blades made by other manufacturers, because they
could be dangerous.
1. Perform the pre-maintenance procedure; refer
to Preparing the Machine for Maintenance (page
36).
2. Block the cutting deck to prevent it from falling
accidentally.
3. Grasp the end of the blade using a rag or
thickly padded glove and remove the blade bolt,
anti-scalp cup, and blade from the spindle shaft
(Figure 72).
1. Blade bolt
4. Install the blade with the sail facing toward the
cutting deck, with the anti-scalp cup and blade
bolt (Figure 72).
5. Tighten blade bolt to 115 to 149 N∙m (85 to 110
ft-lb).
Inspecting and Sharpening the
Blade
1. Perform the pre-maintenance procedure; refer
to Preparing the Machine for Maintenance (page
36).
2. Block the cutting deck 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
Note:
Because sand and abrasive material
can wear away the metal that connects the flat
and curved parts of the blade, check the blade
before using the machine. If you notice wear,
replace the blade; refer to
(page 55).

Removing the Blade
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
Note:
The blade remains balanced if the same
amount of metal is removed from both cutting
edges.

1. Sharpen at this angle only.
5. To check the blade for being straight and
parallel, lay the blade on a level surface and
check its ends.
Note:
The ends of the blade must be slightly
lower than the center, and the cutting edge must
be lower than the heel of the blade. This blade
produces a good quality of cut and requires
minimal power from the engine. By contrast,
replace a blade that is higher at the ends than
the center or the cutting edge is higher than the
heel, because the blade is bent or warped.
6. Install the blade with the sail facing toward the
cutting deck, with the anti-scalp cup and blade
bolt.
7. Tighten the blade bolt to 115 to 149 N∙m (85
to110 ft-lb).
