What type of string do I need for my string trimmer?
Read your owner’s manual to confirm what size trimmer string (a.k.a. trimmer line) is needed for your trimmer. Some common trimmer string diameters are .065” (1.7 mm) to .155” (3.9 mm). Professional landscapers use star, cross and square-shaped string. These shapes create cutting edges that enable you to move through an area significantly faster than with round-shaped line. A cleaner cut will reduce likelihood of browned tips.
