Description:

If you’re a landscaping professional who uses a trimmer for mowing applications, grab the powerful STIHL® FS 91 trimmer. Its bike-handle design provides greater comfort and leverage, thanks to redesigned rubberized grips. The trimmer also features one-touch stop and a simplified starting procedure enabled by the semi-automatic choke lever. Its low exhaust emission engine is paired with a larger fuel tank, delivering 30% longer run times compared to the previous model. The engine also features improved air filtration and STIHL-exclusive IntelliCarb™ technology for maintaining maximum RPM, even as the air filter begins to clog. When the terrain gets tough, the FS 91’s solid steel drive shaft accepts a wide range of heavy-duty cutting heads, including metal blades, for maximum versatility.

Features:

• Straps and Harnesses
• Designed to distribute weight from your hands to your shoulders, straps and harnesses help reduce operator fatigue, making it easier to use trimmers, brushcutters, and clearing saws for extended periods.
• TapAction™ AUTOCUT® Cutting Head
• TapAction™ technology allows users to easily adjust line length simply by tapping the cutting head against the ground.
• Bike Handle
• When used with a harness, the bike handle enables smooth horizontal mowing over large areas quickly and efficiently. Soft, rubberized grips offer increased comfort and greater control, helping to reduce operator fatigue.
• Anti-Vibration System
• STIHL’s anti-vibration system minimizes vibration levels, helping reduce operator fatigue and providing a more comfortable working experience.
• Shoulder Strap / Carrying System
• A shoulder strap or carrying system distributes the equipment's weight for improved operator comfort and greater maneuverability during extended use.
• Multi-Function Control Handle
• All major controls are conveniently located on one comfortable handle, allowing the operator to complete tasks easily without taking their hand off the handle.
• Simplified Starting Procedure
• Starting is simple: pump the fuel primer, set the choke, and pull the starter cord. The built-in stop switch shuts the engine off with a single button press and automatically resets the throttle lock to the "start" setting for easy restarting.
• Air Filter Cover
• Quickly and easily remove the air filter cover for fast cleaning or replacement.
• Protected or Enclosed Control Cables
• Control cables are securely enclosed to eliminate dangling wires, increasing durability and reliability.

• Protected Choke Lever/Knob
• The choke is shielded to help prevent damage during operation and transport.
• High-Tech Polymer Housing
• Durable, lightweight housings withstand greater impact and resist corrosion for longer service life.
• Heavy-Duty Steel-On-Steel Clutch
• This centrifugal clutch design minimizes slippage for improved efficiency and longevity.
• Purge Pump Primer
• By pressing the primer bulb, fuel is delivered directly to the carburetor, reducing the number of starting pulls required after extended storage.
• Upright Translucent Fuel Tank
• Easily monitor fuel levels at a glance and refill with ease thanks to the upright, translucent tank design.
• Fully-Lined Drive Shaft
• The lined shaft ensures smoother operation and reduces vibration during use.
• Throttle Trigger Interlock
• For added safety, the throttle trigger can only be activated when the interlock is depressed.
