Professional Results for the Home Enthusiast
The Allett Stirling 43 is engineered for home gardeners who demand a professional-quality finish on medium to large lawns. This expert mower delivers Allett’s most exact and robust performance to date, using a precision 6-blade cylinder to achieve a crisp, clean cut. It features a split rear roller with differential drive, ensuring perfect stripes while minimising turf scuffing during turns. This model is ideal for achieving a pristine lawn appearance through precise mowing and effective lawn care.
Advanced Battery Power and Control
Powered by the highly-regarded EGO 56V battery system with ‘Keep Cool’™ Technology, the Stirling 43 offers quiet, emission-free operation without compromising on power. The mower utilises a dual-motor ProDrive™ system, with one brushless motor driving the cutting cylinder and a separate motor powering the rear roller. This allows for independent speed control via the handlebar-mounted RotoShift™, letting the operator adjust forward speed on-the-move to match conditions perfectly, from a brisk mow to slower, more controlled cultivation tasks. The GlideDrive™ system also allows the mower to be pulled backwards without resistance.

Please note: This product is sold as ‘Tool Only’. Batteries and chargers are available separately in various kit options.
Unmatched Versatility with the Ultra-Change™ System
The Stirling 43’s standout feature is its patented Ultra-Change™ cartridge system, which allows the operator to switch from mowing to intensive lawn care in under 15 seconds, with no tools required. This transforms the mower into a complete lawn maintenance solution. It is compatible with a wide range of 17″ Allett cartridges for deeper and more precise cultivation, including a scarifier, aerator, dethatcher, and lawn brush. For an even finer cut, suitable for ornamental lawns or bowling greens, an optional 10-bladed cylinder is also available.
Engineered for Precision and Comfort
Every detail of the Stirling 43 is designed for accuracy and user comfort. The new HiteRite™ height of cut selection provides step-less micro-adjustment with a clear scale, ensuring you can set the perfect height from 5mm to 50mm. The SureBlade™ system features a thicker, more rigid bottom blade for easier and more accurate setting. The handlebars are ergonomically designed with multiple grip positions and are easily adjusted for any user height. A lightweight, 62-litre grassbag is easy to handle and empties cleanly, completing a seamless and enjoyable mowing experience.
