The Allett Westminster 20H is a superb, close-cut precision cylinder mower ideal for maintaining fine-turf sports surfaces and first-class ornamental lawns across up to 350 square metres.  Achieve a velvety-smooth finish on bowling and golf greens, cricket wickets and pristine lawns.

Powered by an economical, low noise, easy-start Honda 196cc petrol engine with recoil start, the Allett Westminster 20H self-propelled cylinder mower has a 50.8cm (20") cutting width.  It is equipped with a 12-bladed cutting cylinder which produces an impressive 145 cuts per metre, leaving a fine, level and even finish, enhanced by an adjustable static rake that lifts the grass immediately before cutting.  Classic stripes are achieved thanks to the aluminium double section rear roller with tapered edges, and zinc plated steel front roller with bearings.  The height of cut is adjustable via a micro-adjust knob between 2.4mm and 19mm.

The Allett Westminster 20H is fitted with a large 84 litre grass box equipped with a specially designed cradle which allows it to be easily rolled on and lifted off of the mower without spilling the grass cuttings.  Three way drive stops the blades without halting the engine, allowing for powered moving of the mower around the garden, useful when emptying the grass box or positioning the mower before and after use. The foam-cushioned handles are fully adjustable and also fold for more compact and convenient storage.

An optional side wheel kit and stand is available.  The wheels simply slide onto a pair of stub axles protruding from either side of the rear roller, supporting the mower and enabling safe, powered transport across hard/uneven surfaces without fear of damaging the rear roller or blades. 

Hand-built in the UK, the Allett Westminster 20H boasts a robust design and quality finish ensuring many years of reliable performance, backed up by a two year warranty.

ABOUT ALLETT....

Allett takes great pride in its heritage. It is a wholly British-owned company which, for almost fifty years, has specialised in the design and manufacturer of precision, single-cylinder, walk-behind mowers. Through its technological achievements, the company has helped produce better, more consistent sports turf surfaces and finer, more beautiful ornamental lawns.

The first Allett prototype was a 36" wide machine designed, built and tested in 1965 by horticultural engineer, Reg Allett who, a year later, manufactured and sold his first production mower. Within two years of its launch, the Allett 36" was the professional groundsman's mower of choice and, by the late 1960s, these precision machines were cutting the outfields of every English Test Match venue and many county cricket grounds. They were also trusted to prepare the pitches of leading football and rugby clubs and were specified for use at other sports venues, country estates and public parks throughout the UK, Ireland and continental Europe.

Throughout the 1970s, 80s and 90s, Allett continued to develop its professional mower range with the introduction of the 20", 24", 30", 34" and 42" cut machines and by the early years of the current millennium, the professional cylinder mower range comprised specialist mowers for golf and bowling greens, sports stadiums, cricket wickets and outfields as well as public and private parks and gardens. In addition, the company was honoured when the Commonwealth War Graves Commission chose Allett mowers almost exclusively to maintain the grass within its immaculate cemeteries in Britain and all over the world.

In August 2007, the company was acquired by the privately-owned Turfmech Group and Allett mower production was moved to Turfmech's state-of-the-art manufacturing centre in Hixon, Staffordshire. Importantly, brand heritage expressed through its distinctive black, silver and gold livery was maintained and continues to be recognised throughout the world.

In May 2011 Allett acquired, from Bosch Lawn and Garden, the design and manufacturing rights to the former Atco and Suffolk Punch branded petrol and electric pedestrian cylinder mowers. These have now formed our new “green and gold” Classic and Expert cylinder mower ranges.

The addition of the new Classic and Expert domestic and semi-professional cylinder mowers to its portfolio makes Turfmech the largest manufacturer of pedestrian petrol-engined cylinder mowers in Britain, delivering sustained technological advances and complete peace of mind.

Today, the Allett brand of professional walk-behind cylinder mowers are leaders within their various market sectors, providing users with expertly-built, reliable, well-proven grass-cutting machines which produce a seemingly effortless first-class finish to every lawn on which they are used.

Each and every one of Allett's powerful, smooth running yet quiet machines is supported by exceptional pre- and after-sales care and attention, a service the company is delighted to offer to its customers worldwide.
