SHARPENING THE BLADE (See Fig. 20)
For best mowing performance, the mower blade must be kept sharp. A dull blade does not cut
grass evenly and overloads the motor. Under normal circumstances, sharpening the blade twice
during the mowing season is usually sufficient. However, if your lawn has sandy soil, more
frequent sharpenings may be required.

DO NOT attempt to sharpen the blade while it is attached to the mower.

removing equal amounts of material from both ends.
BALANCING THE BLADE (See Fig. 21)
When sharpening, care should be taken to keep the blade balanced. An unbalanced blade will cause
excessive vibration when the mower is running. This vibration will eventually cause damage to the
mower, especially the motor.
To check the blade balance:

downward, sharpen the heavy side until the blade is balanced.
When removing, inspect the blade carefully. If blade is bent or damaged, replace immediately
with a new blade. Failure to replace a bent or damaged blade could cause an accident resulting
in possible serious injury.
