Allett Kensington 17K Petrol Cylinder Lawn Mower
Impeccable breeding, impeccable performance, the Allett Kensington 17K lawn mower is undoubtedly one of the best petrol cylinder mowers on the market today. This superbly built machine features a powerful engine and the revolutionary Qc system.
This Quick Exchange system on the Allett Kensington Expert 17K allows you to not only remove the blade cassette for re-grinding or replacement purposes, but also to turn your lawnmower into a powered rake by substituting the standard six-bladed cassette with the Qc Lawn Scarifier cassette accessory. Also available is the 10 multi-bladed Qc cassette to ensure an even finer cut.
The Allett Kensington 17K is controlled by a three-way drive facility which allows the blades to be disengaged without stopping the engine, convenient for emptying the grassbox and for powered manoeuvres around the garden. Also, when mowing in awkward corners or around trees, you can disengage the drive for manual control.
Features such as foam-cushioned handles, a larger, more manageable throttle and micro-set cutting height adjuster are all designed to make mowing the lawn a positive pleasure. For longer grass, you can attach the supplied side wheels which then elevate the mower to provide an effortless cut. The spring tine comb also lifts the grass prior to cutting to ensure an even cut, and a stainless steel front roller and heavy steel rear roller produce those beautiful, classic stripes that are the hallmark of an Allett lawn.
All Allett cylinder lawn mowers are backed by a 2-year warranty which can be extended to an industry-leading 3-year warranty by having your machine serviced by an Allett dealer at the end of the first and second season of use. The warranty will then be extended automatically to 3 years. This extended warranty demonstrates our faith in the enduring quality of our products and enables customers to have complete confidence in their new Allett lawn mower.
Features:
- All models can be transformed into powered rakers by fitting the Qc™ Lawn Scarifier cassette (available as an optional accessory).
- 3-way drive system allows independent cylinder and rear roller engagement.
- Infinitely variable micro cutting height adjustment from 0.24in to 1.4in (6mm-32mm)
- Large capacity grassbox.
- Powered by a 3hp Kawasaki four-stroke single cylinder petrol engine
- Incorporates an adjustable but static rake to tease out dead material and moss
- Two-year domestric warranty (can be extended to 3years)
An additional 6 interchangeable cartridges for the Allett Kensington can be ordered alongside this mower from the accessories section, creating the perfect lawn ALL YEAR ROUND.

About Allett
Allett are a wholly British-owned company who take great pride in their heritage. They’ve specialised in the design and manufacture of cylinder lawn mowers for 50 years and are incredibly well known for producing machines which create beautiful ornamental lawns and perfectly cut sports turfs.
Horticultural engineer and company founder Reg Allett, created the first 36” cylinder lawn mower prototype in 1965 which soon become the professional groundsman’s mower of choice. The distinctive black, silver and gold livery of Allett machines is now recognised throughout the world.Throughout the 70s, 80s and 90s the 20”, 24”, 30”, 34” and 42” models followed and by early in the new millennium the professional range, which was suitable for golf and bowling greens, sports stadiums, cricket wickets, and private parks and gardens, was launched too.
In August 2007, Allett was acquired by the privately owned Turfmech Group , and their production moved to Turfmech’s state-of-the-art manufacturing centre in Hixon, Staffordshire. This gave them top-of-the-range materials to work with and expand the brand entirely. In May 2011, Bosch Lawn and Garden granted Allett the manufacturing rights to Atco and Suffolk Punch, the former petrol and electric pedestrian cylinder lawn mowers. These have now formed the new Classic and Expert green and gold lawn mowers. Thanks to the addition of the Classic and Expert ranges, Turfmech are now the biggest manufacturer in Britain of petrol-engine cylinder lawn mowers.
Allett cylinder lawn mowers cut grass using a series of sharp rotating blades as opposed to a basic rotary blade. A scissor-like action where the cutting cylinder traps blades of grass between the spinning blades and a static ‘bottom blade’ produces a crisp, clean cut which heals much quicker than it would with a rotary lawn mower, leaving healthier looking grass. Allett lawn mowers also produce the highly manicured ‘striped effect’ which is sought after all over the world.
The Allett brand of professional walk-behind cylinder lawn mowers are now market leaders within their sector. Their machines have been adopted by professional groundskeepers of rugby and football clubs, cricket clubs and even Wimbledon. Allett have even been chosen by the Commonwealth War Graves Commission to supply machines for the upkeep of their immaculate cemeteries all over the world.
