A hedge trimmer, shrub trimmer, or bush trimmer is a gardening tool or machine used for trimming (cutting, pruning) hedges or solitary shrubs (bushes). Different designs along with manual and powered versions of hedge trimmers exist.
Stand-alone hedge trimmers
The power way to obtain stand-alone hedge trimmers could be human power, gasoline, or electricity.
Manual hedge trimmers (sometimes also known as hedge shears or hedge clippers) were created as large scissors or large pruning shears. They don’t need anything to use and are cheapest/most green.
Motorized hedge trimmers allow work to be achieved faster and with less effort than manual ones. Their cutting mechanism is comparable to that of finger-bar mowers. Powered trimmers are usually made with safety devices in a way that they work only once both of the operator’s hands are on the handles.
Gasoline-powered trimmers tend to be powerful but could be heavier and more challenging to start.
Electrical trimmers have a tendency to be lighter and less powerful (than gasoline variants) in addition to less polluting/noisy, but still require a power cord with most types (if not built with rechargeable batteries).
