Test the blade’s balance using a blade balancer. Grind
metal from the heavy side until it  balances evenly.

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.

angle. Always grind each cutting blade  edge equally to
maintain proper blade balance.  See Fig. 7-5.
