The Allett Stirling 51 Cordless Lawnmower is a precision built cylinder mower for both lawn enthusiasts and professionals alike. Designed for large gardens, the Stirling 51 has a 20"/51cm cutting width, self-propelled drive with adjustable forward speeds, micro height of cut adjustments as well as featuring Allett's UltraChange™ interchangeable cartridge system for extensive lawn care.
The Stirling 51 is supplied with a 6 blade cylinder cartridge which has a height of cut range of between 5-50mm. An optional 10 blade cylinder cartridge can be purchased which has a height of cut range of between 4-20mm.
Operating the Stirling 51 is easy and intuitive thanks to the well balanced design and ergonomic handlebar controls. Adjusting the forward speed to accommodate for long straights and tight corners is really easy too, simply rotate the central dial and the speed immediately responds.
The Stirling boasts industry leading features that you'd expect from an Allett mower, including:
- An adjustable, spring-tine rake behind the steel front roller guides lateral growth into the path of the cutting cylinder
- Separate electric motors power the cartridges and the self-propelled drive to ensure an even cut by maintaining a constant cylinder speed, independent of the forward drive speed
- Front wheel kit for use when cutting longer grass
- Differential drive to prevent scuffing when turning
Ergonomic handlebars and a clever design makes for a perfectly balanced machine that's enjoyable to use time and time again. The handles are highly adjustable to ensure users of all heights can be accommodated. Both the height and the angle of the handles an easily be adjusted. When the mowing is done, a storage position for the handles reduces the space that the mower takes up in your shed or garage.
A front-mounted, mesh grass bag is both easy to securely mount on the front and easy to empty - even when full to the brim.
When you need to, the Stirling can be pulled backwards with ease thanks to the GlideDrive™ system which removes any resistance from the motor.

Interchangeable cartridges
The Allett Stirling is supplied with a 6 blade cutting cylinder as standard. In addition, there are 6 further cartridges that can be purchased that makes the Allett Stirling a true lawn care system. These cartridges are:
- 10 blade cutting cylinder

It's very quick and easy to remove and secure a new cartridge, taking just 15 seconds with no tools required.
Compatible with all 20" Allett Cartridges
In addition to being compatible with the Allett UltraChange™ cartridge system, the pulley supplied with the cylinder can be used to allow use of the cartridges from the Allett QC cartridge system. This means that if you already own Allett QC cartridges for the Allett Classic or Kensington mowers, the pulley supplied with the cylinder will allow those cartridges to fit into your Allett Stirling.
Ease of battery removal
The battery is easy to remove for charging.
Micro height-of-cut adjustments
Allett's HiteRite™ height-of-cut adjuster allows you to easily set the cut height to your exact requirements. The same adjuster is used to set the depth for cultivation tasks such as verticutting.
