FourShow 9Pcs Brush Cutter Replacement Blades Compatible with Weed Warrior Brush Cutter Head

What It Is

A set of 9 replacement brush cutter blades designed for string trimmer heads that accept universal or Weed Warrior-style blade attachments. These are for heavy-duty clearing of thick weeds, brambles, and light brush, not for standard grass trimming.

Fitment & Compatibility

Before buying, confirm your trimmer head is a Weed Warrior or a universal blade-compatible head (often with a central bolt and slotted blade retention). These blades have a 0.125-inch (3.2mm) thickness and a 2.75-inch (70mm) outer diameter with a 0.375-inch (9.5mm) center hole. They will not fit standard string trimmer spools or heads without a blade adapter. Measure your existing blade’s hole diameter and thickness—if they match, they’ll likely work. Not for use on walk-behind mowers or brush cutters with fixed metal blades.

Key Things to Know

• Material: Made from hardened steel, but may dull faster on rocky or abrasive soil compared to OEM or premium carbide-tipped blades.
• Installation: Simple—remove the nut, swap blades, and tighten securely. Always disconnect the spark plug or battery before working.
• Safety: These blades throw debris at high speed. Wear heavy-duty gloves, eye protection, and long pants. Never use with a standard string trimmer guard—use a brush cutter guard.
• Common gotcha: The 9-blade pack includes 3 sets of 3 blades; rotate or replace as a set to maintain balance and avoid vibration.

Should You Buy It

A solid budget pick if you need a quick, disposable blade set for occasional heavy brush clearing and your trimmer head accepts universal blades. Not ideal for daily professional use or abrasive conditions—expect shorter lifespan than premium brands, but at this price, it’s a good value for homeowners.
