• A weed trimmer uses fast-moving string or blades to trim grass and weeds in tight spots where a lawnmower cannot reach. Weed trimmers are usually carried by the user and vary in quality. A few models have consistently high scores when reviewed and are considered by experts at Popular Mechanics and elsewhere to be the best choices available.
  
  

Husqvarna 125L

• The experts at Popular Mechanics recommend this weed trimmer above all others in the commercial, heavy-duty category. This model features a much more powerful engine, a stronger shaft and is easy to start. The head of this trimmer is also designed to prevent weeds from tangling up and stopping the spinning, which is a problem that plagues many other string trimmers. The only downside to this model is its higher cost. If you have a large property to upkeep, or can use the trimmer for commercial work, the cost will be offset by the longer life and higher power of this model.
  
  

Black & Decker Grass Hog NST2018

• If you have a generally well kept lawn and need a lightweight, cordless electrical trimmer to take care of occasional long grass and weeds, the Black & Decker Grass Hog NST2018 comes highly recommended. The ConsumerSearch website lists it as one of the most consistently high ranked cordless electric trimmers, but it is only appropriate for light use. Its short battery life is balanced out by a lightweight and easy-to-maneuver design that won't strain your back. If the weeds in your yard have tangled the line of other string trimmers, this model may not work for you as it is prone to tangling when used on tall or heavy plant matter.
  
  

Echo SRM 210i

• This gas powered weed trimmer packs extra power into a lightweight, curved shaft design for less strain on the user. The Galt Home Buying Guides ranks it as the second best gas powered trimmer due to its higher price, but it offers a wider variety of helpful features than the number one model. The head features a debris shield to prevent damage, and it has a special system designed to eliminate the difficult starting process most gas powered weed trimmers have. This model is a good choice for homeowners who need a lightweight model without sacrificing power but a heavier and more powerful commercial weed trimmer can be found for the same price.
