Engineered for professional landscape maintenance, the STIHL FS 491 C-EM clearing saw delivers exceptional power and performance for clearing tough grass, brush, and small trees over large areas.
The STIHL FS 491 C-EM is a powerful and robust petrol clearing saw designed specifically for professional users in landscape maintenance, agriculture, and municipal services. With its potent 2.4 kW 2-MIX engine, it provides the high torque needed for large-scale clearing of tough grass, dense brush, small trees, and stubborn bushes.
This model boasts a large 520mm cutting circle and an optimised gear ratio, resulting in improved mowing performance and faster work progress. The gearbox has been technically enhanced with updates to the sealing system, main bearing, and lubricant circulation, ensuring increased robustness and a long service life even under demanding conditions. A newly designed deflector enhances visibility of the cutting attachment during operation and simplifies storage.
At the core of the FS 491 C-EM is STIHL’s M-Tronic engine management system. This intelligent technology automatically adjusts ignition timing and fuel metering to account for external conditions such as temperature, altitude, and fuel quality. This guarantees optimal engine performance and acceleration at all times without manual adjustments. The simple start logic and stop button, which automatically returns to the start position, ensure the machine is always ready for a quick restart, increasing work efficiency after breaks.
STIHL has engineered the FS 491 C-EM for prolonged use. The effective 4-point anti-vibration system dramatically reduces the oscillations from the engine, minimising the strain on the operator’s arms and hands. For added convenience, a winter setting slide control allows for quick adaptation to colder temperatures, preventing the carburettor and air filter from icing up. The long-life air filter is easily accessible and provides long service intervals, while the large, transparent 0.99-litre fuel tank allows for extended work periods with fewer refuelling stops.
Comfort during long working hours is paramount. The FS 491 C-EM features an ergonomic bike handle with the innovative ADVANCE Grip, providing a more natural working position and intuitive control. The handle can be adjusted to suit the user’s height and the specific task without the need for tools. For easy transport and storage, the bike handle can be swivelled 90 degrees. The saw is supplied complete with a BrushCut 300-3 metal blade and a comfortable ADVANCE universal harness to correctly distribute the machine’s weight.
