Line Cut-Off Blade 638016003

This OEM line cut-off blade trims any excess or protruding string from your trimmer during operation so that it stays at an optimal length within the guard. It is in the guard assembly at the bottom of the trimmer head near the rotating spool where the trimmer line is fed. Over time, it can become dull or worn out. Look for signs of damage such as deformation, bending, or nicks. If not replaced, the trimmer may produce uneven or messy trims and put additional stress on the spool or motor, leading to premature wear or damage. To replace the blade, locate it on the grass deflector assembly and remove its mounting screws. Please note that this blade is sold individually without hardware.
