Allett Kensington 17 Petrol Cylinder Mower (Honda or Briggs Engine)
Designed for keen home gardeners with medium to large lawns, the Kensington Petrol Garden Mower is the ultimate cartridge machine in the Allett Homeowner Range. It is one of our most popular cylinder mowers and takes all the cartridges in the Allett range allowing for a range of lawn-care tasks using just one machine.
The Kensington 17 has a number of special features giving it an unbeatable cutting performance. The spring tine comb attached to the Kensington lifts the grass prior to cutting to ensure an even cut, and a zinc plated steel front roller and heavy steel rear roller help produce those beautiful, classic stripes that are the hallmark of an Allett lawn.
Equipped with a six-bladed precision cutting cylinder delivering 79 cuts per metre, the Allett Kensington 17 has a 17”(43.2cm) cut and is available with a choice of two different engine types: 127cc XR550 Briggs + Stratton petrol engine and 122cc GX120 Honda engine. It also features an infinitely variable micro cutting height adjustment from ¼ to 1 ¼ inch (6mm-32mm).
For enhanced lawn care, a range of optional additional cartridges can be fitted in place of the standard cutting unit. These include; the 10 bladed cutting cylinder, Aerator, Lawn Brush, Dethatcher, Scarifier and a Verticut cartridge.

Testimonials
James H. (Cheltenham, UK)
Stripes like a bowling green
This mower is outstanding. I’ve never seen my lawn look so sharp – the stripes are perfection. It starts easily, feels solid, and cuts like a dream. Worth every penny if you're serious about lawn care. The quality is leagues above anything I’ve used before. Total game changer for my garden.
Emily G. (Harrogate, UK)
Perfect for formal lawns
I bought the Kensington 17 for our formal front lawn and it's absolutely brilliant. It’s powerful yet smooth to operate. The cut height is super precise and it’s easy to adjust. The stripes it leaves behind get compliments weekly! A bit heavy, but that's the trade-off for a professional finish.
Michael S. (Oxford, UK)
Feels like a pro-level mower
As someone who’s quite fussy about the lawn, the Kensington 17 is a dream. It’s incredibly precise, and I love how the grass box fits perfectly. The stripes are sharp and defined, like something you'd see on a golf green. Pricey, but I have no regrets – it’s built to last.
