Your Yardworks grass trimmer is an invaluable yard grooming tool. As with any other machine with moving parts, normal wear and tear is expected over time. The trimming string will eventually wear down and break off. Replacement of this vital component is quick and easy thanks to the option of buying a pre-wound spool of trimmer string. The string is available online or in most standard hardware retailers. A Yardworks spool comes standard with 0.080 diameter string.
