CUTTER BLADES
Do not sharpen beyond 1/3 of the width of the blade. (See figure 7)
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.
