ALLETT KENSINGTON 17B Petrol Cylinder Lawn Mower

Achieve the Perfect Lawn with the Allett Kensington 17B Petrol Cylinder Mower

For gardeners who appreciate the craftsmanship of a well-tended lawn, the Allett Kensington 17B represents a step up in class from ordinary mowers. This high-spec, self-propelled petrol cylinder lawnmower is the perfect blend of traditional precision and modern engineering. Designed for those who won’t compromise on quality, it delivers clean, crisp results with unmistakable stripes that will set your garden apart. Built for serious domestic use, the Kensington 17B is more than just a mower—it’s a premium investment in your lawn.

Engine Power Tailored to Your Needs

The 17B is the medium-sized model in Allett’s esteemed Kensington range. It is available with a choice of two high-quality engines, each offering a smooth, dependable experience. You can opt for the powerful 127cc Briggs & Stratton XR550, or choose the equally capable 122cc Honda GX120. Both petrol engines are equipped with easy recoil start and provide consistent power for a wide range of grass conditions. Whether you’re tackling a fine ornamental lawn or a thicker, lush sward, each engine ensures consistent drive and excellent fuel efficiency.

With a 43cm (17-inch) cutting width and a fuel tank capacity of 2 litres, the 17B covers up to 700m² with ease. This combination of power and size allows for efficient mowing sessions, while the relatively low 96 dB(A) noise output ensures a quieter experience than many petrol mowers, which is especially valuable in built-up areas. The self-propelled system reduces physical strain, allowing you to focus on direction and finish rather than the effort of pushing.

Professional-Level Cutting with Precision at Its Core

One of the many things that sets this lawnmower apart is its six-bladed cylinder which delivers 79 cuts per metre—a level of accuracy rarely found outside professional groundskeeping. The cylinder rotates to create a scissor-like action, neatly slicing through each blade of grass to encourage denser, healthier growth. The result is a clean, uniform surface that looks refined and feels fantastic underfoot.

Using the micro height adjustment system, you can finely control your cut from 6mm to 32mm, allowing for seasonal changes or personal preference. The adjustment is smooth and intuitive, giving you total command over the final finish, whether you prefer a close croquet-lawn trim or a more natural look.

Crisp Stripes, No Compromises

Striking stripes are more than just visual flair—they’re a hallmark of quality mowing. The Kensington 17B achieves this with a smart roller setup: a zinc-plated front roller and a split steel rear roller with differential. This design ensures full-width contact and removes the risk of visible wheel marks, even around curves or on slopes. The rear roller’s differential allows the mower to turn smoothly without scuffing the lawn.

To enhance the finish further, this superior lawnmower includes a spring tine comb that lifts the grass just before cutting, ensuring a sharp, level result. An adjustable front-mounted rake removes surface debris and stimulates growth by gently lifting moss or thatch. Together, these features produce a beautifully striped and healthy lawn with long-lasting visual impact.

Advanced Cartridge System for All-Season Lawn Care

Another of the Kensington 17B’s fantastic features is Allett’s Quick Exchange (QX) cartridge system. This modular setup allows you to switch the cutting cassette for a variety of specialist lawn care cartridges—no tools needed. It’s a seamless way to expand the mower’s functionality, transforming it into a multi-purpose maintenance machine.

Optional cartridges include a scarifier, aerator, lawn brush, dethatcher, and Verticut blade, each helping to manage your lawn’s health throughout the year. For the most fastidious gardener, a ten-bladed cutting cylinder is also available, offering an even finer cut for pristine formal lawns. Whether you’re preparing your lawn for spring, reviving it after summer, or removing moss in autumn, the Kensington 17B adapts with ease.

Built to Last, Designed to Impress

Weighing 53.5kg with the grass box attached, this mower offers reassuring stability during use. Its solid construction ensures excellent traction across varied terrain. The frame remains balanced and composed, allowing for straight-line mowing without wobble or drag.

Comfort is also well considered. With three height settings on the handlebars, you can tailor the mower’s feel to your own height, reducing strain and improving posture. The handlebars fold down compactly for storage, making it easier to stow away in a tight shed or transport to another location. A standard auxiliary wheel kit lifts the mower slightly, making it suitable for slightly longer or uneven grass without compromising on performance.

The 62-litre grass collector is generously sized, allowing for extended mowing sessions with fewer interruptions. It’s quick to detach, easy to empty, and made from high-impact polypropylene, which is designed to withstand regular use.

British Craftsmanship, Guaranteed to Last

Proudly built by British-company Allett, one of the world’s leading lawnmower specialists, the Kensington 17B is the product of decades of innovation and refinement. The company’s reputation for creating finely engineered, single-cylinder walk-behind mowers is evident in every detail of this model. You’re not just buying a lawn mower—you’re choosing a machine that reflects tradition, quality, and a deep respect for beautiful lawns.

For even greater peace of mind, the Kensington 17B comes with a two-year domestic warranty, covering you for normal homeowner use. If you’re using it in a Sports Pro context, the warranty is for three months.
