Product Description

Allett’s precision, single-cylinder machines have for decades been the lawnmower of choice for a wide range of people and organisations, from top Premier League football clubs and professional groundsmen to keen home gardeners, united by a commitment to maintaining a superb surface on their lawns and turfs; something for which Allett mowers have a deserved reputation. By investing in one of Allett’s Kensington petrol mowers, including the 14K, 17K and 20K, you therefore not only acquire a first-rate machine, but also join a proud tradition of gardeners dedicated to achieving a luxurious manicured finish on their lawns.

The Kensington 20K has the largest cutting width of any of Allett’s Kensington range at 51 cm, and is fitted as standard with a six-blade “Quick Cartridge” cutting cylinder capable of delivering up to 79 cuts per metre. The clean and efficient cut offered by the Kensington 20K can be further improved by the addition of the optional ten-blade cutting cylinder (available separately), which slots quickly and easily into place and increases the clip rate to around 131 cuts per metre. The 20K’s cutting height can be adjusted to precision to suit your needs, over a range of 6mm-32mm, and the inclusion of a static grass rake in front of the cutting cylinder lifts grass to ensure a finer and more even cut.

In addition to the cutting cylinder, the self-propelled Kensington 20K’s potent 98cc Kawasaki four-stroke petrol engine also supplies power to the rear roller, thereby taking much of the effort out of mowing larger lawns. The front and rear stainless steel rollers also work to improve stability and manoeuvrability, as well as ensuring a crisply defined stripe effect on your finished lawn. All mowers in Allett’s Kensington range can be quickly and easily fitted with a scarifier cartridge for the removal of leaf litter and other detritus from the surface of your lawn. The British manufactured Kensington 20K also comes with Allett’s two year warranty on parts and labour, and is ideal for anyone seeking to keep their lawn in peak condition.

About Allett
Allett is a wholly British-owned company (as British as queuing for a cup of tea or eating fish and chips while standing on a rainy beach) with a longstanding tradition in the design and manufacture of precision, single-cylinder, walk-behind mowers. Founded by Reg Allett almost half a century ago, Allett has since become a byword for a finely mown lawn across the UK, Ireland and continental Europe, and the distinctive black, silver and gold livery of Allett machines is recognised throughout the world. In fact, if you have ever stopped to admire the crisp, luxurious, striped finish on the ornamental lawn of an old country estate there is a good chance that one of Allett’s high quality cylinder lawnmowers was used to achieve it.

Allett’s cylinder mowers cut using a series of sharp rotating blades rather than a basic rotary blade. The cutting cylinder traps blades of grass between its spinning blades and cuts with a clean, scissor-like action, producing a crisp cut which heals more quickly for a healthier lawn. Thus, as well as the iconic stripe effect, cylinder mowers also ensure the most pristine finish possible, making them perfect for maintaining golf and bowling greens, sports stadiums, cricket wickets and outfields as well as public and private parks and gardens.

This has led to Allett machines being adopted by professional groundskeepers in all walks of life, including at many leading rugby and football clubs, country cricket clubs and the All England Club, Wimbledon. In addition to this, Allett has also been bestowed with the honour of being chosen by the Commonwealth War Graves Commission to supply mowers for the upkeep of its immaculate cemeteries around the world.

More recently, Allett acquired the design and manufacturing rights for the former Atco and Suffolk Punch branded petrol and electric pedestrian cylinder mowers. These now form the basis for Allett’s Classic and Expert mowers, providing an even more extensive range of both domestic and semi-professional machines from which to choose. Thus, whatever your particular requirements, if you need to achieve a truly flawless striped finish on your lawn there is almost certainly an Allett machine ideal for you.
