Break free from
the cord...

Enjoy complete freedom to move safely and quickly, wherever you want to go. With up to 30 minutes' runtime* from each 4-hour charge, you can cover up to 100m². The SLM50's 18V lithium-ion battery also has a 4-stage LED display, you can keep an eye on how much charge you have left whilst in use.

Single-handed operation.

Discover a new way to mow...

Manoeuvre with ease while the SLM50 does the hard work. At just 3.5kg fully assembled, you can comfortably push our mini lawnmower throughout your garden using just one hand. It's the perfect solution for cutting narrow areas and smaller spaces typically unsuited to larger models.

Designed with
you in mind.

"Lawnmowers typically take up a lot of storage space and can also be tricky to manoeuvre if you're maintaining a small patch of grass. So, we've kept ours compact with a central blade that reaches the sides of the mower, so you get a close cut even next to your walls, fences, or other edges of your lawn"



Keeping a low profile...

We've kept our small lawnmower's height to a minimum so you can slide it beneath your trampolines, tables, and other garden features. And with its low-profile reclining handle, you can reach even further underneath without needing to move. Lose the hassle of adjusting your furniture and find 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.


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