Electric string trimmers are suitable for additional trimming in places where a normal lawn mower simply can’t reach (under trees, bushes, fences, or around the curb). Compared to petrol models, they are quieter, lighter and cheaper. On the downside, they are less powerful and your range of movement is limited by the power cord. Electric string trimmers are better suited for occasional and shorter work. For regular mowing, choose either one of the petrol models or a more powerful brushcutter (for mowing tall grass or woody undergrowth).
