To properly sharpen the cutting blades, remove equal
4.
amounts of metal from both ends of the blades along the
cutting edges, parallel to the trailing edge, at a 25°- to 30°
angle. Always grind each cutting blade edge equally to
maintain proper blade balance. See Fig. 7-8.
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 the
tractor and/or result in personal injury.
Test the blade’s balance using a blade balancer. Grind
5.
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.
