WARNING
A worn or damaged accelerator can break,
and a piece of the accelerator could be thrown
toward you or bystanders, resulting in serious
personal injury or death.
• Inspect the accelerator periodically for
wear or damage.
• Replace a worn or damaged accelerator.
Removing the Blade
1. Grasp the end of the blade using a rag or a
thickly padded glove.
2. Remove the blade nuts, the accelerator, and the
blade (Figure 25).
Sharpening the Blade
Service Interval: Every 50 hours—Sharpen or
replace the blade. Maintain it more
frequently if the edge dulls quickly in
rough or in sandy conditions.
File the top side of the blade to maintain its original
cutting angle (Figure 27A) and inner cutting edge
radius (Figure 27B). The blade will remain balanced if
you remove the same amount of material from both
cutting edges.
Figure 27
1. Sharpen the blade at this
angle only.

2. Maintain the original radius
here.
Balancing the Blade
1. Check the balance of the blade by placing
the center hole of the blade over a nail or
screwdriver shank clamped horizontally in a vise
(Figure 28).
Note:
You can also check the balance using a
commercially manufactured blade balancer.
2. If either end of the blade rotates downward, file
that end (not the cutting edge or the end near
the cutting edge) until neither end of the blade
drops.
Installing the Blade
1. Install a sharp, balanced Toro blade, the
accelerator, and the blade nuts. The sail of the
blade must point toward the top of the mower
housing for proper installation.
Note:
Torque the blade nuts to 20 to 37 N∙m
(15 to 27 ft-lb).
WARNING
Operating the machine without the
accelerator in place can cause the
blade to flex, bend, or break, resulting
in serious injury or death to you or to
bystanders.
Do not operate the machine without the
accelerator in place.
2. Return the machine to the operating position.
