VIDICA 9" x 36 Teeth Carbide Tipped Blade & 10" x 3 Teeth Carbon Steel Brush Cutter Weed Eater Blades with Universal Weed Wacker Adapters, Compatible with Husqvarna, Stihl, Oregon and More

What It Is

This is a 2-in-1 blade set: a 9-inch, 36-tooth carbide-tipped mulching blade for grass, plus a 10-inch, 3-tooth carbon steel brush cutter blade for thick weeds and light brush. Designed for trimmers and brush cutters, not standard lawn mowers.

Fitment & Compatibility

• Check your trimmer head type: The set includes universal weed wacker adapters to fit most straight-shaft trimmers, but you must verify your trimmer’s shaft diameter (typically 7/8” or 1”) and drive hole pattern. Common fits include Husqvarna, Stihl, Echo, Ryobi, and Oregon.
• Deck size not applicable: These are for handheld trimmers/brush cutters, not riding or push mowers. Confirm your trimmer’s maximum blade diameter (9” for grass blade, 10” for brush blade) to avoid clearance issues.
• Aftermarket vs OEM: Aftermarket replacements for original Husqvarna/Stihl blades. May require minor adapter adjustment (some users report needing to file the center hole slightly).
• Safety check: Brush cutter blade requires a dedicated brush cutter guard and a straight shaft trimmer with a metal gearbox. Do not use on curved-shaft or low-power electric trimmers.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a wrench and the included adapters; watch a video if you’re new to blade swaps. Torque to manufacturer specs (typically 25-35 ft-lbs).
• Durability: Carbide-tipped grass blade holds an edge well; carbon steel brush blade dulls faster on thick woody material but is easy to sharpen.
• Balance: Some users report the brush blade needs balancing out of the box (use a blade balancer or file).
• Safety: Brush blade is aggressive—wear chaps, eye protection, and never use it near people or pets. The blade can throw debris up to 50 feet.

Should You Buy It

Buy this if you have a straight-shaft trimmer (Husqvarna, Stihl, or similar) and need one blade for clean lawn edges and another for clearing heavy weeds or saplings. Skip it if you only cut grass—a standard string head is simpler—or if your trimmer is curved-shaft or low-torque electric. At $20, it’s a budget-friendly two-blade starter set, but expect to balance the brush blade and possibly tweak the adapter fit.
