The Buckingham 20H features a six-blade cutting cylinder, variable micro-cutting height adjustment, front and rear rollers to produce a striped finish, and a cutting width of 51cm, making it a machine ideal for lawns of up to 350 square metres.


Allett are a company with almost fifty years of experience of creating hard-working, high quality cylinder mowers, precision engineered to leave the pristine striped finish seen on formal lawns, parks, gardens and even cemeteries across the United Kingdom and Europe. In the Buckingham range, including the 20H, 24H and 30H, Allett have created a robust, general-purpose cylinder mower ideal for the serious home gardener and the semi-professional user alike.

The Buckingham 20H features a six-blade cutting cylinder, producing a scissor-like action wherein individual blades of grass are caught between the moving blades of the cylinder and a single stationary blade at a rate of approximately 73 cuts per minute. This mechanism produces a cleaner cut, resulting in a finer surface and promoting healthy lawn growth. The 20H also features variable micro-cutting height adjustment, ranging from 5mm-35mm. The iconic striped finish commonly associated with cylinder mowers is produced by the 20H’s zinc plated steel front roller and double sectioned steel rear roller, which together work to ensure smooth operation, drive the machine forward, and to create a well defined stripe and even finish.

Both the cutting cylinder and the self-propulsion system on the Buckingham 20H are powered by a 196cc Honda four-stroke single cylinder petrol engine, with traditional recoil start system and a generous 3.1 litre fuel tank. The 20H has a cutting width of 51cm, which in combination with the drive system makes it a machine ideal for lawns of up to 350 square metres. This, however, can be further enhanced by the addition of the optional Autosteer trailing seat, which allows the operator to sit whilst mowing. The Autosteer trailing seat’s in-built steering system ensures that the seat always follows the line of the mower when navigating around borders and obstructions on a lawn, and is available for all models in Allett’s Buckingham range.

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.
