3. Remove one bearing retainer from the wheel hub and
allow the bearing to fall out. Remove the bearing
retainer from the opposite side of the wheel hub
(Figure 19).
4. Inspect the bearing, spanner bushing, and wheel for
wear. Replace worn or damaged parts.
5. To assemble the parts, slide the spanner bushing
through the hub assembly.
6. Mount the castor wheel assembly and washers between
the fork and insert the bolt and locknut. Tighten the
bolt and locknut until the spanner bushing and washers
bottom out against the inside of the castor fork.
7. Pump grease through the grease fitting on the wheel
until the bearing is greased thoroughly.

Checking for a Bent Blade

1. Position the machine on a level surface, raise the cutting
unit, engage the parking brake, put the traction pedal
in neutral, the PTO lever in the Off position, shut the
engine off, remove the ignition key, and disconnect the
wires from the spark plugs. Block the cutting unit to
prevent it from accidentally falling.
2. Rotate the blade until the ends face forward and
backward. Measure from the inside of the cutting unit
to the cutting edge at the front of the blade (Figure 20),
and remember this dimension.

5. Roller bearing
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 3 mm (1/8 inch). If the dimension exceeds
3 mm (1/8 inch), replace the blade because it is bent;
refer to Removing the Cutting Blade.

Removing the Cutting Blade

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.
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.
1. Position the machine on a level surface, raise the
cutting unit, engage the parking brake, put the traction
pedal in neutral, the PTO lever in the Off position,
shut the engine off, 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 21).
