Otherwise, you can end up with something that’s too thick for your spindle, which can either jam it up or not fit at all. Most importantly, you should always make sure the string you purchase will fit your eater. 105 inches are suited for yards with thicker vegetation, and anything above that is designed for your extra rugged, heavy-duty projects with lots of thick brush and growth. A good rule of thumb is that lines from 0.065 to 0.080 inches are for lighter work, like typical residential lawns with light weeds. The diameter, or thickness, of the string is something else to consider. Serrated strings are the most aggressive of all, with actual cutting blades shaped into the string, to tackle heavy-duty projects.
