FS 91 petrol brushcutter: powerful and long-lasting

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.
