A hedge trimmer, shrub trimmer, or bush trimmer[As with the term scissors, the plural terms "hedge trimmers" + c. are often used for individual trimming tools.]
Types
Stand-alone hedge trimmers
The power source of stand-alone hedge trimmers can be
human power,
gasoline, or
electricity.
-
Manual hedge trimmers (sometimes also called hedge shears or hedge clippers) are designed as large scissors or large pruning shears. They do not need anything to operate and are cheapest/most environmentally friendly.
-
Motorized hedge trimmers allow work to be done faster and with less effort than manual ones. Their cutting mechanism is similar to that of . Powered trimmers are generally designed with safety devices such that they work only when both of the operator's hands are on the handles.
-
Gasoline-powered trimmers tend to be more powerful but can be heavier and more difficult to start.
-
Electrical trimmers tend to be lighter and less powerful (than gasoline variants) as well as less polluting/noisy, yet still require an electrical cord with most types (if not equipped with rechargeable batteries).

Tractor-mounted hedge trimmers
Tractor-mounted and tractor-driven hedge trimmers also exist but are uncommon. These machines consist of a moveable arm (hydraulic boom) with a large hedge trimmer attachment at its end. Their cutting mechanism is similar to that of
mower.
Such large hedge trimmers are often confused with tractor-mounted flail mower (booms with flail mower attachments), which appear similar due to the use of booms. And in colloquial language both, tractor-mounted hedge trimmers and reach flail mowers, are imprecisely called hedge cutters, or brush cutters. In contrast to tractor-mounted hedge trimmers, reach flail mowers have a different cutting mechanism and are not only used for trimming hedges but also in several other fields of application (mowing taller grass, road verge cutting, ditch maintenance, etc.).
