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 professional level cultivation and clean-up for lawn-thatch control, autumn renovations and weed control. The Stirling range 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™) and 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 so comfortable, the ambitious lawn expert will not be disappointed when the lawn is finished. 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. This height system is an even bigger advantage when selecting the depth for cultivation.

Allett’s quickest cartridge change ever means that removing the mower cartridge and securing 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-scuffage when turning.

The 6-bladed mowing cartridge comes as standard. There is an optional 10-bladed cylinder with a thinner front-edged blade for where a close shave is desired for example golf and 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 into wheeley-bins.

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