Master Mechanic Grass Trimmer Line

These pre-cut lines are specifically designed for the Master Mechanic Pivot Head Trimmer #490-060-9019. They will not fit standard bump-feed trimmers or other brands, so please verify your model number before purchasing.

The serrated edge acts like a saw, allowing the line to grip and slice through thicker grass and light weeds rather than just whipping them. This results in a cleaner, more precise cut, especially when edging along sidewalks or garden beds.

Each pack contains nine pre-cut lengths of serrated line. This quantity is intended to last through several maintenance sessions, allowing you to swap out worn strings quickly without needing to measure or cut bulk spool line.

No, this line is designed for residential lawn care, specifically grass and light weeds. It is not intended for heavy-duty brush, woody stems, or thick vegetation, which could cause the line to snap prematurely.

No tools are required. Because these are pre-cut lengths designed for the pivot-head system, you can easily remove the old line and insert the new one by hand, making mid-task replacements very efficient.
