3.
Secure the blade from turning
clockwise when reinstalling the flange
lock nut (the opposite direction of
blade removal).
4.
Install the flange lock nut onto the
spindle shaft over the blade and flat
washer. Torque to 100-130 ft-lbs (136-
176 N-m).
WARNING
Never mow with dull blades. Blades that are bent should
be replaced. The cutting blades are sharp and can cause
severe injury. Wrap the cutting surface of the blade with
a rag and wear heavy gloves to avoid injury.
Sharpening the Blades
1.
Set the parking brake.
2.
Clean any debris from the blades. Keep
blades sharp and free of build up at
all times.
3.
To properly sharpen the cutting blades,
remove equal amounts of metal from
both ends of the blades along the
cutting edges, parallel to the trailing
edge, at a 25°-30° angle. Always grind
each cutting blade edge equally to
maintain proper blade balance. See
Figure 4-28.
Figure 4-28
WARNING
If a blade is bent or otherwise damaged, replace
the blade with a new one. Use only original
equipment blades.
WARNING
A poorly balanced blade will cause excessive
vibration, may damage the machine, and/or result in
personal injury.
4.
Test the blade's balance using a blade
balancer. Grind metal from the heavy
side until it balances evenly.
NOTE: When replacing the blade, be
sure to install the blade with the side of
the blade marked ''Bottom'' or "Grass
Side" (or with a part number stamped
in it) facing the ground when the
mower is in the operating position.
WARNING
Use a torque wrench to tighten the blade spindle hex
flange nut to between 100 ft-lbs and 130 ft-lbs.
