4. 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° to 30°

separation is present, replace the blades
with new ones. See Figure 4-14.

CAUTION: If the cutting edge of the
blade has previously been sharpened,
or if any metal separation is present,
replace the blades with new ones.
WARNING! A poorly balanced blade
will cause excessive vibration, may
cause damage to thetractor and/or
result in personal injury.
5. 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 with a part
number stamped in it) facing the ground
when the mower is in the operating
position.
CAUTION: Use a torque wrench to
tighten the blade spindle hex flange
nut to between 70 ft-lbs and 90 ft-lbs.
