Designed for the home lawn enthusiast with medium to large lawns, the Stirling range of expert mowers offer our most exact and robust mowing to date, with the Allett® cartridge system giving near professional level cultivation and clean-up for lawn-thatch control, autumn renovations and weed control. The Stirling drives a range of cartridges to cultivate your lawn deeper, faster and with greater precision with unprecedented control and new levels of comfort.

Powered by the EGO 56V battery system using their unique 'Keep Cool'™ Technology, the mowing and cultivation cartridges are driven by a separate powerful electric motor(ProDrive™). The rear roller drive speed is controlled by the handlebar mounted speed control, which can be adjusted on-the-move, so the correct forward speed is selectable to achieve the best results.

The Stirlings are perfectly balanced machines with ergonomical handlebars which are extremely comfortable. Faster mowing speeds, if desired, are easily selected with the latest RotoShift™ control, but slowing for obstacles is effortless.

Allett’s new HiteRite™ height of cut selection gives micro adjustment with a clear scale of the height selected. There is also a separate section of the scale for selecting the depth when using the cultivation cartridges.

Allett’s quickest cartridge change ever means that removing the mower cartridge and fitting the other cartridges takes just seconds, and no tools are required with the patent-applied for Ultra-Change system (Int Pat App WO 2023/079275)

A thicker, more rigid bottom blade SureBlade™ system gives easier and more accurate blade setting. Combined with quiet electrical system, this is Allett’s quietest mower ever. Your neighbours will love your mower too.

Features expected from Allett’s Kensington range are standard like the adjustable, spring-tine lawn rake behind the steel front roller, front wheel kit and a split rear roller with differential drive for assistance in straight-lining and reduced turf-scuffing when turning.

The 6-bladed mowing cartridge comes as standard. There is an optional 10-bladed cylinder with a thinner front-edged bottom blade, which can achieve a closer shave if desired, for example when used on bowling greens.

The handlebar controls are designed for extra comfort, and a single hand lever gives instant adjustment for comfortable heights for users of all sizes. The new front-mounted grassbag is light, easy to mount and the tapered design empties with ease, even when packed full with clippings .

The Stirling can be pulled back with ease without resistance from driving the motor with the GlideDrive™ system (Patent Number GB2613951)

Note the mower is fitted with a smooth front roller as standard. The grooved roller is available as an optional extra 

15 Second cartridge change

The Ultra-Change™ system allows cartridges to be swapped in under 15 seconds without the need for tools. This quick-change design makes it simple to switch between tasks, offering speed, efficiency, and convenience for maintaining every aspect of your lawn with zero hassle.

Poweredby a 56v Ego battery

The Allett Stirling is powered by the advanced EGO 56V battery, which is fully interchangeable across the complete EGO garden tool range. This compatibility offers outstanding flexibility and convenience, allowing you to operate multiple tools efficiently with one system.

Deeper cultivations than ever before

The Allett Stirling enables deeper cultivations than ever, reaching depths of up to 10mm. This capability is perfect for intensive lawn care tasks such as thatch removal, aeration, and soil improvement, delivering professional-level precision and outstanding results.

30-60 Minutes mowing time

The Allett Stirling provides up to one hour of mowing on a single charge, depending on the battery selected. This generous runtime supplies ample power to handle medium to large lawns without interruption, ensuring efficient operation and consistently high-quality results.

Height of cut range

The Allett Stirling offers a wide 4mm–50mm height-of-cut range with its standard 6-blade cartridge, adjustable via the precise HiteRite™ micro system. For an even closer finish, the 10-blade cartridge provides a 3mm–20mm range, making it ideal for bowls clubs and fine lawns.

7 UC cartridge options

The Allett Stirling works seamlessly with seven Ultra-Change™ (UC) cartridges, providing true all-in-one versatility. Easily switch between mowing, scarifying, aerating, brushing, verticutting, dethatching, and raking for comprehensive, year-round lawn care with one machine.
