Scything weeds
This is cutting by swinging the cutting attachment 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.
If a sapling or shrub binds the cutting attachment, do not use the cutting attachment as a lever
to free the bind, because this will cause cutting attachment failure.
Instead, shut off the engine and push the sapling or shrub to free the blades.
Do not use a cracked or damaged blade.
