0.155 Inch x 68FT Twisted String Trimmer Line, Heavy Duty Replacement Trimmer Line Compatible for Earth-Quake, Senix, Toro 58620, Built, Universal Walk Behind String Trimmers

What It Is

This is a 0.155-inch diameter, 68-foot twisted string trimmer line designed for heavy-duty trimming in walk-behind string trimmers. It’s a universal replacement line compatible with Earth-Quake, Senix, Toro 58620, Built, and similar models, intended for clearing thick grass and light brush.

Fitment & Compatibility

Before buying, check these specifics:

• Line diameter: 0.155-inch is thicker than standard 0.080-0.105 lines. Confirm your trimmer’s spool or head accepts this size (check manual or spool label). If too thick, it won’t feed or may damage the head.
• Trimmer type: Designed for walk-behind trimmers, not handheld or backpack models. Verify your model is listed (Earth-Quake, Senix, Toro 58620, Built) or has a compatible spool.
• OEM vs aftermarket: This is aftermarket, not Toro OEM. It should fit Toro 58620, but check spool compatibility for other brands—some require specific loading patterns.
• Length: 68 feet is enough for 1-2 refills on most walk-behind trimmers. Measure your spool capacity; overspooling can cause jams.

Key Things to Know

• Durability: Twisted design increases cutting strength for heavy weeds and brush, but it’s stiffer than round line—may wear spool bushings faster on older trimmers.
• Installation: Easy to load if your spool has a hole or slot. Follow the “twist-and-feed” method to avoid tangling. No tools needed.
• Gotcha: 0.155-inch line can cause overloading on low-power (electric) walk-behind trimmers. Only use on gas models with at least 4-5 HP for best performance.
• No reviews yet: Only 1 rating at 5.0 stars—limited feedback. Buy with confidence if fitment checks out, but test on a small patch first.

Should You Buy It

Buy this if you own a gas-powered walk-behind trimmer from Earth-Quake, Senix, Toro 58620, or Built, and need heavy-duty line for thick grass or light brush. Skip it for electric trimmers or if your spool requires thinner line (under 0.130-inch). At $13.77 for 68 feet, it’s a solid value for tough jobs.
