Product Details & Features

  • Cylinder mower - 6 blades
  • 20”/51cm cutting width
  • 5-50mm cutting heights
  • Cordless
  • Self-propelled variable speed
  • Up to 2-years warranty
  • Interchangeable cartridge system

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.

Choose from three battery and charger bundles:

  • Stirling 51 + 5Ah Battery + Standard Charger
  • Stirling 51 + 5Ah Battery + Rapid Charger Bundle
  • Stirling 51 + 10Ah Battery + Rapid Charger Bundle

Battery run times:

  • The 5Ah battery provides approximately 40 minutes working time (up to 850sqm)
  • The 10Ah battery provides approximately 80 minutes working time (up to 1700sqm)

Battery charge times:

  • To charge the 5Ah battery with the standard charger takes approximately 100 minutes and with the rapid charger approximately 40 minutes
  • To charge the 10Ah battery with the standard charger takes approximately 190 minutes and with the rapid charger approximately 70 minutes

Please note, the Stirling is fitted with a smooth front roller as standard. A grooved roller is available as an optional extra.
