Brush Cutter Blade Adapter kit, 2 Different Models 1 Wrench Sets, Trimmer Attachments for Most String Trimmers Brush Cutter

What It Is

This brush cutter blade adapter kit converts a standard string trimmer into a brush cutter by attaching metal or plastic blades. It includes two different adapter models and a wrench set, designed for clearing heavy weeds, brush, and small saplings.

Fitment & Compatibility

Before buying, check these three things:

• Drive shaft size: Most string trimmers use a 25.4mm (1") or 26mm output shaft. Measure your trimmer’s shaft diameter at the head. The kit fits common sizes but not all—verify against your model.
• Arbor hole pattern: The adapter must match the blade’s center hole (typically 20mm or 25.4mm round, or a star/pentagon shape). If you already have blades, measure their arbor hole. If not, the kit usually works with standard universal blades sold separately.
• Trimmer type: Straight-shaft trimmers are generally compatible; curved-shaft models often lack the torque or mounting depth for brush cutters. Check your owner’s manual or measure the shaft end.

No OEM-specific fit—this is a universal aftermarket kit. It will not fit all trimmers; compatibility is limited to models with a removable head and enough clearance for a blade.

Key Things to Know

• Installation is moderate: Requires removing the trimmer head, installing the adapter, and tightening a lock nut. The included wrench helps, but you may need a vice or extra leverage.
• Quality is budget-tier: At $9.59, expect basic steel adapters with potential for rust or wobble over time. Not for heavy commercial use.
• Safety gear required: Brush cutter blades throw debris at high speed. Always use a shoulder strap, eye protection, and chaps. Never use a standard trimmer head guard—get a dedicated brush cutter guard.
• Blades not included: The kit is adapters and wrench only. You’ll need to buy compatible brush blades separately (e.g., 3-tooth or 4-tooth steel blades).

Should You Buy It

Buy this if you have a compatible straight-shaft trimmer and want a cheap way to clear thick brush occasionally, without investing in a dedicated brush cutter. Skip it if you need a durable, daily-use solution or have a curved-shaft trimmer—you’ll likely strip the adapter or damage the unit.
