CUTTER BLADES
Do not sharpen beyond 1/3 of the width of the blade.
(See figure 7)
-NOTE-
Dress the blade with a file. Using a wheel
grinder may burn the blade. Check the balance
of the blade. If blades are out of balance, vibra-
tion and premature wear of spindle assembly can
occur. See your authorized Scag dealer for
blade balancing or special tools, if you choose to
balance your own blades.
