Master Mechanic 490-010-9023 40' .080" Star Shaped Trimmer LINE, Natural

What It Is

This is a 40-foot spool of 0.080-inch star-shaped trimmer line, designed for gas, electric, and battery-powered string trimmers. The star shape cuts more aggressively than round line, making it suitable for clearing thick grass and light weeds.

Fitment & Compatibility

Before buying, check your trimmer’s line diameter specifications—this 0.080" line fits most standard residential trimmers that accept 0.065" to 0.095" line. Confirm your trimmer’s spool capacity: 40 feet is a standard length for mid-sized spools. This is an aftermarket line, not OEM Master Mechanic branded, but it’s compatible with any trimmer that uses bump-feed or fixed-line heads. Measure your existing line diameter with a caliper if unsure; using too-thick line can damage the trimmer head or motor.

Key Things to Know

• Quality: Star-shaped line cuts faster than round line but wears quicker—expect slightly shorter life on abrasive surfaces like concrete or gravel.
• Installation: Easy to load; follow your trimmer’s manual for winding direction. The star shape may require a bit more finesse to thread through the head’s eyelets.
• Gotcha: This line is natural/green color—no added dye, so it blends in with grass. Mark your spool with tape to avoid losing it in the yard.

Should You Buy It

Buy this if you need a budget-friendly, aggressive-cutting line for regular grass and weed trimming on a standard residential trimmer. Skip it if you trim near hard surfaces frequently—you’ll get better durability from a thicker or round line.
