Blade Sharpening
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° to 30° angle. See Fig. 7-2.

NOTE: It is important that each cutting blade edge be ground
equally to maintain proper blade balance. The blade can be
tested by balancing it on a round shaft screwdriver. Grind metal
from the heavy side until it balances evenly.
WARNING:
An unbalanced blade will cause
excessive vibration when rotating at high speeds. It
may cause damage to mower, and could break
causing personal injury.
