Weed Eater Blades for 20mm or 25.4mm Arbor, 10" x 3 Teeth Carbon Steel Brush Cutter Blades for Weedeater Compatible with Husqvarna, Stihl, Oregon, and Hitachi (2 Pack)

What It Is

This is a set of two 10-inch, 3-tooth carbon steel brush cutter blades designed for heavy weed and light brush clearing. They fit trimmers and brush cutters with either a 20mm or 25.4mm arbor hole, making them a universal replacement for many commercial and homeowner-grade units.

Fitment & Compatibility

Before buying, measure your arbor hole. These blades come with both 20mm and 25.4mm center holes, but you must verify your machine’s arbor size—most Husqvarna and Stihl units use 25.4mm, while some older or compact models use 20mm. The blade diameter is 10 inches, so check your trimmer head guard clearance; many handheld brush cutters accept up to 10-inch blades, but some smaller units max out at 8 inches. These are aftermarket blades, not OEM, so they won’t have brand-specific lock holes or alignment pins—you’ll need a universal blade adapter kit if your machine requires one. Compatible with Husqvarna, Stihl, Oregon, and Hitachi models, but always cross-reference your machine’s part number.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a wrench and possibly a locking tool to hold the arbor. No special skills required, but take care to tighten to manufacturer torque specs.
• Quality: Carbon steel is durable for grass and light brush, but it will dull faster than carbide-tipped blades on heavy woody material. Expect to sharpen after a few hours of thick use.
• Common gotcha: The 3-tooth design cuts aggressively but can cause more vibration than 2-tooth or 4-tooth blades, especially on smaller trimmers. Ensure your trimmer head is balanced and the blade is centered.
• Pack size: Two blades for $21.99 is a solid value; keep one as a spare or swap when dull.

Should You Buy It

Buy this if you need a budget-friendly, universal replacement for clearing tall grass, weeds, and light brush on a standard 20mm or 25.4mm arbor trimmer. It’s a good choice for occasional homeowners or light commercial use, but skip it if you require OEM-specific fitment, carbide durability for heavy brush, or a vibration-free cut on smaller machines.
