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.

Frequently Asked Questions
What size lawn is the Allett Stirling 43 suitable for?

What is the battery life of the Allett Stirling 43?
The mower runs on the EGO 56V battery system. With the recommended 5.0Ah battery, you can expect a runtime of approximately 30-40 minutes. Using a larger 10.0Ah battery can extend this to 50-60 minutes, depending on lawn conditions.
