0.155-In x 109-Feet Xtreme Professional Grade Trimmer Line for MTD, Swisher, Poulan, Ariens, Troy-Bilt, Craftsman

What It Is

This is a 0.155-inch diameter, 109-foot spool of professional-grade trimmer line designed for gas string trimmers. It’s built for heavy-duty cutting of thick grass, weeds, and light brush, and is compatible with several major brands including MTD, Swisher, Poulan, Ariens, Troy-Bilt, and Craftsman.

Fitment & Compatibility

Before buying, confirm these three things:

• Line diameter: 0.155-inch is thicker than standard residential lines (usually 0.080–0.095). It only fits trimmers designed for 0.155-inch or larger line. Check your owner’s manual or the line size printed on the trimmer head.
• Trimmer head type: This spool works with bump-feed or fixed-line heads that accept pre-wound spools. It will not fit manual-feed or universal replacement spools unless the spool shape matches your model.
• Brand/model check: While listed for MTD, Swisher, Poulan, Ariens, Troy-Bilt, and Craftsman, compatibility varies by specific model. Measure your existing spool’s width and center hole diameter to ensure a match. This is an aftermarket part, not OEM.

Key Things to Know

• Durability: Professional-grade line lasts 2–3x longer than standard line, especially on abrasive surfaces like concrete or gravel.
• Installation: Easy to swap if your trimmer uses pre-wound spools. For fixed-line heads, you’ll need to cut and thread individual pieces from the spool.
• Common gotcha: This line is thicker than standard, so it may cause harder starting or engine bogging on smaller trimmers (under 25cc). It’s best for mid-to-large trimmers (30cc+).
• Spool reuse: The spool itself is single-use; you cannot rewind it with new line. Plan to buy a new spool when empty.

Should You Buy It

Buy this if you have a gas trimmer from MTD, Swisher, Poulan, Ariens, Troy-Bilt, or Craftsman that accepts 0.155-inch line, and you need a tough, long-lasting line for heavy weed duty. Skip it if you have a small electric or low-cc gas trimmer, or if you prefer to rewind your own spools—you’ll waste the spool each time.
