Additional Information
The MTD Line Trimmer Cutting Head Assembly (part number 841-013303S) connects to the trimmer?s drive shaft and holds the cutting line in place. It?s built to maintain consistent rotation and cutting performance across a range of grass and light brush conditions.
If your trimmer is cutting unevenly or the line frequently breaks, the cutting head may be worn or cracked. Replacing the entire assembly helps restore proper balance and function for more efficient trimming.
Before installing, disconnect the trimmer from its power source and wear work gloves for protection. Use a screwdriver to remove the old assembly and follow the parts diagram in your model?s manual to attach the new head securely. Confirm the cutting line feeds correctly and rotates freely before resuming operation.
Routine inspection of the cutting head helps prevent trimming issues and supports safe, reliable yard maintenance.
