HOW A GARDEN HEDGE TRIMMER WORKS
Electric-powered hedge trimmers are lightweight, more affordable and quieter than petrol-powered hedge trimmers. While petrol-powered hedge trimmers require fuel to operate, electric- powered hedge trimmers rely on either battery or being plugged into a power supply.
An electric-powered hedge trimmer works by using the electrical current provided by either the mains connection or the battery, to power the motor, which provides the oscillations that the blades need.
Electric motors are less powerful than petrol, but also quieter. The reduced power makes electric trimmers less effective against particularly thick branches – if you regularly need to cut through branches more than around 1/2″ thick, you’d be better off with a petrol-driven hedge trimmer.
One further advantage of electric hedge trimmers is they don’t produce any emissions at the device.
