Greenworks 40V Cordless Lawnmower G40LM35K2X (35cm) for lawns up to 400m² with 2 x 2Ah batteries and 40L bag
Product description
The essentials
If your grass is more “medium-sized” than tiny patio patches, but you still want to avoid petrol hassle, the Greenworks 40V cordless mower G40LM35K2X is designed to sit in that sweet spot. On paper, it’s aimed at lawns up to 400m², with a 35cm cutting width and a two-battery setup that lets you finish the job without recharging in the middle.
A cordless mower like this also changes the day-to-day feel: less noise, no fumes, and fewer messier moments than petrol. That’s the real appeal for many people—especially if you mow regularly and just want something that starts and goes.
Key points
This model is built around three practical ideas: it’s sized for up to 400m², it uses two 40V 2Ah lithium batteries, and it gives you a choice between collecting clippings or mulching them back. You get five cutting height positions, with a single lever to adjust from 25mm to 70mm, which makes it easier to respond to what your lawn is doing rather than forcing one setting.
You’ll also notice the storage and handling focus. It has large 18cm rear wheels for easier manoeuvring across different ground, plus a comfortable top handle. Fold it down for storage and you’re not wrestling a bulky mower in tight spaces.
There’s a lot to like here, but it’s worth adding a limitation: cordless systems depend on battery capacity and mowing conditions. If your grass is very long or dense, you may find you need to take it more slowly than you would with a petrol mower.
What stands out in use (and what to watch)
In everyday mowing, the 40L bag and 2-in-1 approach are the main drivers of convenience. When collection is your priority, you can fill the bag with clippings instead of leaving them scattered. When you’d rather return nutrients, switch to mulching for finer cuttings.
A small micro-scenario that helps put it into context: imagine a typical weekend mow where the lawn has grown evenly. You set the blade height using that single lever, mow in steady passes, then either empty the bag when it’s full or mulch on the go if you’re keeping up with growth. The process feels straightforward, without the staging you get from fuel mixing or dealing with hot engines.
What to watch is the “up to 400m²” claim in real terms. It’s a useful target, but it assumes fairly normal conditions. If your lawn includes rougher patches or you tend to cut in wide, fast passes, battery runtime can become the limiting factor.

Who it suits (and who should skip it)
It makes sense if you have a lawn up to around 400m² and you want a cordless mower that feels easy to handle and store. The fold-down handle and larger rear wheels are particularly appealing if you’ve got gates, uneven edges, or you need to move the mower over mixed ground.
It’s also a good fit if you already own—or plan to own—other Greenworks 40V tools, because the two 40V 2Ah batteries are described as usable across the Greenworks 40V range. That can reduce the need to buy multiple battery systems as your toolkit grows.
It may not suit you if your priority is maximum runtime regardless of conditions, or if you often mow very thick, overgrown grass where battery output could be tested. On this kind of cordless setup, you’ll usually get the best results when you mow consistently rather than letting things get out of hand.
Care & maintenance
Cordless mowers still need the usual “keep it clean and ready” routine. After mowing, it helps to clear grass build-up and check that the cutting area and bag aren’t clogged. Storing it folded and dry will also support longevity, especially for the battery system. Keep an eye on general wear as with any mower, and follow the manufacturer’s guidance for battery and charging handling.
Is it worth it?
Buying this Greenworks G40LM35K2X is a solid choice if you want a cordless mower aimed at lawns up to 400m², with a 35cm cutting width, a 40L collection bag, and the option to mulch using five cutting heights. The bundle of two 40V 2Ah batteries plus a charger is geared towards finishing the job comfortably without the “stop, wait, repeat” rhythm.
Skip it if your lawn regularly needs heavy cutting back or if you know you’ll be pushing the mower in harsher conditions where cordless runtime can become the bottleneck. In that case, you may want to look at an alternative approach that’s less dependent on battery capacity.
