SCYTHING WEEDS. This is cutting by swinging
the blade in a level arc. It can quickly clear

areas of field grass and weeds. Scything
should not be used to cut large, tough weeds
or woody growths.

NOTE
Do not use a brush blade to cut trees which
exceed a diameter of 1,27 to 1,905 cm.
ANGLE TO
Scything can be done in both directions, or

just in one way which results in the debris

being thrown away from you.
That is using the side of the blade that it is

rotating away from you. Tilt down the blade
slightly on this same side .You will be hit by
some debris if you scythe in both directions.
SAWING This must be done with a saw blade
when the weeds are too thick and strong for
scything.
SCALPING
If kickback occurs, the blade may be dull,
or the material so thick and hard that you
should use a saw blade instead of the brush
blade.
Growth up to 7.62 cm in diameter, which

is too thick for scything, may be cut by
sawing. Sawing requires judgment on your
part whether to cut on the side where the EDGING
blade pulls away from you but throws back
the debris ,or on the side where the debris
is thrown away from you but the reaction is DO NOT
push which could become a sickout (blade

thrust).
TREES
Always cut on the side of the tree which will
cause the tree to fall away from the unit. A
kickout or bind may result if the tree falls
toward the unit and pinches the blade.
Do not force the blade to cut. Do not change
the angle of cut after into the wood. Avoid

using any pressure or leverage which could
cause the blade to bind or crack.
