The Cordless Lawnmower 40V is a battery powered rotary mower built for gardens up to 400m². A brushless motor runs on two 20V batteries working together to produce 40V of power. No petrol and no trailing cord. Just charge the batteries and start mowing.
It cuts a 43cm wide path and handles long, uneven grass without stalling. The cutting height adjusts across 6 positions from 25mm to 75mm, so you can set it low for a summer trim or higher for autumn growth. At just 14.5kg it is far lighter than a petrol mower, making it easier to push around flower beds and tight corners.
A 50L grass box with a volume indicator cuts down on how often you need to stop and empty it. The hybrid box design improves airflow so clippings collect properly instead of clogging the chute. Two 4.0Ah batteries, a fast dual charger and a 365-day warranty come as standard.
The mower runs on two 4.0Ah lithium-ion batteries working together at 20V each to power the 40V brushless motor. Several customers report finishing a full garden cut and still having a quarter of the charge left. One reviewer mowed both their front and back garden and still had plenty of battery life remaining. Actual runtime depends on grass length and garden size, but for gardens up to 400 square metres the dual battery setup is designed to get the job done in one session. The included fast dual charger means both batteries charge at the same time rather than one after the other.
Most buyers found assembly straightforward. One customer said it was "easy to put together and light but sturdy." Another mentioned the instructions could be clearer, specifically around the handle bolts, which need to be fitted carefully to avoid issues. The battery compartment is simple though - it takes both 20V batteries at once to deliver the full 40V power output. No tools beyond what's included should be needed. Expect basic assembly similar to most flat-packed mowers, nothing overly technical.
This is built for gardens up to 400 square metres. The 43cm cutting width helps here - a wider path means fewer passes to cover the same area compared to narrower mowers. Combined with the 50L grass catcher, you can cut a decent sized lawn before needing to stop and empty the box. One reviewer mentioned handling a "wild lawn" with grass up to knee height in places, uneven and bumpy, without trouble. So it's not just for small neat lawns - it copes with rougher conditions too.
Multiple reviewers directly compared this to their old petrol mowers and preferred the switch. Common reasons include being lighter at just 14.5kg, easier to push and quieter during operation. There's no fuel to buy, no fumes and no pull-cord starting. One customer called it "much lighter and easier to push than my old petrol mower." Another appreciated not having a cord to trip over or tangle, which is a common complaint with corded electric mowers. The trade-off is battery dependency, but the dual 4.0Ah batteries seem to handle most garden sizes without issue.
There are 6 adjustable positions ranging from 25mm to 75mm. This range covers a low summer trim right through to a higher autumn cut when grass needs more length for health going into colder months. Reviewers found the height adjustment easy to use. This flexibility matters because cutting grass too short in summer heat can stress the lawn, while a higher fssetting works better when growth slows down later in the year.
Yes, it includes a 50L grass catcher made from half-plastic material. It has a built-in volume indicator so you can see when it needs emptying without having to stop and check manually. The hybrid box design is meant to improve airflow, which helps with collection efficiency. Most reviewers didn't report problems, though one customer did mention difficulty fitting the box onto the mower, while otherwise finding the mower performed fine. If you do encounter resistance fitting it, check the box is aligned correctly, as this seems to be the main sticking point from feedback.
The package includes the mower body, two 4.0Ah lithium-ion batteries, a fast dual charger and the 50L grass catcher. Carton weight is 14kg with packing dimensions of 80.4cm x 48.4cm x 40cm. NETTA backs this product with a 365-day warranty and customer support is available 7 days a week. This gives buyers a full year of cover from the purchase date, which is reassuring for an electrical garden tool that sees regular seasonal use.
At 14.5kg, it's noticeably lighter than most petrol equivalents, which often weigh considerably more due to the engine and fuel tank. The lightweight build was repeatedly praised in reviews, with one buyer noting it was "easier than my previous hover mower" thanks to the wheels. Dimensions are 47cm depth, 44cm width and 78cm height, making it compact enough to store in a shed or garage without taking up excessive space. For gardens with tight corners or raised borders, the lighter weight makes directional changes less of a strain on the arms and back compared to bulkier mowers.
