Removing The Blades - Toro 30363N Operator's Manual

2. Move the throttle lever to the Slow position, 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 72). Measure from a level surface to
the cutting edge, position A, of the blades (Figure 72).
Note this dimension.

1. Measure here from blade
to hard surface
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 3 above.
The difference between the dimensions obtained in
steps 3 and 4 must not exceed 3 mm (1/8 inch). If this
dimension exceeds 3 mm (1/8 inch), the blade is bent
and must be replaced; refer to Removing the Blades
and Installing the Blades.
WARNING
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.
2. Position A
WARNING
Contact with a sharp blade can cause serious injury.
Wear gloves or wrap sharp edges of the blade with
a rag.
1. Hold the blade end using a rag or thickly-padded glove.
2. Remove the blade bolt, anti-scalp plate, and blade from
the spindle shaft (Figure 75).
Sharpening the Blades
WARNING
When sharpening blade, pieces of blade could be
thrown and cause serious injury.
Wear proper eye protection when sharpening
blades.
1. Sharpen the cutting edge at both ends of the blade
(Figure 73). Maintain the original angle. The blade
retains its balance if the same amount of material is
removed from both cutting edges.
1. Sharpen at original angle
2. Check the balance of the blade by putting it on a blade
balancer (Figure 74). If the blade stays in a horizontal
position, the blade is balanced and can be used. If the
blade is not balanced, file some metal off the end of
the sail area only (Figure 75). Repeat this procedure
until the blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Figure 75).
Important: The curved part of the blade must be
pointing upward toward the inside of the mower to
ensure proper cutting.
2. Install the anti-scalp plate and blade bolt (Figure 75).
