They are indeed the most practical choice if you have a current plug available. They are maintenance-free, lighter and handier, suitable for medium-sized works.Electric hedge trimmers are clearly less powerful than petrol ones but they are silent and have an excellent value for money. They are perfect if your garden is not too wide, but they are not suitable to work on very large surfaces. You can use an extension cord to reach the farthest points. Their theeth are narrower, for maximum 15 mm cuts and shorter bars, proportionate to the lower power and the lighter structure.
Battery-powered hedge trimmers are undoubtedly the most practical and handiest. In fact, they are lighter than the petrol ones and more functional than the electric ones. They do not need the power supply cable, so you can use it in any point of your garden without an electric plug nearby. However, their limit is the running time that depends on the battery.

They are generally divided into two subcategories: 2-stroke ones e q4-stroke ones. The 2-stroke hedge trimmer is more powerful but it consumes more fuel, while the 4-stroke consumes less and it is more silent. The distance between the teeth is the widest available, for cuts up to 20 mm. Their blades and gears are more robust compared to electric hedge trimmers, but you cannot use them on dry or old branches, which have to be cut with scissors or chainsaw: their hardness would damage the blades and gears, because their structure is more suitable for fast works than hard works.
Within the previous three categories, we can add a fourth, which is not characterized by engine type nor noisiness, but by the presence of a fixed or telescopic extension pole. This particular product category allows you to reach higher hedges or branches without using inconvenient ladders. In addition, it is almost always possible to adjust the head where the blade is mounted, so the cuts are more accurate.They are divided in:
