ALLETT KENSINGTON 20H Petrol Cylinder Mower (Honda Engine)

Allett Kensington 20H Petrol Cylinder Mower: Refined Lawncare from a Prestige Brand

If you’re aiming for a truly refined finish to your lawn, the Allett Kensington 20H Petrol Cylinder Mower (Honda Engine) has everything needed to achieve it. Designed for true lawncare connoisseurs, this premium cylinder mower combines classic British heritage with advanced engineering and a user-friendly design.

Part of the prestigious Allett Homeowner Range, the Kensington 20H is far more than just a premium domestic lawnmower. Thanks to its cartridge-based system, this single machine can take care of aerating, scarifying, and more, making it a shrewd long-term investment in the health and appearance of your garden.

Reliable Honda Engine Performance

Designed for lawns up to 900m² (9,688 ft²), the Kensington 20H cylinder lawnmower is fitted with a robust 122cc Honda GX120 petrol engine, known for its reliability and smooth operation. With recoil start and a generous 2L fuel tank, it provides consistent performance across longer mowing sessions.

The twin-split bale bar allows you to engage the cutting cylinder and roller drive independently or together. This gives you precise control when manoeuvring or working in tighter areas, helping you maintain a clean and even finish throughout.

User-Friendly Design for Effortless Handling

This premium petrol mower is designed with a self-propelled drive system to reduce operator fatigue on medium to large lawns. There’s no need to push as the machine moves forward automatically, leaving you free to guide it to the perfect finish.

Comfort is further enhanced by a height-adjustable handlebar. There are three height positions to choose from, so you’ll be able to achieve a healthy posture. The handlebar can be folded too, ensuring space-saving garden storage.

Precision Cylinder Cutting System

At the heart of the machine is a Quick Cartridge™ 6-blade cylinder system with a 51cm (20-inch) cutting width. This setup delivers a fine, scissor-like cut, producing an impressive 79 cuts per metre (73 per yard).

Cylinder systems deliver a much cleaner cut than rotary blades. This promotes healthier growth and a neater finish, making the Kensington 20H ideal for formal lawns where presentation truly matters.

The micrometric height-of-cut adjuster offers a precise range from 6mm to 32mm (1/4 – 1 1/4 inches). This allows you to fine-tune your cutting height with confidence, ensuring consistent results right across the lawn.

Spring Tine Rake for Enhanced Finish

Positioned between the front roller and cutting cylinder is a spring tine grass rake, which lifts and prepares the grass before cutting. It also clears debris before the blades begin cutting.

This feature improves cutting accuracy and encourages a more upright lawn structure. The result is a cleaner finish and healthier grass over time. It is depth adjustable, allowing you to adapt it to your lawn’s needs.

Rollers Designed for Classic Stripes

If you’re after that traditional striped finish, the Kensington 20H features a zinc-plated steel front roller and double-section steel rear roller to deliver it with confidence.

The rear roller includes a differential, allowing for smooth turns without scuffing the turf. This design improves traction and control while producing crisp, defined stripes that elevate the overall look of your lawn.

Large Capacity Grass Collection

The Allett Kensington 20H is fitted with a large 70-litre polypropylene grass box, designed to withstand regular use. Its generous capacity reduces the need for frequent emptying, helping you maintain momentum while mowing.

The impact-resistant polypropylene construction ensures long-lasting performance, even under demanding conditions.

A Complete Lawn Care System

One of the many standout features of the Kensington 20H lawn mower is its compatibility with Allett’s interchangeable cartridge system. We sell six cartridges as optional extras, including an aerator, scarifier, dethatcher, lawn brush, verticutter, and 10-blade cylinder, so this machine can handle a wide range of lawn care tasks.

Switching between cartridges is quick and straightforward, allowing you to adapt the machine to seasonal requirements. This transforms the Kensington 20H from a high-end mower into a comprehensive lawn care solution.
