Lawnmower for small gardens

With no cord to get caught around the garden, you’ve got complete freedom to move safely and quickly wherever you want to go. And with up to 30 minutes’ run time** from a single charge, you can cover up to 150m² – that’s over half a tennis court! You won’t get caught out either. The interchangeable, 18V lithium-ion battery’s 4-LED display lets you know exactly how much charge you have left whilst in use.

Lightweight lawnmower

Weighing just 3.5kg fully assembled*, you can manoeuvre the SLM50 with ease throughout your garden. Being so compact and lightweight, you can comfortably push this mini lawnmower around your garden using only one hand, making it our best lawnmower for a small garden. It’s the perfect solution for cutting narrow areas and smaller spaces typically unsuited to larger models.

Your lawn, your way

The SLM50 has an adjustable height mechanism to help you achieve your lawn goals. Simply switch between 40mm and 50mm by manually adjusting the front and rear pair of wheels. And without the hassle of a grass box, grass cuttings can naturally decompose and self-fertilise the soil, keeping your lawn healthy.± It’s a win-win!

Keeping a low profile

We’ve kept our small electric lawnmower's height to a minimum so you can slide it beneath your trampolines, tables, chairs and other garden features. This saves you the hassle of moving your furniture, and leaves you with more time to enjoy your garden.

Safety first

Your safety is our priority, which is why the SLM50 has three safety features. The operational safety key must be in the ‘on’ position and the safety switch must be pressed in for the mower to start. Plus, the new ‘auto-off’ safety lock activates when the handle is raised to a high angle (over 66°), giving you peace of mind when storing your mower.

Omni-blade cutting technology

Our lightweight lawnmower uses a counter-balanced single rotary blade and has a 25cm (10 inch) cutting width. Made from carbon steel, the SLM50’s sharp and durable blade quickly rotates at a constant speed of 5200 RPM (max.).

Edge-cutting with ease

As well as assisting with manoeuvrability, having a chunky 14cm wheel on each corner means the blade can rest centrally in the base. The cutting blade can then reach the sides of the mower, helping you achieve a close cut even next to your walls and fences, or other edges of your lawn.

How you store your SLM50 is up to you. You can disassemble the mower with ease in a few simple steps and store the components separately. Or, our small lawnmower can be left assembled in the ‘park position’ with the safety lock activated.
