Blade Maintenance

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 176 to 203 N-m (130 to 150 ft-lb).
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 (Figure
of the cutting unit to the cutting edge at the front
of the blade. Remember this dimension.
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
3 mm (1/8 inch). If the dimension exceeds 3
mm (1/8 inch), the blade is bent and must be
replaced; refer to
Cutter Blade(s) (page
Removing and Installing
the Cutter 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 be
sure of safety and optimum performance. Never use
replacement 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
109).
3. Install the blade, anti-scalp cup, and blade bolt.
Tighten the blade bolt to 115 to 149 N-m (85 to
