Grass Gator Z7175L | Professional .175-inch | 80-Foot Twisted Trimmer line for high-Wheel and Walk-Behind Trimmers | Heavy Duty Commercial Grade Nylon copolymer String

What It Is

The Grass Gator Z7175L is a heavy-duty, .175-inch diameter twisted trimmer line designed for high-wheel and walk-behind trimmers. It’s a commercial-grade nylon copolymer string meant for clearing thick weeds, brush, and overgrown areas where standard .080 or .095 lines fail.

Fitment & Compatibility

Before buying, confirm your trimmer’s line diameter requirement—this .175-inch line is thick and only fits trimmers that accept .155–.175 inch line (check manual or existing spool). It’s optimized for high-wheel and walk-behind trimmers (e.g., DR, Swisher, Cub Cadet, Troy-Bilt) with large spools; it won’t work on handheld string trimmers. This is an aftermarket replacement—no OEM-specific part number, but it fits most standard bump-feed and fixed-head spools designed for .175 line. Measure your spool’s capacity: 80 feet of .175 line is bulky, so ensure your spool holds at least 80 feet (typically a 4–5 inch spool diameter).

Key Things to Know

• Quality & durability: The twisted shape cuts through thick grass and light brush better than round line, and the copolymer resists melting and snapping better than standard nylon. Expect longer life than budget lines.
• Installation difficulty: Moderate—the .175 line is stiff, so winding evenly on the spool takes patience. Use gloves to avoid cuts from the sharp edges. Follow your trimmer’s winding direction (usually clockwise).
• Common gotchas: This line is too thick for most handheld trimmers (e.g., Stihl, Echo) and can jam or break the head. Also, if your trimmer uses a pre-wound spool, you’ll need to rewind manually. Check if your trimmer head has a line limiter blade—some may not cut .175 cleanly.
• Performance note: Twisted line creates more noise and vibration than round line, but it’s a trade-off for aggressive cutting. Use full throttle for best results.

Should You Buy It

Buy it if you have a high-wheel or walk-behind trimmer and need to clear heavy weeds, briars, or tall grass without constantly replacing line. It’s overkill for light trimming or handheld trimmers. At $18.99, it’s a fair price for the durability and length—ideal for tough commercial or residential overgrowth.
