Frequently Asked Questions (FAQs)
1. How long does a spool of string trimmer last?
It lasted about 2 months, but that was heavy use. If you are doing large weeks, hit a lot of fences, of course it will last less time. I would think with a small city yard, it would last a whole summer.
2. What are the sizes of string trimmer line?
String trimmer line comes in a range of thicknesses. For light work, such as trimming grass, 0.065″-0.085″ should be sufficient. For thicker grass and weeds, a line in the 0.085″-0.110″ range will get the job done, and for thicker underbrush, anything thicker than 0.110″ will work.
