Atco Classic 18S 3-in-1 Self-Propelled Petrol Lawnmower

From top UK brand, Atco, the Classic 18S is a versatile, three-in-one petrol rotary mower that’s capable of handling typically variable British conditions!

At the core of the Atco Classic 18S is a Stiga ST 140 engine; a top-quality, 139cc four-stroke air-cooled motor, which benefits from OHV technology – you’ll enjoy low fuel costs with reduced exhaust emissions, less fatigue inducing vibration and a cut in neighbour annoying noise. The engine is rated at a hefty 3hp, and has been equipped with a roomy 0.75-litre fuel tank for extended runtimes.

Capable of either bagging, rear-discharging or mulching clippings – with the latter mode getting the job done around 30% faster – the Atco Classic 18S 3-in-1 Self-Propelled Petrol Lawnmower can be set-up to achieve great results, whatever the grass length you’re tackling.

It boasts power-driven rear wheels, which take all the strain out of traversing slopes and rough ground, and it benefits from a generous 46cm cutting-width, which ensures a good amount of ground is covered with each and every pass.

The Atco Classic 18S 3-in-1 Self-Propelled Petrol Lawnmower’s ‘Hi-Wheel’ design not only provides scuff-free traction, but also makes it much easier to manoeuvre in overgrown grass.

A six-step height of cut – simple to set using only one lever – ensures you’ll be able to deal with variations in grass conditions through the growing season; a steel chassis provide a robust cutting platform, and contributes to Atco’s ability to offer a lengthy five-year warranty for homeowner use.

You’ll also get a ‘catcher full’ indicator, which prevents the discharge chute becoming clogged by overfilling; and a deck-wash port, which makes it easy to remove corrosive, performance inhibiting grass from the deck’s underside.

You’ll find four-stroke engine oil here.

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.
