Atco Classic 20S – Self Propelled Petrol Lawnmower

  • Product Details

    Powered by a Stiga ST170 – 166cc Auto-choke engine, this ensures quick and easy starting, low fuel costs and reduces emissions. The ergonomic handlebars adjust into one of two settings to suit your ideal mowing position and can also be folded forward for easier storage. The centralised cutting height adjustment means you can easily adjust the height of cut to 6 positions ranging from 22-80mm for the perfect cut every time.

    The robust 51cm cutting deck with anti-scalp plate is designed to minimise scalping and improve the cut. Included as standard, the mulch plug can be fitted to return the extra fine clippings back into the lawn to fertilise and add valuable nutrients.

    The 60 litre grass collector also features an indicator to show when the bag is full. Easy to remove for emptying and collapsible for storage.

    About Atco

    In 1921 the first 900 petrol-powered Atco lawnmowers rolled off the production line at the Atco mowers factory in Birmingham and were delivered, believe it or not, by a man on a motorcycle with a specially developed side-car for transportation of these heavy machines. Things have moved on a little since then for Atco mowers, but one thing remains the same — the quality of the Atco mowers and products is as good as it ever was, and even though they expanded into different areas of the garden machinery market, it is their cylinder mowers that they are best know for. The Atco name is synonymous with the British gardening scene and the company has been awarded two Royal Warrants, the first in 1955 from Queen Elizabeth II and again in 1986, this time from HRH The Prince Of Wales.

    Robert Bosch GmbH acquired Atco-Qualcast Ltd in 1995 and this brought a modern approach to the manufacturing process with the cylinder mowers that the company is famous for changing tremendously, becoming more light-weight with a marked increase in usability and performance; the introduction of the now famous QX Quick Exchange Cassette System, for instance, allows gardeners to change their lawn application needs without changing machine. Not happy with manufacturing the highest quality products, Atco leads the way in environmental compliance, being the first garden machinery manufacturer to be awarded the environmental management standard BS EN ISO 14001.
