The STIHL FS 91 R 16.5 in. Gas String Trimmer is a commercial-grade, heavy-duty landscaping tool engineered to deliver relentless cutting performance for professionals and demanding landowners alike. Designed by STIHL , this professional walk-behind brush and grass trimmer combines extreme torque with day-long operational endurance. Powered by a fuel-efficient, high-output low-emission engine, it effortlessly tears through thick weeds, dense roadside overgrowth, and tough structural turf. Built around a rugged, solid-steel drive shaft and an ergonomic loop-handle design, this trimmer offers maximum agility in tight spaces, making it the definitive platform for sculpting clean fence lines, navigating steep ditches, and maintaining sprawling properties. Engineered to withstand the daily punishment of commercial landscaping crews, the FS 91 R features impact-resistant, lightweight polymer housings that are completely impervious to rust and corrosion. A sophisticated, built-in multi-point anti-vibration system isolates the operator from engine fatigue, ensuring exceptionally smooth handle operation during multi-hour jobs. Its high-capacity cutting head features a wide 16.5-inch cutting swath to maximize ground coverage per pass, while the specialized large-baffle muffler reduces acoustic noise and incorporates an integrated spark-arrestor screen to prevent field fires. With a simplified start procedure and a heavy-duty air filtration system that extends maintenance intervals, this commercial workhorse delivers the rugged reliability needed to conquer punishing landscaping schedules with absolute precision. Key Features: Commercial-Grade Gas Engine: Delivers massive, low-end torque with lower emissions and reduced fuel consumption to conquer thick, dense brush. Wide 16.5-Inch Cutting Footprint: Optimizes ground coverage per sweep, significantly reducing tracking time on expansive properties. Anti-Vibration Engineering: Drastically cuts down operator fatigue by absorbing mechanical engine cycles for ultra-smooth handling. Corrosion-Resistant Housings: Constructed from advanced, lightweight polymers engineered to endure heavy jobsite drops and impact. Ergonomic Loop Handle (R Configurations): Provides top-tier maneuverability and comfort when angling around obstacles, trees, and steep slopes. Large-Baffle Spark-Arrestor Muffler: Lowers environmental noise levels while containing potential exhaust sparks for safer operation near dry brush. Solid-Steel Drive Shaft: Engineered with a rigid, high-durability core to handle heavy load variations without slipping or warping. Simplified Starting Routine: Built with an intuitive, reliable starting mechanism that reduces pull resistance for hassle-free field activation. The STIHL FS 91 R Gas String Trimmer redefines landscape maintenance by bringing professional clearing power right to your fingertips, completely bypassing the runtime limitations of battery units and the stalling tendencies of entry-level trimmers. Revving up instantly with a smooth pull, it creates a perfectly balanced center of gravity that lets you sweep across dense roadside overgrowth or intricate garden borders with absolute authority. The heavy-duty engine and solid shaft alignment maintain peak rotational speed even when plunged into thick, damp weeds, preventing standard head bogging. For professional operators, land managers, and property owners wanting a rugged, straightforward, and highly agile trimming system to unlock absolute curb appeal, this robust STIHL workhorse delivers the raw cutting torque, commercial-grade durability, and localized control required to dominate any outdoor project with total confidence.
