Things to Know Before Buying an Electric Lawn Mower
Whether you always pride yourself on your perfectly mown lawn, or you’ve decided that this is the year you’re finally going to start taking care of your garden, an electric lawn mower is certainly a worthwhile purchase.
Producing a fraction of the noise of a petrol lawn mower, and being lighter and easier to use, electric lawn mowers are perfectly suited to small- to medium-size gardens.
There are, as always, a lot of different models out there, and looking for the best electric lawn mower for your garden can leave you scratching your head in confusion. The following advice has been put together to help you make an informed decision:
You will likely be trying to decide whether an electric or petrol mower is the best way to go. Here are some pros and cons to both types to help you weigh them objectively.
Electric lawn mower
- Powerful enough to cut through nettles and weeds
- Has power-assisted movement
- Cordless (when battery powered)
- Battery-powered versions run out of charge
- Batteries need to be charged before job can be continued – charging will take over an hour
- Danger of cutting through cord (when mains powered)
Petrol lawn mower
- Extremely powerful – can tackle nearly all terrain
- Easy to re-fill (don’t need to wait to charge like battery-powered mower)
- Emits fumes
- Very noisy
- Heaviest option
A larger mowing width may help you get jobs done faster, but may not offer such good manoeuvrability.
From the products I reviewed, mowing width ranged from 36 – 45 cm. This is quite a big variation and is good to bear in mind when buying a new lawn mower.
For larger gardens without many obstacles to navigate, look for a wider cutting width to save time. You’ll be able to cover a larger area in fewer passes. However, the mower is likely to be a bit more cumbersome than slighter models.
If your garden is small with a lot of trees and flower beds to manoeuvre around, a smaller cutting width is more practical.
Most electric lawn mowers come with a range of cutting heights to choose from. The exact number of heights available, and their range, will depend on the machine you purchase. While some have 3 different heights to choose from, more advanced models can have up to 8.
If your garden is very overgrown, I recommend looking for a mower with a taller maximum cutting height. You’ll be better off cutting the grass on a higher setting first, then cutting it down shorter. If you try to go in too short too quickly, you’ll likely overwhelm your mower.
To get shorter grass looking pristine, a height of around 20 mm is perfect.
Electric mowers should be both comfortable and easy to use.
This is partly dictated by weight – a lightweight mower will be easier to take in and out of storage. Bear in mind that mowers are only power assisted when they’re switched on, so any other moving that needs to be done
You should also look for grippy, shock-absorbing handles. These will always make jobs feel less like hard work.
Another feature to look out for is an adjustable handle. If you can alter the handle height even taller or shorter family members will have no excuse not to mow! Jokes aside, an adjustable handle can really help avoid any back pain from mowing.
For easy storage, look for a mower with folding handles.
Electric lawn mowers that are cordless rely on battery power. As a result, the run and charge time is important; ideally you’ll want them to store enough juice to mow your entire garden in one go.
Most lawn mowers have a battery life of around 30 minutes. This will depend somewhat on a few factors. For example, if you’re trying to cut through thick weeds or nettles, or cut long grass short, the mower will have to work harder and the battery won’t last as long.
If you buy lawnmower from a company that has a range of interchangeable batteries between machines, you might find that you already have another tool in your possession that uses the same battery as your electric mower. This is great to look into, because in this case you can have batteries on charge whilst using the mower, and then switch them over.
Recharging lithium-ion batteries to full charge will likely take a couple of hours.
If you choose to purchase a hybrid machine, you’ll get the best of both worlds. These mowers can run on batteries, so can be used cordlessly where necessary, but can also use mains power.
Finally, take a look at the size of the collection bag. If your mower comes with a bag between 30 L and 50 L in size, you should be able to tackle most jobs without having to stop and empty it.
Alternatively, look for a mower with a mulching function which will shred the cuttings finely and redistribute them over the lawn, helping to fertilise it and retain moisture during the summer months. By using the mulching function you won’t fill up the collection-box, so you won’t need to stop to empty it.

Bosch Rotak 430 Cordless Electric Lawnmower Review
In my experience, this electric lawnmower was easy to put together and set up for the first time without any need for tools.
The build quality is good and the hardened steel blades are of excellent quality.
It’s light, weighing just 13.7 kg, so you don’t feel puffed after using it for some time.
Plus, the 36 V lithium-ion battery reaches 100% charge in 140 minutes, and 80 % charge in just over an hour. This is great news because you can get a small- to medium-sized lawn cut in one session, but it also doesn’t take long to charge if more juice is required.
In fact, if you have other Bosch products with transferrable batteries, you could even charge one up whilst using the other, and interchange them. The ultimate time saver!
The cutting width of this mower is 43 cm, again a good size for medium gardens, as well as large ones. It certainly decreases the workload when compared with smaller machines.
It gives a really good cut and feels pretty powerful as well. The cutting height is easy to adjust to a variety of settings, ranging from 20-70 mm. On the highest setting it will even cut through nettles and tough weeds with ease, making short work of my lawn even when the grass is damp.
It’s light, comfortable to use, and manoeuvres around obstacles with ease.
When I’ve used it, I find the batteries last for around 20 – 30 minutes depending on the length of the grass. The 50 L grass box means you don’t have to empty it too often either.
This mower is probably best suited to lawns up to 600 m².
Overall, I’ve found this to be a powerful mower that can tackle long grass and large lawns without problems. I definitely recommend it as the best electric lawn mower available because it’s just so easy to use and efficient.
Einhell Lithium Cordless Ion Electric Lawnmower Review
This is a well-built machine that seems durable and long lasting. It was easy to put together and came with decent instructions. The unit weighs 16.5 kgs making it light and easy to manoeuvre. The folding handle makes it easy to store.
The mower comes with two 18-volt Lithium-ion batteries and two chargers and these are interchangeable with other Einhell power x-change tools. The high-speed charger can recharge the batteries in 75 minutes. I found the batteries lasted for around 20 minutes each.
The machine gave a good cut and the 43cm cutting width would be okay for a small to medium garden. The cutting height is adjustable from 25-75mm at six different settings.
When cutting longer grass you need to start with a higher setting otherwise the machine cuts out. So, on a longer lawn, you may need to do a couple of runs to get the grass at the length you want it. However, if you cut the lawn regularly this isn’t a problem and as it is so quick and easy to use it’s no problem to cut the grass once a week. The 63-litre grass box does need emptying quite regularly.
This mower is recommended for lawns up to 600 square metres.
This is an excellent mower for smaller to medium sized gardens and offers great value for money.
Black & Decker Cordless Lithium-Ion Electric Lawnmower Review
This mower is easy to put together and has overall excellent build quality.
It weighs 20.5 kg giving it a solid feel, but is still light enough to be easy to use and have good manoeuvrability.
Black + Decker are renowned for their quality, and deliver 2 x 36 V Lithium ion batteries included with his mower. This gives plenty of power for larger lawns and a fast charging unit is included too; the batteries are ready to use again pretty quickly. They last about 35 minutes on average-length grass.
I found it best to cut long grass at a higher height setting first to save the battery and prevent it from cutting out. Then I went back over on a lower height.
This mower has a cutting width of 38 cm and 6 adjustable height settings. Height can be changed between 30 – 80 mm and is easily adjusted with a simple lever.
The grass collector has a capacity of 35 L which is pretty decent, although may need emptying when mowing larger lawns. There’s also an indicator to let you know when it’s getting too full.
Retractable handles make this mower easy to store, even in a small shed, and it’s suitable for lawns up to 600 m².
To wrap up, I would say this is a high-powered machine that is suitable for even large gardens; it can handle longer grass if cut on a higher height setting first, then a lower one.
Greenworks 40V Cordless Electric Lawnmower Review
This mower comes with 2 x 40 V batteries, plus a charger which can charge one battery at a time.
As mowers go, this one offers plenty of power, using both batteries at the same time. The build quality is great, and the cutting deck seems sturdy and means business.
The cutting width is 41 cm, and it has 5 cutting heights between 20 and 70 mm. The cutting blade is made of quality stainless steel and produced a good level cut even on dampish grass.
This mower is reasonably light, at just 17.1 kg, and easy to use. I found it offered excellent manoeuvrability and didn’t wear me out. Plus, the handle is easy to fold making is simple to store.
As well as mowing, this unit offers a mulching function. Incredibly useful if you like to mulch your lawn, feeding it and helping retain moisture. The mulcher chops the cuttings up into tiny pieces before redistributing them on the lawn.
If you choose to collect the cuttings instead, the 50 L grass box means you don’t have to do too many stops for emptying.
This mower is recommended for gardens up to 300 m² when used with the supplied batteries. You can also buy additional batteries, or interchange with those used in other tools in the “Greenworks 40 V” line.
This is a good value machine with plenty of features. It would be ideal for a medium-sized garden.
Ryobi 18V ONE+ Hybrid Fusion Electric Lawn Mower Review
This innovative hybrid mower comes with 2 x 18 V Lithium+ batteries AND can also also run off mains power. This is extremely useful as it gives a lot of flexibility.
You can use battery power for smaller more detailed areas and switch to mains for larger or more overgrown areas. Alternatively, use it cordless when further from a power source, and connect it up when closer.
When used with batteries I found they lasted quite a long time, so it would only be occasionally that the electric power would be required.
Plus, it’s nice to have the option of mains power to help cut longer, more overgrown grass at the beginning of the season.
The mower has a 36 cm cutting width making it slight enough to be easily manoeuvred around the garden, between flower beds, features and trees. There are also 5 different height options giving good flexibility.
It’s nice that this mower gives the option of either mulching or collecting the grass. The collection box is 45 L so the possibility to mulch can avoid having to stop to empty it.
This is a versatile machine which offers good value for money and is extremely useful considering the fact you can change between battery and mains power. I do feel this is one of the best electric lawn mower designs out there.
Electric Lawn Mower FAQs
Best practise is to remove the batteries after use and store them indoors. This way they will not be subjected to extremes of temperatures or damp, and they will last longer.
Lithium-ion batteries will last about 3 to 5 years before they need to be replaced. The exact amount of time will depend on usage and storage.
This depends on the quality of the construction, motor and batteries. In most cases, your electric lawn mower should last up to 10 years, although you may need to replace the battery after 5 years. Remember to store and maintain your lawn mower according to the manufacturer’s recommendations.
I highly recommend waiting for a dry day before mowing your lawn. Cutting wet grass can damage your lawn mower, whether it’s an electric mower or petrol powered model.
