Checking for Bent Blades

1. Disengage the blade control switch (PTO), move the

motion control levers to the neutral locked position
and set the parking brake.

2. Stop the engine, remove the key, and wait for all

moving parts to stop before leaving the operating
position.

3. Rotate the blades until the ends face forward and

backward (Figure 95). Measure from a level surface
to the cutting edge, position

A

, of the blades

(Figure 95). Note this dimension.

Measure here from blade
to hard surface

Position A

4. Rotate the opposite ends of the blades forward.

5. Measure from a level surface to the cutting edge of

the blades at the same position as in step above.
The difference between the dimensions obtained in
steps and must not exceed 1/8 inch (3 mm). If
this dimension exceeds 1/8 inch (3 mm), the blade
is bent and must be replaced; refer to Removing the
Blades and Installing the Blades.

A blade that is bent or damaged could break
apart and could seriously injure or kill you or
bystanders.

Always replace bent or damaged blade with
a new blade.

Never file or create sharp notches in the
edges or surfaces of blade.

Removing the Blades

Blades must be replaced if a solid object is hit, if the
blade is out of balance or is bent. To ensure optimum
performance and continued safety conformance of
the machine, use genuine Toro replacement blades.
Replacement blades made by other manufacturers may
result in non-conformance with safety standards.

1. Hold the blade end using a rag or thickly-padded

glove.

2. Remove the blade bolt, curved washer, and blade

from the spindle shaft (Figure 96).
