Forester 2PK Chainsaw Brush Cutter Blade + File Set - 9in x 20 Teeth | Fits Most Straight Shaft Trimmers | Conversion Kit Sold Separately

What It Is

This Forester 2PK Chainsaw Brush Cutter Blade + File Set is a 9-inch, 20-tooth circular blade designed for clearing heavy brush, saplings, and overgrown weeds using a straight shaft string trimmer. It replaces the trimmer line with a chainsaw-style cutting edge for more aggressive vegetation management.

Fitment & Compatibility

Before buying, verify your trimmer has a straight shaft (curved shaft models won’t accept this blade). The blade fits most straight shaft trimmers with a standard 1-inch (25.4mm) arbor hole and a 10mm center hole for mounting. Common compatible brands include Echo, Stihl, Husqvarna, Ryobi, and Makita straight shaft models. Check your trimmer’s mounting nut size – some require a conversion kit (sold separately) for proper attachment. Measure your trimmer head’s clearance: the blade is 9 inches in diameter, so ensure your trimmer’s guard or deck has enough room to avoid contact. Always confirm your trimmer’s shaft type and mounting hardware before ordering.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to remove the trimmer head and replace it with the blade, using the included file to sharpen after use. No special tools beyond a wrench and screwdriver are required.
• Quality: The blade is made from hardened steel and holds an edge well for heavy brush, but it can dull quickly on rocky or sandy soil. The included file is basic but effective for touch-ups.
• Common gotchas: The blade is not for mowing grass – it’s for thick brush only. Using it on lawns will tear up turf. Also, the conversion kit is not included, so if your trimmer has a non-standard arbor (e.g., some Ryobi or Craftsman models), you’ll need to buy it separately.
• Safety: Always wear eye and leg protection; the blade can throw debris at high speed. Never use on a curved shaft trimmer – it can cause vibration damage or injury.

Should You Buy It

If you regularly clear heavy brush, briars, or small saplings with a straight shaft trimmer and want a durable, cost-effective blade that comes with a sharpening file, this Forester set is a solid choice. It’s not for lawn care or occasional light weeds, but for serious clearing work, it delivers reliable performance for the price.
