• String trimmers are landscaping devices that cut grass, especially grass that you can't reach with a lawn mower. While some trimmers are considered better than others, what makes a string trimmer a good one depends on what the owner needs. String trimmers should be comfortable to use, effectively cut grasses without any gaps and be safe. Still, some string trimmers have features that put them above the rest.
  
  

NST2018 Grass Hog

• The NST2018 Grass Hog 12-inch 18V Cordless Electric String Trimmer has a rechargeable battery, which allows landscapers to avoid tripping over or accidentally cutting the cord. This trimmer is very good at cutting short and thin grasses because of its 12-inch string, according to Consumer Unlimited. The cutting line is moved automatically through centrifugal force, which eliminates the need to shut off the trimmer and feed more string to the trimmer. The trimmer does not have a pull-string, which requires more effort to start, and is instead started using a button. A flip down edge guide allows the landscaper to have more precise trimming.
  
  

600 Grass Hog

• The 600 Grass Hog 5 A 14-inch Electric String Trimmer & Edger has a more powerful motor than most string trimmers, which allows grass to be cut much more quickly, according to Consumer Unlimited. Consumer Unlimited also points out that this trimmer has the same Automatic Feed Spool as the NST2018, which allows the landscaper to avoid bumping the trimmer against the ground. A special head designed for edging can be attached to the trimmer. The trimmer is lighter than a lot of other trimmers, which makes it more possible for those with less strength to use this trimmer.
