Buying Guide


Using plastic lines to cut greenery and to even trim right up to rocks, stems and trees, the best rated electric string trimmer works without the weight and fumes of gas-driven and gas-and-oil models. What is the best electric string trimmer? It is best to answer that by first knowing about the essential elements that make a great product.


Pivoting Cutting Head

Whether corded or cordless, the most reliable electric string trimmer is easy to start, ensuring great weed whacking jobs with no fumes, no earsplitting noise and no mixing fuel. But models with one-step action adjustment to enable edging are perfect, thanks to a swivel cutting head. Such a feature enables you to turn the head of the string trimmer up to 90 degrees, giving you freedom to manicure sharp edges along flowerbeds, walkways, driveways and sidewalks. It can be difficult to trim edges to that neat, well-maintained, no-spots-missed appearance if the cutting head is fixed to an immobile position. The string may not be able to reach those annoyingly tall weeds on the edge, so you might have to resort to manual scissor cutting. But with a pivoting cutting head, you always do a complete job.


Line Swap

It can be annoying to have to trim a really large yard or lawn and the line runs out, needing quick replacement on the spot. Thus, some people bring an extra line in their pocket while working. But the problem is, how will you swap lines? Will the trimmer you’ve been wielding let you replace the line without a tool? If it’s a genuinely highest rated electric string trimmer, it will. With such a model, you just have to use your fingertips or snap off the trimmer head to remove the old string, and put in a fresh load of trimmer line. You will not have to make a run for the tool shed to find the perfect implement to help you do the line swapping job. It should be that easy and convenient!


Line Feed

Need more line to finish the job? When you’ve got the most reliable electric string trimmer in your hands, this should never be a problem. When the model you own is geared with Bump Feed line advance, you simply tap the head of the machine on the ground and it responds with more line released. It is normal that the line wears out and breaks off as you go along with the weed whacking work, but with bump feed, more cutting line is made available to you with a simple tap to the ground. Models with Auto-Advance line feed allow you to get more line ready for trimming via two mechanisms: through a lever or button that is pushed to advance more line; and auto-sensor technology, where the unit “detects” the need for more line and advances it automatically.


Remember to choose a unit from the top ten electric string trimmers that you believe will work best for the size of the yard, garden or lawn that you have. Buying an electric string trimmer under a budget is ideal, as long as you know exactly what you’re getting and plan to optimize your purchase as best as you can.
