1. Blade bolt
5. 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
Cutting Unit Blade(s)
Both cutting edges and the sail, which is the turned-up
portion opposite of the cutting edge, contribute to a
good quality of cut.
Maintain sharp blades throughout the cutting season.
Sharp blades create a clean cut without tearing or
shredding the grass blades.
Check the blades for any wear or damage. The sail
lifts the grass up straight, thereby producing an even
cut and gradually wears down during operation.
1. Park the machine on a level surface, raise the
cutting unit to the T
the parking brake, shut off the engine, and
remove the key.
2. Raise the cutting unit to the S
refer to your traction unit Operator's Manual.
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 mower. If you notice wear
(Figure 26), replace the blade.

and sharpen the cutting edges if they are dull

Sharpen only the top of the cutting
edge and maintain the original cutting angle
to ensure sharpness
remains balanced if the same amount of metal
is removed from both cutting edges.
