The G40LM41 is a 41 cm Greenworks mower sold without a battery or charger. That makes it a targeted buy for people who already own a Greenworks 40V tool, such as a strimmer or hedge trimmer, and want to add a mower without paying again for packs. It collects into a 50 litre bag or mulches, and Greenworks rates it for medium lawns.

In its favour
- Switches between a large 50 litre bag and mulching the clippings into fine pieces.
- Cuts up to 500 m² with a 4 Ah battery, or 250 m² with a 2 Ah, says the listing.
- The handlebar folds down for storage, and a 3 year guarantee is listed.
Good to know
- Tool only, so you need a Greenworks 40V battery and charger before you can mow.
- The listing gives six heights in the bullets but five positions in the specs.
Our take
Battery choice sets the lawn size
Greenworks ties coverage directly to the battery you fit. A 40V 2 Ah pack is quoted for lawns of up to 250 m², and a 4 Ah pack for up to 500 m². If you already own a 2 Ah battery from another tool, it will run the mower, but a bigger lawn will need either a second pack or a 4 Ah upgrade.
The tool only approach reduces waste and storage space, a point the listing makes itself.
Bag or mulch
Clippings go into a large 50 litre bag or are mulched into fine pieces and returned to the lawn. A big bag means fewer stops on a medium lawn, while mulching saves trips to the green bin in the growing season.
Height is set by a single lever. The bullets mention six heights from 25 to 80 mm, while the specs list five positions and a lower maximum, so the exact count is unclear from the listing.
Handling and guarantee
Large 18 cm rear wheels help over uneven ground, and the handlebar folds down for storage. Amazon lists the weight at 18.5 kg. Greenworks includes a three year guarantee.
Other mulching options
The Greenworks 48V 41 cm mower has the same width and adds side discharge, two 4 Ah batteries and a twin charger, so it is the one to choose if you have no Greenworks batteries yet. The Ryobi OLM1833B is a smaller 33 cm tool only mower with a mulching plug for ONE+ owners. For a lawn near 500 m², the G40LM41 needs a 4 Ah battery to reach its stated figure, so work out which Greenworks 40V packs you already have before deciding. A second, smaller pack is another route if you prefer to swap rather than wait.
Verdict
The G40LM41 is a sensible pick if you already own Greenworks 40V batteries, ideally a 4 Ah pack, and have a lawn of up to 500 m². Without existing batteries, the Greenworks 48V 41 cm kit is simpler, and Ryobi ONE+ owners with a small lawn will get more from the OLM1833B.
