Grass Gator Z7105 Twisted Trimmer Line Spool, 0.105" Diameter (213 Feet) | 5 Cutting Edges | Pro-Grade Line for String Trimmers

What It Is

The Grass Gator Z7105 is a pre-wound trimmer line spool holding 213 feet of 0.105-inch diameter twisted line with five cutting edges. It’s designed for gas and electric string trimmers that use a bump-feed or fixed-line head, targeting heavy-duty trimming of thick weeds and overgrowth.

Fitment & Compatibility

Check these before buying:

• Line diameter: 0.105-inch is thicker than standard 0.080-0.095 lines. Confirm your trimmer’s head accepts this size—many lightweight trimmers do not.
• Spool type: The Z7105 is a universal replacement spool, not OEM-specific. It fits most trimmers with a standard spool chamber (e.g., Troy-Bilt, Craftsman, Ryobi, Echo, Husqvarna, Homelite, Weed Eater). Measure your existing spool’s diameter and height to ensure it matches.
• Bump-feed vs. fixed: Works with bump-feed heads; not compatible with speed-feed or Easy-Feed systems unless you swap the entire head.
• Brand/model: Not guaranteed for all trimmers. If your trimmer uses a proprietary spool (e.g., Stihl AutoCut or some Black+Decker models), the Z7105 likely won’t fit.

Key Things to Know

• 5 cutting edges means faster cutting through thick grass and brambles, but the line wears faster than round line. Expect shorter life per spool if trimming abrasive surfaces.
• Twisted design reduces line tangling and jamming compared to round line, but it can be noisier and may vibrate more on low-power trimmers.
• Installation is straightforward – it’s pre-wound, so just drop it in your head and thread the ends. No winding required.
• Common gotcha: The spool may be slightly wider than some trimmer heads. Test fit before forcing it in, or you might crack the head.

Should You Buy It

Buy this if you have a medium-to-heavy-duty trimmer (35cc+ gas or 20V+ electric) and regularly tackle thick weeds, briars, or tall grass. It’s a solid upgrade from standard round line for performance, but skip it if your trimmer uses a proprietary spool system or you only do light lawn edging.
