Stihl FS 491 C-EM Petrol Strimmer / Brushcutter

Stihl FS 491 C-EM Petrol Clearing Saw

The Stihl FS 491 C-EM Petrol Clearing Saw is a powerful professional machine built for large-scale landscape maintenance and demanding clearing work. Designed for tackling tough grass, dense brush, small trees, and heavy vegetation, it delivers strong and consistent cutting performance with a 2.40 kW engine and an impressive 520 mm cutting circle diameter. The optimised gear ratio enhances mowing efficiency, allowing faster progress across wide areas while maintaining control and precision in challenging conditions.

High Power Output with Smart Engine Control

Powered by a 51.6 cm³ Stihl 2-MIX engine, the FS 491 C-EM provides high output while maintaining efficient fuel consumption. The Stihl M-Tronic system offers fully electronic engine management, automatically adjusting ignition timing and fuel metering based on external conditions such as temperature and altitude. This ensures consistent performance from start-up through to extended operation, while reducing the need for manual adjustments and improving overall reliability.

Ergonomic Design for Large Area Work

Built for extended use, this clearing saw features an ergonomic bike handle that supports a natural sweeping motion for efficient coverage of large areas. The Advance Grip handle improves control and user comfort, while the multi-function handle integrates all key controls for simple one-handed operation. Reduced vibration levels during partial load operation, supported by the Stihl 4-point anti-vibration system, help minimise fatigue and improve handling over long working periods.

Durable Build and Practical Features

The FS 491 C-EM incorporates a technically enhanced gearbox with improved sealing, bearing support, and lubricant circulation for increased durability and long service life. A large 0.99 litre fuel tank supports longer working intervals, reducing downtime for refuelling, while the transparent tank allows quick level checks. Additional features such as the stop button, simple start logic, and long-life air filter contribute to efficient operation and reduced maintenance requirements.
