The STIHL 4-Tooth Grass Cutting Blade is a high-performance steel attachment engineered for rapid mowing and thinning in challenging environments. Designed specifically for resistant foliage, this reversible blade is the ideal choice for reclaiming areas overgrown with matted and dry grass, ferns, and reeds. Its durable construction ensures a clean, controlled cut where standard nylon line fails to deliver.
Forged from high-strength hardened steel, this 230mm (9.1") blade is built for professional-grade longevity. A key operational advantage is its reversible design; when one side eventually dulls, the operator can flip the blade to access a fresh set of cutting edges, doubling the time between sharpenings. With a 20.0mm arbor, it is perfectly balanced to maintain high mowing capacity without putting undue stress on your equipment's gearbox.
Safety & Compatibility: For use with professional brushcutters equipped with a double shoulder harness and the appropriate deflector for metal tools. Approved for high-capacity models: FS 311, FS 361 C-EM, FS 461 C-EM, and the battery-powered FSA 400 series.
