Removing the Blades
Blades must be replaced if a solid object is hit, 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 nonconformance with safety standards.
1. Hold the blade end using a rag or a thickly-padded
glove.
2. Remove the blade bolt, the curved washer, and the
blade from the spindle shaft (Figure 94).

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (Figure 95).
Note: Maintain the original angle.
Note: The blade retains balance if the same amount
of material is removed from both cutting edges.

2. Check the balance of the blade by putting it on a blade
balancer (Figure 96).

Note: If the blade stays in a horizontal position, the
blade is balanced and can be used.

3. If the blade is not balanced, file some metal off the end
of the sail area only (Figure 94).
4. Repeat this procedure until the blade is balanced.
Installing the Blades
1. Install the blade onto the spindle shaft (Figure 97).
Important: The curved part of the blade must be
pointing upward toward the inside of the mower to
ensure proper cutting.
2. Install the spring disk and blade bolt (Figure 97).
Note: The spring-disk cone must be installed toward
the bolt head (Figure 97).
3. Torque the blade bolt to 115 to 150 N-m (85 to
110 ft-lb).
