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 94).

Sharpening the Blades
WARNING
When sharpening blade, pieces of blade could be
thrown and cause serious injury.
Wear proper eye protection when sharpening blade.
1.
Use a file to sharpen the cutting edge at both ends of
the blade (Figure 95). Maintain the original angle. The
blade retains its balance if the same amount of material
is removed from both cutting edges.

Sharpen at original angle
2.
Check the balance of the blade by putting it on a blade
balancer (Figure 96). 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 97). 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. The spring disk
cone must be installed toward the bolt head (Figure 97).
Torque the blade bolt to 85-110 ft-lb (115-150 N-m).
