EFFORTLESS MOWING OF LARGE AREAS. The ergonomic bike handle helps you mow large areas quickly and effortlessly, as this handle supports a natural brushcutter movement. The bike handle is easy to adjust and secure.

FOR FANTASTIC ENGINE POWER WITH LOW MAINTENANCE. The STIHL 4-MIX® engine is a four-stroke engine that does not require any oil circuit components, thanks to refuelling with an oil and gasoline mix. That’s why it’s more compact, more lightweight, and requires less maintenance than conventional four-stroke engines, while at the same time being powerful and offering a comfortable sound pattern. STIHL 4-MIX® engines comply with the European Stage V emissions directive.

RESTART WORK QUICKLY. With the stop button, you can switch off your power tool quickly and easily for a short break, for example. As the button springs back to its original position after actuation, the engine is immediately ready to start again. This provides more comfort after breaks and increases your work efficiency.
Simplified starting system
SET THE BIKE HANDLE POSITION. You can individually adjust the ergonomic bike handle (mowing handle) using the central clamping device. Thanks to the tool-free handle adjustment, you do not need any tools for this. The bike handle can be rotated 90 degrees for transport and space-saving storage.

FOR FEWER STARTING STROKES. The manual fuel pump reduces the number of strokes required to start the power tool, making the start-up process quicker and easier This is particularly helpful after longer breaks in operation. To use it, actuate the pump several times before starting. This will ensure that there is enough petrol in the carburettor when starting.

COMFORTABLE OPERATION. Thanks to the single-handed multi-function handle, you can control your power tool easily and reliably with one hand. Because all relevant control elements are integrated in the handle, it can be operated by both right-handed and left-handed users.

FOR MORE PLEASANT WORK. Vibrations can occur when you put your power tools through their paces, and these are particularly noticeable in the grip area. The buffer and spring elements of the STIHL anti-vibration system reduce the transmission of engine vibrations to the handle area and therefore to your body. The result is that your power tool is more comfortable to hold and your work is much less tiring.

FS 91 gas brushcutter: powerful and long-lasting

Thanks to its STIHL 4-MIX® engine and enlarged tank, the STIHL FS 91 gas brushcutter is ideal for mowing large green areas. Thanks to the large selection of different cutting tools available, the tool can remove both tough grass and weeds with ease. This brushcutter is particularly suitable for yarders and landscapers, municipalities, and fruit growers with larger orchards, because the reduced-emissions engine with its rigid drive shaft offers very high engine power and high torque. Other practical advantages of the STIHL FS 91 gas brushcutter include:

  • the ergonomic bike handle can be adjusted without using tools and its shape supports a natural scything motion.
  • The one-hand multi-function handle and stop button make operation easier and more efficient.
  • The air filter has a long service life and is easy to replace; long maintenance intervals mean you can work without interruption for longer.
