10" x 3 Teeth Brush Cutter Blades for Weedeater, 2-Set Carbon Steel Trimmer Blades, Arbor 1" with 7/8"-20mm-5/8 Washers

What It Is

This is a set of two 10-inch, 3-tooth brush cutter blades made from carbon steel, designed for clearing heavy weeds, brush, and saplings with a straight-shaft string trimmer or brush cutter. They replace the standard trimmer head for aggressive cutting in overgrown areas.

Fitment & Compatibility

Before buying, verify these three measurements:

• Arbor hole: Must be 1 inch exactly. Measure the center hole on your current blade or spindle.
• Washer set: Includes 7/8", 20mm, and 5/8" washers to adapt the 1" arbor to common shaft sizes—but confirm your trimmer’s shaft diameter and thread pattern (usually M10x1.25 or 5/8-11 UNC).
• Blade diameter: 10 inches. Check your trimmer’s guard clearance—some smaller units may require a 8-inch blade.
• Brand/model: Designed for Weedeater brand straight-shaft trimmers, but fits most brands (Stihl, Echo, Husqvarna, Ryobi) with a straight shaft and compatible arbor. Not for curved-shaft trimmers.

Key Things to Know

• Carbon steel vs. carbide: These are cheaper but dull faster than carbide-tipped blades. Expect to sharpen or replace more often if hitting rocks or dirt.
• Installation difficulty: Easy—remove trimmer head, install blade with supplied washers, and torque to manufacturer spec (typically 25-35 ft-lbs). Use thread locker if your trimmer vibrates heavily.
• Balance: Two-blade sets can cause vibration if not balanced. Check by spinning the blade on a nail—heavy side should be filed down slightly.
• Safety: Always use a brush blade guard and eye/leg protection. These are not for grass—they fling debris violently.

Should You Buy It

Buy this if you need a budget-friendly, disposable blade set for occasional heavy brush clearing on a straight-shaft trimmer and you’re comfortable with basic installation. Skip it if you cut daily or need maximum durability—invest in a carbide-tipped blade instead.
