side of the wheel hub.
3. Check the bearings, spacer, and inside of the wheel
hub for wear. Replace any damaged parts.
4. To assemble the castor wheel, push the bearing into
the wheel hub. When installing the bearings, press
on the outer race of the bearing.

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 130
to 150 ft-lb (176 to 203 N⋅m).
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 90). Measure from the inside 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
2 and 3 must not exceed 1/8 inch (3 mm). If the
dimension exceeds 1/8 inch (3 mm), the blade is
bent and must be replaced; refer to Removing and
Installing the Cutter Blade.
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 (Figure 91).
3. Install the blade, anti-scalp cup, and blade bolt.
Tighten the blade bolt to 85 to 110 ft-lb (115 to 149
N⋅m).
