Rotary Mowers
Inspecting and Sharpening Rotary Mower Blades
Rotary mowers cut grass by the blade’s cutting surface
impacting against the grass stems at a high velocity. To
assure good quality of cut, the cutting edge of the blade
must be kept in a sharp condition. A dull blade will pro-
duce a ragged cut and will require an excessive amount
of engine horsepower to rotate the blade through the
grass. The most common causes for rotary mowers not
giving a good quality of cut are due to dull cutting edges
and/or bent blades.

Whenever a blade is removed for sharpening:
A. The blade must be checked to assure that it is not
bent and has the correct attitude in relation to the
housing and ground surface.

B. The blade must be sharpened correctly.
C. The blade balance must be checked each time the
blade is sharpened.
D. When installing the blade, it is very important that
the blade retaining bolt or nut be tightened to the cor-
rect torque so it will not loosen during operation.
INCORRECT – This will cause poor quality
of cut and high horsepower requirement.
WARNING
If blade is allowed to wear, a slot will form be-
tween the sail and flat part of the blade.
Eventually a piece of the sail may break off
and be thrown from under the housing, possi-
bly resulting in serious injury to yourself or a
bystander.
