Clear heavy grass, weeds, and light scrub with the professional-grade STIHL 250mm Brush Knife. This high-strength steel tri-blade is engineered for durability and precision, making it the ideal choice for reclaiming overgrown fence lines and managing thick vegetation that standard trimmer line can't handle.

The STIHL 250mm Brush Knife features a reversible design, allowing you to flip the blade for a fresh cutting edge and double the time between sharpenings. Its 250mm diameter provides an efficient cutting swath while maintaining high torque, ensuring your brushcutter operates at peak performance even in dense growth.

Important Safety Note: When using this metal blade on loop-handle (R) models, a barrier bar and specialized limit stop must be installed. This blade must be used with the correct brushcutter deflector for metal tools.

Key Features & Benefits

Professional Clearing Performance

  • Tri-Bladed Steel Construction: Specifically designed to slice through thick-stalked weeds, reeds, and light brush without clogging.
  • Reversible Blade: When one side becomes dull, simply flip the blade over to utilize three brand-new cutting edges.
  • High-Impact Durability: Forged from high-quality steel to resist chipping and maintain its edge during heavy-duty landscaping tasks.

Wide Compatibility

  • Fits Gas & Battery Units: Compatible with a wide range of professional units, including the FS 91, FS 111, FS 131, and the high-torque FSA 135 and FSA 200 series.
  • KombiSystem Ready: Fits KM 91 R, KM 94 R, KM 111 R, and KM 131 R powerheads when equipped with the FS-KM trimmer attachment.
  • 25.4mm Arbor: Standard mounting size for a secure fit on most professional STIHL brushcutter gearheads.

Efficiency on the Job

  • Optimized Diameter: The 250mm (9.8") size balances cutting speed with engine load, providing the "bite" needed for thickets while protecting your equipment's gearbox.
  • Easy Maintenance: Can be quickly touched up in the field with a flat file to keep your workflow moving.
