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 Spark Arrestor Muffler
Large muffler baffles help reduce noise and feature a screen designed to minimize the emission of sparks.
Protected Spark Plug
The spark plug is well-protected yet easily accessible for maintenance or replacement.
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.
