Checking For A Bent Blade; Removing And Installing The Cutter Blade(S) - Toro 30366 Operator's Manual

2. Remove the bearing from the wheel hub and allow the
bearing spacer to fall out (Fig. 31). Remove the bearing
from the opposite 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.
5. Slide the bearing spacer into the wheel hub. Push the
other bearing into the open end of the wheel hub to
captivate the bearing spacer inside the wheel hub.

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, 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. 32). 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 in. (3 mm). If the dimension exceeds 1/8 in.
(3 mm), the blade is bent and must be replaced; refer to
Removing the Cutter Blade, page 23.
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 (Fig. 33).
