Description
Why buy the STIHL FS 91 R 17″ Brushcutter?
- Powerful and efficient high-torque STIHL 4-MIX® engine
- Loop handle for excellent control and manoeuvrability in tight spaces
- Simplified starting system with manual fuel pump and automatic decompression
- STIHL anti-vibration system significantly reduces operator fatigue during long use
- Supplied with AutoCut C 26-2 mowing head and a single shoulder harness
- Ideal for landscape maintenance and clearing large areas of tough, long grass
The STIHL FS 91 R is a powerful petrol brushcutter specifically engineered for working in areas with tough grass, especially those that are difficult to access or have tight spaces around obstacles. It is an excellent choice for landscape maintenance professionals and property owners with challenging terrain.
It is powered by STIHL’s innovative 4-MIX® engine, which combines the benefits of 2-stroke and 4-stroke technology. This results in high torque, lower emissions, and a more pleasant sound, all while running on the same fuel mix as a standard 2-stroke engine. The engine is complemented by a larger fuel tank, extending cutting time between refills.
Powerful & Easy to Start 4-MIX® Engine
The STIHL 4-MIX® engine delivers fantastic power with reduced maintenance needs. As a four-stroke engine that runs on a petrol-oil mix, it eliminates the need for separate oil circuit components, making it more compact and lightweight than conventional four-stroke engines. The automatic decompression system makes starting effortless by reducing the compression pressure during the pull-start, significantly lessening the force required on the starter cord. A manual fuel pump further simplifies the starting process, especially after long breaks, by ensuring the carburettor is primed with fuel.
Designed for Operator Comfort and Control
Working for extended periods is made more comfortable thanks to the STIHL anti-vibration system. Buffer and spring elements within the machine reduce the transmission of engine vibrations to the handle area, protecting the operator’s arms and hands from fatigue. The loop handle design is perfect for navigating tight spaces, such as thinning between bushes and shrubs, providing precise control. The FS 91 R is supplied with a single shoulder harness to help support the machine’s weight during use.
Smart Features for Efficient Work
The FS 91 R is packed with features for efficiency. The convenient stop button allows the user to switch off the engine for a short break and, as it springs back into the ‘on’ position, the machine is immediately ready to restart. The easily accessible air filter has a long service life, reducing maintenance effort and saving resources. The machine is supplied as standard with the AutoCut C 26-2 mowing head and features a rigid drive shaft for durable power transmission.

Frequently Asked Questions
Who is the STIHL FS 91 R brushcutter suitable for?
The STIHL FS 91 R is ideal for professional landscapers and homeowners with large or challenging properties. Its robust build, powerful 4-MIX® engine, and loop handle make it perfectly suited for clearing tough grass, weeds, and undergrowth in areas that are hard to reach or have many obstacles.
What is a STIHL 4-MIX® engine?
The STIHL 4-MIX® engine is a unique four-stroke engine that runs on a petrol-oil mixture, just like a two-stroke. This innovative design combines the advantages of both engine types, offering higher torque, lower emissions, and a more pleasant sound than a typical 2-stroke, while being lighter and less complex than a conventional 4-stroke engine.
What is included with the STIHL FS 91 R?
The STIHL FS 91 R is supplied with the AutoCut C 26-2 mowing head, which is designed for easy line refilling and tapping on the ground to advance the line. It also includes a single shoulder harness to help distribute the machine’s weight and improve comfort during operation.
How does the anti-vibration system help?
The STIHL anti-vibration system uses buffer and spring elements to dampen the oscillations from the engine. This significantly reduces the vibrations felt by the operator through the handles, leading to less fatigue in the hands and arms. It allows for more comfortable work over longer periods and can help prevent long-term health issues associated with high-vibration tools.
