Blytra Weed Eater Blades Kit 6 Steel Trimmer Heads and 9 Inch 36 Teeth Brush Cutter Blade with Adapter Kit, Compatible with Trimmers and Weed Wackers

What It Is

This is a combo kit of 6 steel trimmer heads and one 9-inch, 36-tooth brush cutter blade with an adapter, designed for heavy-duty weed whacking and brush clearing on straight-shaft gas trimmers and weed wackers.

Fitment & Compatibility

• Shaft type: Only fits straight-shaft trimmers. Do not use on curved-shaft models.
• Arbor/shaft size: The brush cutter blade requires a 25.4mm (1-inch) arbor hole with a 9mm pilot hole. The adapter kit is included to fit most standard trimmer heads, but verify your trimmer’s output shaft diameter and shape (round vs. D-shaped) before buying.
• Brands: Works with most major brands (echo, Stihl, Husqvarna, Ryobi, etc.) that accept standard trimmer heads, but not compatible with universal quick-load or bump-feed heads.
• Power requirement: For the brush cutter blade, your trimmer must have at least 30cc engine displacement or equivalent electric power. Underpowered trimmers will stall or damage the gearbox.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a hex key and wrench (not included). The adapter kit requires careful alignment of the blade and locking nut.
• Blade vs. line: The 36-tooth blade cuts through thick brush, saplings, and brambles, but is dangerous on rocks, concrete, or metal—use only for vegetation.
• Trimmer heads: The 6 steel heads are heavy-duty replacements for standard plastic heads, but they add significant weight—expect more vibration and fatigue on longer jobs.
• Durability: Steel heads and blade hold up well, but the adapter’s locking mechanism can loosen over time if not torqued properly. Check tightness every 15 minutes of use.

Should You Buy It

Buy this if you need a budget-friendly, all-in-one kit for converting a straight-shaft trimmer into a brush cutter and want spare steel heads for daily trimming. Skip it if your trimmer is under 30cc, has a curved shaft, or you prefer lightweight plastic heads for ordinary grass.
