The STIHL 8-Tooth Grass Cutting Blade is a professional-grade steel attachment designed for high-capacity mowing in challenging conditions. Featuring eight sharpened cutting teeth, this blade provides a smoother, finer cut than 4-tooth models, making it ideal for tackling matted and dry grass, thick ferns, and reeds. It is the perfect solution for clearing resistant foliage on large properties where a standard trimmer line is insufficient.
Forged from high-quality hardened steel, this 230mm (9.1") blade is built for maximum durability and a long service life. Its reversible design allows the operator to simply flip the blade to utilize a fresh set of cutting edges, effectively doubling the time between sharpenings. With a 25.4mm (1 inch) arbor, this blade is precisely balanced to ensure smooth operation and minimal vibration across a wide range of STIHL professional powerheads.
Safety & Compatibility: This blade must be used with a brushcutter equipped with a double shoulder harness and the appropriate deflector for metal tools. For "R" (loop handle) models, a barrier bar and specialized limit stop are required for safe operation.
