The STIHL 4-Tooth Grass Cutting Blade is a professional steel attachment designed for high-capacity mowing in demanding conditions. Specifically engineered to tackle matted and dry grass, ferns, and reeds, this blade provides a clean and efficient cut where standard trimmer line often struggles. Its durable construction makes it the ideal choice for reclaiming overgrown areas and managing resistant foliage on large properties.
Forged from high-quality hardened steel, this 230mm (9.1") blade is built for long-term reliability. A significant operational benefit is its reversible design; when the cutting edges eventually dull, the operator can simply flip the blade to utilize a fresh set of edges, doubling the time between sharpenings. With a 25.4mm (1 inch) arbor, it is precisely balanced to ensure smooth operation and reduced vibration across a wide range of STIHL 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.
