Product information & specifications
STIHL FS 91 R Petrol Brushcutter
The STIHL FS 91 R is a powerful loop-handle petrol brushcutter designed for working in tough grass, tight spaces and hard-to-reach areas. Ideal for professional landscaping, grounds maintenance and demanding domestic use, the FS 91 R offers exceptional manoeuvrability around obstacles, trees, fencing and uneven terrain thanks to its compact loop handle and lightweight design.
Powered by STIHL’s proven 4-MIX® engine, the FS 91 R delivers strong cutting performance with reduced emissions, high torque and excellent fuel efficiency. A larger fuel tank increases working time between refills, and the rigid drive shaft ensures smooth, reliable power transfer for consistent cutting results.
Starting the FS 91 R is simple and reliable thanks to automatic decompression and the manual fuel pump which reduces the number of starting strokes required. The stop button automatically resets, allowing the engine to restart immediately after short breaks. Long-life filter design and reduced maintenance requirements make this machine a dependable workhorse for regular professional use.
Supplied as standard with a single shoulder harness and the AutoCut C 26-2 mowing head, the FS 91 R is ready for tackling dense grass and boundary trimming straight out of the box.
