ARNOLD WLS-65 Trimmer Line, 0.065 in Dia, 40 ft L, Nylon

Your trimmer line should be replaced every season. Old line can be weak and easy to break. It can also wear down from cutting thick weeds or against hard surfaces causing you to not be able to cut as well. With Arnold Residential Line you can cut up to 3 times more area than economy lines depending on cutting conditions and type of trimmer head.
