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, cordless 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.).

Are cordless mowers any good?

Cordless lawnmowers, specifically electric or battery powered models, are typically more economical, lighter and easier to store and assemble than traditional petrol lawnmowers. The SLM50 small cordless lawn mower is easy to push around and has a 30 minute runtime to quickly tackle small lawns.

What type of mower is best for a small lawn?

Electric and battery powered cordless lawnmowers are perfect for small lawns owing to ease in manoeuvrability, strong performance and no emissions. With a compact build and weighing only 3.5kg, the SLM50 is the best small lawn mower alternative for your garden.

What size is a small lawn mower?

A small lawn mower generally has a single rotary blade with a cutting width between 10 to 17 inches (25-43cm). The Gtech SLM50 small lawn mower has a cutting width of 10 inches and possess adjustable grass cutting heights, switching between 40mm and 50mm settings.
