Maintenance
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.
Hold the blade bolt with a wrench. Remove the nut,
blade bolt, cone washer, blade, spacers and thin
washer from the spindle (Fig. 33).

Sharpening the Blades
1.
Use a file to sharpen the cutting edge at both
ends of the blade (Fig. 34). Maintain the original
angle. The blade retains its balance if the same
amount of material is removed from both cutting
edges.

Check the balance of the blade by putting it on a
blade balancer (Fig. 35). If the blade stays in a
horizontal position, the blade is balanced and can
be used. If the blade is not balanced, file some
5
metal off the end of the sail area only (Fig. 34).
Repeat this procedure until the blade is balanced.

Installing the Blades
1.
Place the blade onto the bolt, over cone washer.
Select proper number of spacer(s) for
height-of-cut and slide bolt into spindle (Fig.
33).
IMPORTANT: The curved part of the blade
must be pointing upward toward the inside of
the mower to ensure proper cutting.
2.
Install remaining spacer(s) and secure with thin
washer and nut (Fig. 33).
3.
Torque the blade bolt to 75–80 ft. lb.
(101–108 N m).
