The RYOBI 18V HP Brushless 40cm Lawn Mower combines powerful cutting with intuitive controls for maintaining small to medium-sized lawns. Responsive features automatically adjust performance, while the lightweight design enables easy handling. Together, these features provide a smoother, more enjoyable mowing experience.

This Kit includes an 18V ONE+ 4Ah Battery and 18V ONE+ 2A Charger.

HP Brushless cutting performance
The HP Brushless motor provides powerful and efficient cutting performance. Adaptive blade speed technology automatically adjusts to lawn conditions, while Turbo Mode provides extra cutting power when you need to take on tougher, thicker patches of grass.

Two battery ports keep one battery in use and a spare within reach, helping minimise changeover time.

Adjustable cutting heights
Choose from five cutting heights between 25mm and 100mm to suit different grass lengths and achieve your desired lawn finish.

Mulch or catch clippings
Switch between catching and mulching modes to suit the job and how grass clippings are managed. The built-in mulch plug makes changing to mulching simple. A 45L grass catcher means fewer stops while you perfect your lawn. It’s also easy to lift through the handles for emptying grass clippings.

Lightweight and easy to store
A rust-resistant polymer deck keeps the Lawn Mower down to just 11.6kg* for easy manoeuvrability. Collapsible handles enable compact vertical storage between mows, helping save valuable shed or garage space.

Versatile ONE+ power
The included Battery provides up to 30 minutes* of no-load runtime for the Lawn Mower. It’s compatible with hundreds of products from the ONE+ range. The Charger can be used with any battery from the ONE+ battery.

Available in-store and online from Bunnings Warehouse.

**Runtime tested under no load conditions. Results depend on the tool, battery and application.
