Removing the Blades
Replace a blade if it hits a solid object, if the blade is out
of balance, or if the blade 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 47 ).

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (
Figure 48 ).
Note:
Maintain the original angle.
Note:
The blade retains its balance if you remove the
same amount of material from both cutting edges.

1. Sharpen at the original angle.
2. Check the balance of the blade by putting it on a blade
balancer (
Figure 49 ).
Note:
If the blade stays in a horizontal position, the
blade is balanced and ready to use.
Note:
If the blade is not balanced, file some metal off
only the end of the sail area ( Figure 48 ).

3. Repeat this procedure until the blade is balanced.
Installing the Blades
1. Install the blade onto the spindle shaft ( Figure 47 ).
Important:
The curved part of the blade must
point upward toward the inside of the mower to
ensure proper cutting.
2. Install the curved washer (cupped side toward the
blade) and the blade bolt (
Figure 47 ).
3. Torque the blade bolt to 47 to 88 N·m (35 to 65 ft-lb).
Leveling the Mower Deck
Ensure that the mower deck is level any time you install the
mower deck or when you see an uneven cut on your lawn.
Check the mower deck for bent blades prior to leveling;
remove and replace any bent blades; refer to the
Checking for
Bent Blades (page 37) before continuing.
Level the mower deck side-to-side before adjusting the
front-to-rear slope.
Requirements:
•
The machine must be on a level surface.
•
All 4 tires must be properly inflated; refer to Checking
the Tire Pressure (page 35) .
Leveling from Side to Side
1. Park the machine on a level surface and disengage the
blade-control switch.
2. Move the motion-control levers outward to the P
ARK
position, shut off the engine, remove the key, and
wait for all moving parts to stop before leaving the
operating position.
3. Set the height-of-cut lever to middle position.
4. Carefully rotate the blade(s) so that they are all side to
side (
Figure 50 and Figure 51 ).
