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.
