To properly sharpen the cutting blade,
remove equal amounts of metal from both

angle. Always grind each cutting blade edge
equally to maintain proper blade balance.
See Figure 4-9.

Test the blade’s balance using a blade
balancer. Grind metal from the heavy side
until it balances evenly.
WARNING
A poorly balanced blade will cause excessive vibration, may
damage the rider and/or result in personal injury.
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
rider is in the operating position.
