Hedge Trimmers
Electrical Trimmers
Plug-in trimmers account for the most sales, since they're relatively light, quiet, and inexpensive, start with push-button ease, produce no exhaust emissions, and require little maintenance. The best also perform comparably to petrol-powered models. But you'll have to work within range of a power outlet and be careful not to cut the cord.
Petrol Trimmers
Landscapers favour these for their power and mobility. But petrol models typically weigh more than electrics, and their two-stroke engines require fuel mixing, pull-starting, maintenance. They are usually more expensive.
