Designed for the amateur sports arena such as cricket, bowls and croquet with smaller budgets the Stirling Sport offers our most exact and robust mowing to date with the Allett® cartridge system giving professional level cultivation and clean-up for thatch control, autumn renovations and weed control. The Stirling range drives a range of cartridges to cultivate your pitch 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 RotoShift™ 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 user will not be disappointed when the job is finished. Faster mowing speeds, if desired, are easily selected with the latest RotoShift™ control, but slowing for obstacles is effortless. The operator can also slow the speed right down when scarifying for example for greater efficiency.
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 inherited 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 10-bladed cylinder is fitted as standard with a thinner front-edged blade for where a close shave is desired for example cricket 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)
Allett Stirling 51 SPORT Feature Highlights:
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.
Frontroller locking kit
The front roller locking kit enhances stability and maintains a consistent height of cut, reducing flex during mowing. This results in a cleaner, more even finish—perfect for low-cut sports turf like bowls and cricket where surface precision is essential.
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.
Perfect for low cut pitches
The Stirling 51 Sport is ideal for low-cut turf clubs like bowls and cricket thanks to its 20″ width, precision cutting down to 3mm, and powerful dual-motor system. It delivers a clean, even finish and supports interchangeable cartridges for year-round turf care.
Height of cut range
The Stirling offers a wide height-of-cut range from 4mm to 50mm with the standard 6 blade cylinder cartridge, allowing you to fine-tune your lawn’s finish—from a close, clean cut to a longer, healthier trim—using the precise HiteRite™ micro adjustment system. For an even closer finish, the 10 blade cylinder cartridge has a height of cut range from 3mm to 50mm. Ideal for bowls clubs.
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.
