Threlaco 6 Steel Teeth Razor Trimmer Head and 3 Teeth Brush Cutter Blade Set Weed Trimmer Blades Attachments Metal Gloves for Forester(Red,9" x36t+10" x3t+6t)

What It Is

This Threlaco set includes a 9-inch, 36-tooth steel trimmer head (for heavy weeds and brush) plus a 10-inch, 3-tooth brush cutter blade and a 6-tooth blade, all with a 1-inch arbor (center hole). It’s designed for gas string trimmers and brush cutters used in clearing thick grass, brambles, and light woody growth.

Fitment & Compatibility

Before buying, verify your trimmer’s arbor size: this set uses a 1-inch (25.4 mm) center hole, which fits most straight-shaft trimmers and many curved-shaft models with a 1-inch arbor. Check your trimmer’s owner manual or measure the existing blade/head’s hole diameter. The set does not fit trimmers with a 7/8-inch or 20mm arbor (common on some Echo, Stihl, or Ryobi models). Also confirm your trimmer’s maximum blade diameter—most can handle 10-inch blades, but smaller units may require an 8-inch limit. No specific brand adapter rings are included, so universal fitment is not guaranteed.

Key Things to Know

• Quality: Steel teeth are durable for heavy brush but will dull faster than carbide-tipped blades on rocky or sandy soil. The included gloves are a basic bonus, not heavy-duty.
• Installation: Moderately easy if you have a wrench and a trimmer head lock. The blade/head uses a standard nut; ensure you tighten to manufacturer torque specs (typically 15-20 ft-lbs) to avoid loosening at high RPM.
• Common gotchas: The 36-tooth trimmer head can be aggressive—expect more vibration than a string head. Always wear eye and leg protection. The 3-tooth blade is for light brush only; avoid large branches or roots.
• Weight: Heavier than string heads, which may strain smaller trimmers (under 30cc). Check your trimmer’s recommended blade weight limit.

Should You Buy It

Buy this set if you have a straight-shaft trimmer with a 1-inch arbor and need a budget-friendly option for occasional heavy clearing, not daily professional use. Skip it if your trimmer has a non-standard arbor (7/8-inch or 20mm) or if you need carbide-tipped blades for frequent rocky terrain. The value is solid for the price, but expect moderate durability.
