One of the most powerful machines of its type currently in production, and coming equipped with a heavy-duty brush blade, the STIHL FS491 C-EM will cut effortlessly through the most challenging scrub and bramble, and will even cope with young saplings.

Its very high-performance 3.3hp (51.6cc) 2-MIX engine is controlled by STIHL’s impressive M-Tronic electronic management system, which ensures optimum performance levels are maintained under all conditions, thereby making it an invaluable feature for the professional landscaper.

STIHL’s range of 2-Mix engines are defined by their stratified charge technology, which serves to virtually eliminate fuel wastage during the combustion cycle, in turn producing a huge drop in fuel consumption and exhaust emissions.

Other key engine attributes on the STIHL FS491 C-EM include a carburettor compensator, which ensures a dirty air filter won’t overly compromise power output; and ErgoStart, which means the lightest of pulls on the starter rope is needed to get the motor going.

Operator comfort is key when designing a machine for intensive commercial use, so deservedly renowned German manufacturers, STIHL, have furnished this model with a classic ‘cowhorn’-style handlebar, four-point vibration damping and a soft, padded shoulder harness.

In addition, they’ve managed to keep machine weight down to only 9.1kg.

Shipping Info

Shipping Info

If you’re buying a boxed product, we aim to get your order delivered next working day – UK mainland where possible.

If you’re buying a tractor or ride-on mower – a special order item – it could be slightly longer, as we need to PDI the machine.

We do try and van-deliver these machines if we can, as this gives us a chance to demonstrate the product, and to ensure you’re happy and confident with your purchase.

If we can’t van-deliver your machine, as you’re out of our local delivery area, the tractor will be sent on a pallet via a courage company. They will then contact you directly to book a specific day and time that suits you.
