Product Description

Thanks to its STIHL 4-MIX® engine and enlarged tank, the STIHL FS 91 petrol 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 gardeners 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 petrol 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.
  • The STIHL anti-vibration system and the double-shoulder harness supplied as standard relieve the strain on your muscles and joints as you work and make long periods of use more pleasant.

STIHL 4-MIX® ENGINE:
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.

LONG AIR FILTER SERVICE LIFE:
ENSURES LONG CHANGEOVER INTERVALS. Thanks to its long service life, you rarely need to change the easily accessible filter. This saves resources and reduces maintenance effort.

MANUAL FUEL PUMP:
FOR FEWER STARTING STROKES. The manual fuel pump reduces the number of strokes required to start the 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.

BIKE HANDLE:
When used in conjunction with a harness, the bike handle enables a smooth mowing action. The bike handle allows the machine to be easily guided, making it ideal for working on large areas and thus reducing fatigue.

SINGLE-HANDED MULTI-FUNCTION HANDLE:
COMFORTABLE OPERATION. Thanks to the single-handed multi-function handle, you can control your 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.

TOOL-FREE HANDLE ADJUSTMENT:
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.

STOP BUTTON:
RESTART WORK QUICKLY. With the stop button, you can switch off your 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.
