Main Review

We have completed a full review just below, and we have concentrated on the key features that you should consider before buying this model.

EAsy to use
easy to asssemble
battery life

Ease of Use

The good news about any cordless mower is that they are very easy to use. As long as you remember to have your battery charged, then simply plug it in, and away you go. There are no leads to worry about and you can take it just about anywhere you like as you don't need an electrical supply.

This model is light to move around and the wheels are big enough to get through the grass. It doesn't get right up to the edges and is about 1-2 cm shy of that. It is fast and does a very good job of cutting the grass.

Ease of Assembly

When we read through the reviews, the time varies as to how long it takes to assemble this mower. It does come in several pieces inside the box. The instructions are easy enough to understand. From start to finish, it will take about 15 minutes to set it up.

Some buyers have said that the grass box is really fiddly to put together.

Battery Life

Greenworks only make one kind of battery which suits all their gardening tools and they include hedge cutters, strimmers, blowers and chainsaws. It is a 40V battery and the manufacturer states that it is designed to last up to 20 years. They supply two 2AH batteries with is model though you can also get a 4 or 6AH from them.

Their 40V batteries are enough power to cut around 600 square metres, of lawn. To be fair, not many people have gardens this size, so you should be able to get your lawn mowed with a single charge. A single charge will cost you around 7p on average. (This will vary depending on your supplier)

Why Pick this Mower?

It's Cordless

By owning a cordless lawnmower of any type or brand you instantly get a few clear benefits:

  • It is environmentally friendly when compared to petrol mowers
  • No trailing leads to worry about and no extension leads either
  • The battery and charger can be used with other compatible brand tools - that means you can buy those as tool only at a much cheaper price
  • Cordless mowers are very quiet when compared to other types of mowers.

Price Comparison

Cordless mowers vary in price from £150- £900. That will depend on the brand, the features and the quality of the build. Mowers with wider cutting widths are more expensive. Having more height adjustments make these more expensive. Being IPX4 rated for use in wet weather also make them more expensive.

This Greenworks model sits at around £300 depending on where you buy it. For the mower, 2 batteries and a charger, this is a very good price. Especially as this model has a mulchong feature.

Always be aware of exactly what you are buying and always try and do direct comparisons. To price match this model, you have to look at offers that also have 2 batteries and a charger. When we did that, we found that this model was a bit above the average price of £250, so in our opinion, solid value for what you are getting.

The Size of your Lawn

It doesn't take long to work out the size of your lawn. You just simply pace it out. A good stride is about a metre long so when we did our front garden it was about 6 metres x 6 metres, and the back garden was 5 metres by 20 metres.

A simple multiplication tells us that the front garden is (6x6) 36 square metres and the rear is (5x20) 100 square metres. So we need a mower that can mow up to around 136 square metres with a single charged battery.

You should do the same as that will help you buy the right cordless mower for your needs.

This model can handle up to 600 square metres from one charge.

Our Verdict on the Greenworks G40LM41K2X Cordless Lawn Mower

This Greenworks model sells consistently online and we believe it is good value for money as you get the mower, 2 batteries and a charger.

If you have a garden lawn area of less than 600 square metres, this mower is going to be able to handle that on a single charge.

2 hours for a charge is a bit slow, but with 2 batteries, you can get them both charged up so as you are not without power.

In terms of construction, it is OK without being anything special. Like many mower manufacturers they tend to use hard plastic for the parts (wheels, deck clips and grass box) - sadly over time these do break.

For anyone though, who just wants the simple convenience of pulling out a lawnmower, getting the grass cut quickly, and then storing it away to the next time, this one will do the job nicely. There are better and higher quality models out there, but they will also mean having to take a few more notes out of the wallet.
