Brush Cutter Blade Kit for Weedeater, 9 Inch 36 Teeth Carbide Tipped and 10 Inch 3 Teeth Carbon Steel Blades, Compatible with Stihl Husqvarna Ego Oregon Hitachi Trimmer

What It Is

This kit includes two brush cutter blades: a 9-inch, 36-tooth carbide-tipped blade for heavy brush and woody material, and a 10-inch, 3-tooth carbon steel blade for grass and light weeds. It’s designed for use with straight-shaft string trimmers converted to blade cutting, commonly on Stihl, Husqvarna, Ego, Oregon, and Hitachi models.

Fitment & Compatibility

Before buying, confirm your trimmer has a straight shaft (curved shafts rarely accept blades). Check that the arbor hole size matches your trimmer’s output shaft—most use 25.4mm or 20mm, but this kit does not specify. Measure your existing blade or spindle nut diameter. Also verify the blade’s thickness (typically 0.08–0.10 inches) and that your trimmer head or adapter can accept a blade lock washer. This is an aftermarket kit, not OEM, so it may require a universal blade adapter or washer set for proper fitment on some models. Cross-reference your trimmer’s model number with the manufacturer’s recommended blade size (e.g., Stihl FS series often use 8–10 inch blades).

Key Things to Buy

• Quality variance: Carbide-tipped blade is decent for occasional brush, but 3.2-star rating suggests inconsistent sharpness and balance. Carbon steel blade may dull quickly on abrasive grasses.
• Installation difficulty: Moderate. Requires removing string head, installing blade adapter (not included), and torquing to spec (typically 20–30 ft-lbs). Use thread locker on spindle nut.
• Common gotchas: The 10-inch blade may cause vibration on trimmers rated for 8-inch max. Always wear heavy gloves and eye protection when mounting. Check blade balance before use—unbalanced blades can damage trimmer bearings.
• Not for zero-turn or push mowers: This is strictly for handheld brush cutters, not lawn mower decks.

Should You Buy It

Only if you need a budget-friendly two-blade starter set for light to medium brush clearing on a compatible straight-shaft trimmer, and you’re comfortable with aftermarket fitment adjustments. The low rating and potential balance issues make it a risky choice for heavy-duty or professional use—consider spending more on a single, well-reviewed carbide blade from Oregon or Stihl instead.
