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 18.
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 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 operat-

between 70 ft-lbs and 90 ft-lbs.
