutting Unit
Blade
Replace the blade if a solid object is hit, the blade is out of
balance 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. Torque all the spindle pulley nuts to 140–160
ft–lbs.
1. Raise cutting unit to transport position, engage parking
brake, shut the engine off and remove key from
ignition.
2. Using a rag or thickly padded glove, grasp end of blade.
Remove blade bolt, lockwasher, anti–scalp cup and
blade from spindle assembly (Fig. 64).

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.
3. When assembling, make sure blade sail is facing up.
Torque the blade bolt to 140–165 ft.-lb. (190–224 N⋅m).
Inspecting and Sharpening the
Blade
After striking a foreign object, inspect the machine for
damage and make repairs before restarting and operating
the equipment. Torque all the spindle pulley nuts to
130–160 ft–lbs.
1. Raise cutting units to transport position, engage parking
brake, shut engine off and remove key from ignition
switch.
2. Carefully examine cutting ends of the blade, especially
where the flat and sail (curved part) meet (Fig. 65-A).
Since sand and abrasive material can wear the metal
connecting the flat and sail portions, check the blade
