Toro 22296, Operator'S Manual

Page: 21 / 28

WARNING
A worn or damaged accelerator can break, and a
piece of the accelerator could be thrown at 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 26 ).
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 28 A) and inner cutting edge radius ( Figure
28 B). The blade will remain balanced if you remove the same
amount of material from both cutting edges.
Figure 28
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 29 ).
Figure 29
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.
Adjusting the Blade-Brake
Cable
The blade-brake cable is adjusted at the factory; you do not
need to adjust it unless you are replacing the cable or the
blade-brake belt.
If you need to replace the cable, replace
both the cable and the belt at the same time.
1. Install a new blade-brake belt and assemble the
machine except for the 2 belt covers on the top of the
mower housing.
2. Install the new blade-brake cable, but do not tighten
the cable clamp on the top of the mower housing
(
Figure 30 ).
