An entry-level strimmer, the powerful but lightweight STIHL FS40, is the perfect tool for post-mowing tidying, fence-line maintenance and lawn edging.

Driving it is a high-performance 27.2cc two-stroke power unit, which is equipped with a capacious 0.34-litre fuel tank for a reduction in the frequency of time-consuming refuelling stops.

The engine is rated at a beefy 1hp, features an electronic ignition for consistently reliable starting and utilises STIHL’s fuel saving and emission cutting stratified-charge technology.

The German-designed STIHL FS40 Grass Trimmer comes with a nylon-line head, which incorporates a ‘Tap & Go’ mechanism – there’s no need to attend directly to the cutter head when the cord has become worn. For heavier-duty applications, a three bladed PolyCut brushcutting head can be fitted.

This easy handling model is impressively lightweight (only 4.4kg) and features STIHL’s usual high-specification ergonomics; a combination that means it couldn’t be more comfortable to work with.

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.
