Blade Maintenance

Blade Safety

•
Inspect the blade periodically for wear or damage.
•
Use care when checking the blades. Wrap the
blades or wear gloves, and use caution when
servicing the blades. Only replace or sharpen the
blades; never straighten or weld them.
•
On multi-bladed machines, take care as rotating 1
blade can cause other blades to rotate.

Servicing the Blade

Removing and Installing the
Cutting-Unit Blade(s)
Replace the blade if it hits a solid object, is out
of balance, or is bent. Always use genuine Toro
replacement blades to ensure safety and optimum
performance.
1. Park the machine on a level surface, raise the
cutting unit to the highest position, engage the
parking brake, shut off the engine, and remove
the key.
Note:
Block the cutting unit to prevent it from
accidentally falling.
2. Grasp the end of the blade using a rag or
thickly-padded glove.
3. Remove the blade bolt, anti-scalp cup, and
blade from the spindle shaft

4. Install the blade, anti-scalp cup, and blade bolt
and tighten the blade bolt to 115 to 149 N∙m (85
to 110 ft-lb).
Important:
The curved part of the blade
must be pointing toward the inside of the
cutting unit to ensure proper cutting.
Note:
After striking a foreign object, torque all
spindle-pulley nuts to 115 to 149 N∙m (85 to 110
ft-lb).

Inspecting and Sharpening the
Blade
Note:
Check the blade before using the machine.
Sand and abrasive material can wear away the metal
that connects the flat and curved parts of the blade. If
you notice wear, replace the blade; refer to
and Sharpening the Blade (page
1. Perform the pre-maintenance procedure; refer
to Preparing the Machine for Maintenance (page
37).
2. Block the cutting unit to prevent it from falling
accidentally.
3. Examine the cutting ends of the blade carefully,
especially where the flat and curved parts of the
blade meet (Figure
1. Cutting edge
2. Sail
4. Inspect the cutting edges of all the blades.
Sharpen the cutting edges if they are dull or
nicked, sharpen only the top of the cutting edge,
and maintain the original cutting angle to ensure
sharpness (Figure
Note:
The blade remains balanced if the same
amount of metal is removed from both cutting
edges.
1. Sharpen the blade at this angle only.
5. Lay the blade on a level surface and check its
ends to ensure that the blade is straight and
parallel.
