Greenworks Cordless Electric Lawn Mower

As battery technology continues to improve, so too does the overall performance of electric cordless lawn mowers. Many of the initial drawbacks – short runtimes and long charge times – are becoming a thing of the past, with batteries performing better than ever.

Perhaps one the best examples of this is the Greenworks Cordless Mower. Equipped with one of the best batteries on the market, the mower boasts some the fastest charge times, allowing you to recharge the battery in a fraction of the time that it takes other models.

The 40V mower has a lot going for beyond the quick charging battery, including ample cutting power, various cutting heights, a wide steel blade for fast mowing, and even a mulching function to give the lawn some added nutrition.

Of course, with trusted brands like Flymo and Bosch dominating the market, is a mower like this from a lesser known brand worth your investment? Let’s take a closer look at the Greenworks 40V cordless mower to find out!

Features

Battery and Motor

  • 40V 2Ah Lithium-Ion Battery
  • 35cm Cutting Blade
  • 5 Cutting Heights (20mm-70mm)
  • Mulching Function
  • 40L Grass Box
  • Interchangeable Battery with other Greenworks Power Tools

The mower is fitted with an electric motor powered by a robust G-Max 40V 2Ah lithium-ion battery, offering roughly 30 minutes of runtime. As a result, it is best used on small and medium size gardens, especially the latter, with the wide cutting deck making quick work of most average UK lawns (250-300m2).

Runtimes do vary depending on conditions though, so if the grass is long or wet it may have slightly less time. That said, the powerful motor and sharp blade do work well in less ideal mowing conditions.

As always, you can increase the runtime by buying a second battery, which essentially doubles the runtime to an hour. This is a good choice if your lawn is on the larger side or tends to get overgrown, with the second battery giving the extra time needed to finish those tougher tasks.

One of the best aspects of the battery is how quickly it charges. Fully charging in under 45 minutes, there are few cordless mower batteries that charge as fast as this, meaning you will not be waiting around long to recharge.

For example, some batteries take up to two hours to fully charge, so it is no exaggeration to call this one of the best batteries for a cordless mower.

Another thing to note is that this battery is interchangeable with other Greenworks tools – great for anyone that already owns some or are thinking of buying more electric cordless tools.

Cutting Width

The Greenworks 40 cordless mower is fitted with a 35cm steel blade. This blade is a good size for medium lawns, taking fewer passes to finish mowing compared to shorter blades, while it’s also suitable for smaller lawns and some larger lawns (although you may want a second battery for large areas).

There is a short gap between the blade and the deck, allowing closer cuts along edges, so if you have flower beds or borders around the lawn this a good feature to use. As with any good mower blade, it is made from hardened steel so incredibly durable, with the only maintenance needed being the occasional sharpening.

More importantly, this blade produces a clean cut across the grass leaf, ensuring a pristine finish that looks great and encourages healthier regrowth.

Cutting Heights

You always want to have at least three cutting heights on a lawn mower, as this allows you to remove the appropriate length of grass in any condition. Sometimes you want a close cut, like during growing season, while leaving grass longer is recommended during the cooler periods of the year.

So, the fact that the mower offers five cutting heights is great for gardeners that love a well-maintained lawn. Ranging from 20mm to 70mm, the five height settings let you remove the correct length of grass in all situations, whether it is a short length for the first cut of the season or removing lots of from an overgrown lawn. 

The 80mm setting is a good option for low-maintenance gardeners, as you can just remove a short amount from the top if you tend to let grass grow longer. This ensures the lawn looks tidy but remains healthy with minimal effort.

Adjusting the blade is also easy – just pull the lever at the side of the cutting deck to raise or lower it.

Usability

You never want a lawn mower that is difficult to operate, so making sure it is not too heavy is a good place to start. The mower is certainly not the heaviest, especially for mowers designed for medium lawns, weighing only 13.7kg.

It is easy to push and pull around the lawn, helped by the large and robust wheels that make improve manoeuvrability across most terrains. There are also padded handles to reduce vibrations when you mow, helping to fatigue in the hands when using for longer periods.

Also, the handle can be adjusted to a few positions to suit your height, helping to avoid unnatural positions that can cause back pains and aches. The power button is found on the right side of the handle, so left-handed people may find it trickier to hold for long periods, although this doesn’t require too much effort.

2-in-1 Functionality

A great feature of the lawn mower is being able to mulch grass clippings. While the mower can gather the clippings in the 40L grass collector for disposable, it also has a mulching function where the blade shreds the clippings into fine material before dispersing back into the lawn.

This not only saves the hassle of emptying the clippings, it also encourages a healthier lawn by redistributing organic material into the soil. These break down over time and provide the grass roots with added nutrients, resulting in healthier, more vibrant lawns free from weeds. 

Pros

  • Suitable for small and medium gardens up to 300m2
  • Takes under 45 minutes to fully charge the battery
  • Mulching function encourages an even healthier lawn
  • Good size cutting width for medium lawns
  • Battery works with other Greenworks tools

Cons

  • Does not include a rear roller so cannot produce a stripped lawn effect
