10" x 3T 10-inch x 3 Teeth Steel Brush Cutter Trimmer Weed Eater Blade (1 Pack)

What It Is

A 10-inch diameter steel blade with 3 teeth designed for brush cutters and string trimmers, used to clear thick weeds, brush, and saplings instead of standard nylon line.

Fitment & Compatibility

• Mounting hole: Verify your trimmer’s arbor size (typically 20mm, 25.4mm, or 1-inch). This blade often requires a specific arbor hole—measure yours before ordering.
• Trimmer type: Fits straight-shaft gas trimmers and brush cutters with a metal blade-capable head. Not for curved-shaft or electric trimmers.
• Power requirement: Blade requires a trimmer rated for brush-cutting (at least 30cc gas engine). Lighter units may stall or lack the RPMs for safe use.
• OEM vs aftermarket: This is a universal aftermarket blade. Check your trimmer’s manual for OEM blade specs to confirm compatibility.

Key Things to Know

• Installation: Requires a dedicated blade nut and washer (often sold separately). Do not use a string trimmer head adapter—use a blade-specific arbor.
• Safety: Always wear heavy gloves and eye/leg protection. The blade can throw debris at high speed and kick back on thick stems.
• Sharpening: Teeth dull quickly on woody brush. File them with a round file (not a grinder) to avoid overheating and weakening the steel.
• Balance: After sharpening, check blade balance to prevent vibration that can damage the trimmer head and shaft.

Should You Buy It

This blade is a solid budget option for homeowners or semi-commercial users who need to clear heavy brush and weeds a few times a season. It won’t outperform premium brands but gets the job done at a low price. Best for trimmers with a metal blade guard and a straight shaft that can handle the load.
