ATIE 10" x 3T 10-inch x 3 Teeth Heavy Duty Carbon Steel Brush Cutter Trimmer Weed Eater with Washers - Blades for 20mm or 25.4mm Arbor - Compatible with Husqvarna, Stihl, Echo (2 Sets)

What It Is

This is a heavy-duty carbon steel brush cutter blade set (10-inch diameter, 3 teeth) designed for clearing thick grass, brush, and light woody vegetation. It’s intended for use with straight-shaft trimmer/brush cutter heads, not for standard lawn mower decks.

Fitment & Compatibility

• Arbor size: Works with 20mm or 25.4mm arbor holes (includes washers to adapt). Verify your trimmer’s arbor diameter before buying.
• Not a mower blade: This is for brush cutters/trimmers with a blade head, not for riding or push mower decks. Do not install on a standard lawn mower spindle.
• Brand compatibility: Fits Husqvarna, Stihl, Echo, and most brands using a straight shaft with a 20mm or 25.4mm arbor. Check your trimmer’s manual for blade compatibility.
• Installation: Requires a blade adapter or washer kit (included) to fit both arbor sizes. Ensure your trimmer head accepts a 10-inch blade (some heads limit to 8-inch).

Key Things to Know

• Quality: Carbon steel is tough but will dull faster on rocks or hard soil. Resharpen with a file or grinder.
• Installation difficulty: Easy if you have a wrench and lock nut tool. Use thread-locker on the nut to prevent loosening at high RPM.
• Common gotcha: These blades are not universal—check that your trimmer’s arbor is either 20mm or 25.4mm. Some Stihl models use 20mm, most Husqvarna use 25.4mm.
• Safety: Always use a blade guard and eye protection. Never run a blade without a properly tightened nut and washer stack.

Should You Buy It

Buy this if you need a durable, affordable replacement blade for clearing heavy brush with a straight-shaft trimmer from Husqvarna, Stihl, or Echo. It’s a solid value for two sets, but double-check your arbor size and trimmer head compatibility first—especially if your model uses a smaller 8-inch limit or a non-standard arbor.
