The Allett UC (Ultra-Change) cartridge system is a revolutionary feature designed specifically for the Allett Stirling mower range, transforming a high-quality cylinder mower into a complete lawn care system. Built for speed and convenience, the UC system allows you to swap between a wide range of cartridges—such as scarifiers, aerators, brushes, and dethatchers—in less than 15 seconds, all without the need for tools. This makes it incredibly easy to adapt your mower to suit the needs of your lawn throughout the seasons. The Ultra-Change system is perfect for users seeking maximum versatility, efficiency, and professional-level results from a single machine. With the Stirling range and UC system combined, maintaining a healthy, beautifully striped lawn has never been more convenient.

The RC (Removable Cartridge) system is Allett’s latest quick-change cartridge design, developed specifically for the Cambridge mower. It allows users to switch between different lawn care functions—such as mowing, scarifying, or brushing—quickly and easily. Changing cartridges takes less than a minute, and the only tool required is a standard 5mm Allen key. Thanks to the streamlined design, there's no need to remove the side cover, making the process faster and more convenient. The RC system makes the Cambridge a highly versatile machine for year-round lawn care.

The QC (Quick Cartridge) system is Allett’s innovative interchangeable cartridge design, enabling you to switch between different lawn care functions using a single machine. While the Kensington range is compatible with the full selection of QC cartridges—including scarifier, aerator, verticutter, lawn brush, and more—the Liberty 30 is limited to accepting only the scarifier cartridge. Although more restricted, this still provides added functionality for maintaining lawn health. Swapping cartridges takes around five minutes and does require basic tools, but the process is straightforward and well-supported by Allett’s design, making seasonal maintenance easy and efficient.
