Bosch Rotak 430 Cordless Electric Lawnmower Review
If you have a medium-size lawn, this Bosch Rotak 450 Cordless Lawnmower brings a good balance of size/power/battery life to proceedings.
In these kinds of smaller spaces, it can feel excessive to use a petrol mower, but if you’re going to go electric, you still need a decent machine that can actually keep up (otherwise, what’s the point?).
This mower runs off one 36 V 2.0 Ah battery, which lasts for around 20 – 30 minutes. Sure, this doesn’t sound like long, but it is enough time to watch an entire episode of Friends or Frasier, so it’s still pretty substantial… Plus, there’s no cord to hold you back, meaning movement can be fast and unrestricted.
The 16.5 kg weight doesn’t curb efficiency either, especially when working on flat surfaces. It’s not a self-propelled machine, but the wheels turn easily and the handles are ergonomic, so it’s generally pretty easy to use. Only on the corners can it be a bit awkward to manoeuvre and turn.
Although the limit of 20 – 30 minutes run time might still be off putting to some, the battery recharges quickly in as little as 40 minutes. Which is, I believe, conveniently just the right amount of time for a brief lunch break…
Also, handily, if you have any Bosch tools that use the same battery, you can transfer them into this mower, so you might not even need to stop at all.
In terms of cutting performance, the 43 cm cutting width makes it a good size for medium lawns – it can get through some narrower spaces, but generally covers ground quickly. The cutting height adjusts easily, and ranges from 20 – 70 mm.
On the highest setting it will even cut through nettles and tough weeds, so this mower does have quite a lot of force behind it.
Depending on how you like to cut your lawn, you might find that the minimum cutting height of 20 mm still leaves your grass a little long – but this is really down to personal preference.
The grass box, despite being a little tricky to fit together, has quite a generous 50 L capacity, so (after the initial minor headache with assembly) it’s a very convenient and functional size.
- The charge time is fairly quick - 45 minutes from flat to full
- Quiet to operate so it won’t disturb your neighbours
- The cutting height is easy to adjust with the simple press of a button
- Some users find manoeuvering this mower around awkward shaped gardens difficult
- One battery lasts around 20 minutes
- The grass box is tricky to assemble
- The lowest cutting height may still be a bit long for some gardens
- Shouldn't be used or left out in the rain
Einhell Lithium Cordless Ion Electric Lawnmower Review
If emptying the grass-collector several times during one mowing session is one of your biggest gripes, the Einhell GE-CM 43 has the biggest clippings box of all the mowers featured here. Instead of making numerous trips to the compost bin, you can complete bigger jobs with less interruptions.
It has a 65 L capacity, which is almost double the size of some models, and is actually still 10 L more than the model with the next-largest grass box. To put this into context – 10 L is the size of a medium fish tank, so there’s certainly quite a bit more space for clippings in this Einhell GE-CM 43.
When empty, it weighs 16.5 kg, and naturally gets heavier as it collects more grass; however, a mulching adaptor is also included, so you can also choose to jettison the clippings out onto the lawn, to create a natural fertiliser for the grass if you wish – keeping the weight of the mower down.
In addition to its relatively light weight, the mower moves easily and isn’t restricted by any power cables – it runs off 2 x 18 V batteries and they hold enough charge to get a good amount of mowing done. Depending on the length of your grass and your chosen cutting-height setting, it should be possible to mow a small/medium garden without running the batteries flat. They last for around 20 minutes.
There are six different cutting heights to choose between, adjustable from 25 – 75 mm. Whether you’re aiming to gradually reduce longer grass, or maintain a shorter lawn, this mower has enough scope to achieve either objective.
Tackling grass that is a lot taller than the maximum cutting height can cause the mower to stutter, as well as use a fair amount of battery power, so it’s generally better suited to use on lawns that are relatively frequently maintained.
With a 43 cm cutting width, mowing a small/medium lawn can be done pretty efficiently. This also helps get more from the batteries because it’s wide enough to allow more grass to be cut in less passes. If you have a lawn with smaller, narrower areas, a 43 cm cutting width might be a little large, but it really depends on the space.
Two chargers are included, one for each battery, meaning that within approximately 75 minutes both batteries can be restored to full charge.
- A good option for those without much storage, this mower folds easily after use
- Offers good manoeuvrability so it’s suitable for awkward shaped gardens
- This mower is lightweight at 16.5 kg - so getting it in and out of storage is relatively easy
- Quiet to operate so won’t disturb your neighbours
- The handlebar adjustment makes it comfortable for a range of heights
- Struggles to cut longer grass
- While assembling the mower itself is simple, the collection box is tricky to put together
- The outer body is made from plastic which may not be as long lasting as metal
- The battery life may disappoint some people with larger lawns
Black & Decker Cordless Lithium-Ion Electric Lawnmower Review
The risk with big mowers is that they can be difficult to navigate around smaller parts of the garden; but then narrower mowers can take a long time to actually get the job done.
This Black & Decker Cordless Lithium-Ion Electric Lawnmower finds a good compromise between size and manoeuvrability, making it a good choice for small to medium gardens.
The 38 cm cutting width makes this mower easier to negotiate around flowerbeds, pathways, and awkwardly shaped lawns – I know we don’t all have perfectly rectangular gardens that can be whizzed up and down in a matter of minutes, so it’s nice to be able to get around obstacles easily.
It also has a longer cutting height available than other models, with 6 settings between 30 – 80 mm. As a result, this mower has less of a struggle tackling long, damp grass; it can be used on its highest setting and gradually worked down.
Although, it’s worth noting that 30 mm is the longest ‘lowest cutting height’ featured here, so if you’re after a very clipped lawn, ultimately this might not be the best electric lawn mower for you.
In terms of running time, this Black & Decker models stacks up very well against its competitors – it only uses one 36 V battery at a time, but comes with two provided, so one can be charged whilst the other is in use. The running time of one battery is around 30 minutes on a relatively well-kempt lawn (the battery will run down quicker on longer grass).
Ultimately, it’s quite possible to keep using this mower almost continuously by interchanging the batteries; however, they can sometimes get quite warm so need a bit of time to cool down between uses.
At 16.2 kg, it’s unlikely to be too heavy to move in and out of storage and it also stores away compactly, with a folding handle, so doesn’t take up much room.
The 35 L grass collector is a little on the small side, especially compared to other models on this list, but there is an indicator to let you know when it’s getting full.
Unfortunately, there’s no mulching feature, so it’s not really possible to mow without using the grass box, meaning it will have to be emptied relatively frequently.
- The lightweight 16.2 kg build makes it easy for most people to manoeuvre this mower in and out of storage
- The battery charges quickly, and the battery life is sufficient for most medium size lawns
- The compact design makes storing this mower in tight areas much easier
- The handlebar height is easy to adjust and accommodates many heights of user
- Performs well on long and even slightly damp grass
- The grass collector is made from plastic which is a little flimsy and difficult to construct
- The grass box level indicator is occasionally unreliable, in some cases allowing grass to escape when it gets too full
- The assembly instructions are lacking and not very informative.
- The batteries take a long time to cool down after use
- The shortest cutting height may still be too long for some gardens
Greenworks 40V Cordless Electric Lawnmower Review
Storage space in the garden is a valuable commodity, yet it can be pretty elusive. Finding tools that don’t take up the whole shed is a challenge, which is why it’s great to come across something like the Greenworks 40V Cordless Electric Lawnmower.
Whilst being a powerful mower in itself (we’ll get into performance shortly), it has the added benefit of folding up to be very compact; the handles completely collapse down over the body of the mower, creating a unit that takes up very little space.
It can run off one or two batteries, coming with 2 x 40 V batteries included. You can get a longer running time from either using both batteries together, or charging one of them on the provided charger whilst mowing with the other.
With the power of the mower cutting easily through the grass, and the manageable weight of 18.7 kg, it’s still easy enough to move the mower around the garden despite it not being self-propelled. This remains the case even if the garden is slightly sloped.
The cutting width of 41 cm is well sized for medium gardens, and there are 5 cutting heights available: from 20 – 70 mm. One downside seems to be that when the grass is cut on the lowest setting, it is still longer than you might expect – perhaps the cutting height is measured differently with this mower.
A mulching function is included, so if you don’t want to collect grass in the 50 L collection box, you can leave the clippings on the lawn as fertiliser.
In general, this mower works better to maintain a lawn rather than fight through very long, untamed grass. Harder tasks like this can cause the battery to run out pretty quickly; although, it’s worth mentioning that if you have any other tools in the ‘Greenworks 40 V’ line, the batteries are transferrable.
- At 18 kg, this mower is relatively lightweight
- Accommodates sloping terrain very easily
- It is easy to check how full the grass collection bag is - simply lift the plastic flap
- Quiet motor perfect for those living in residential areas
- The foldable design is suitable for those who lack storage
- May struggle with thick and long patches of grass
- One battery may only run for 20 - 25 minutes
- The user manual is not very informative and assembly is difficult
Ryobi 18V ONE+ Hybrid Fusion Electric Lawn Mower Review
What if I told you that there was an electric mower which could be cordless, but also never run out of power?
Well, like all things, it’s a bit more complicated than that, but the Ryobi 18V ONE+ Hybrid Fusion Mower does have the option to run on both mains and battery power. This means you can use batteries at the bottom of the garden, and then plug it in when you get closer to the house.
It’s like having the freedom of a cordless mower, but with the reassurance of mains-power.
The 2 x 18 V Lithium+ batteries last well when used on well-maintained lawns; when you switch over to mains power there is a marked difference in power so it can also cut longer grass. Making use of the available 5 different cutting heights can also help make cutting less taxing on the battery, and help extend running time.
With a 36 cm cutting width, this is a smaller mower which can be easily easily manoeuvred around the garden, between flower beds and trees. This is the narrowest model featured here, so it’s great for smaller spaces but will take a while to complete the job if used on a larger lawn.
It’s really best suited to small/medium lawns, a fact which is echoed by the size of the 45 L grass collector.
One thing to bear in mind is the weight, as, at 19.7 kg, it’s one of the heaviest electric mowers on this list – this is likely the compromise made for having a hybrid machine, so it’s a case of weighing up weight vs. convenience when considering this model.
- As a hybrid mower, you can switch to mains power when the battery dies
- Produces an even cut every time
- Simple to operate - starts with just push of two buttons
- Lever is easy to use to change between cutting heights
- The supplied mains cable is very short and will likely always need to be used with an extension
- The grass collection box is difficult to fit and smaller than many users expect
- This mower may be too heavy for some users, at just under 20 kg
- The wheels are fairly small and may struggle in longer or wet grass
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
- Cordless (when battery powered)
- No fumes – not harmful to inhale, nor as damaging to the environment
- No preparation required (petrol mowers may need petrol and oil to be mixed, or to be serviced before use)
- Battery-powered versions run out of charge, generally within 20 – 40 minutes
- Batteries need to be charged before job can be continued – charging often takes an hour or more
- When using a mains-powered mower, there’s a danger of cutting through cord
- Mains-powered mowers can restrict your movement and keep you tethered
Petrol lawn mower
- Extremely powerful – can tackle nearly all terrain
- If you run out of fuel, it’s quicker to refuel a petrol mower than wait for a battery-powered mower’s battery to recharge
- Emits fumes which can be harmful to inhale, and bad for the environment
- Noisy enough to often require the use of protective ear equipment
- Petrol models are often a lot heavier than electric machines due to their large motor, so they’re not easy to move in and out of storage
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.
Similarly, if you have a medium-large garden, but a lot of narrow areas, it’s better to go for a narrower mower. Having to do a few more passes is generally better than being forced to leave parts of the garden unmown because the machine won’t fit.
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, it’s recommended to look for a mower with a taller maximum cutting height (like 70 or 80 mm). 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. This can cause it to cut out, or result in the battery running down quickly (if it’s a battery-powered mower, of course!).
If you’re after very short, pristine-looking grass, a cutting height of around 20 mm is generally ideal. Most mowers go down to this height, but just keep an eye out as a few models have a minimum cutting height of 30 mm instead.
Electric mowers should be both comfortable and easy to use.
This is partly dictated by weight. For example, a lightweight mower will be easier to take in and out of storage. It will also be easier to push, if the mower isn’t power-assisted.
Checking the weight of the mower before purchasing it is vital – it’s better to go for something that you can move easily (and will therefore use often), even if it’s slightly less powerful, rather than something that will be very difficult to carry.
Other factors that improve comfort include grippy, shock-absorbing handles. These can also help reduce vibrations and make mowing for longer periods more pleasant.
An adjustable handle is another good feature to look out for. If you can alter the handle height, even taller or shorter members of the family will have no excuse not to help out with the mowing!
Jokes aside, an adjustable handle can really help avoid any back pain from mowing.
Still on the subject of handles, folding handles are a useful addition that make mowers infinitely easier to store. Having a more compact mower can make life easier by freeing up space in the shed.
Cordless electric lawn mowers 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.
If your mower comes with a collection bag above 50 L in size, you should be able to tackle most jobs without having to stop and empty it.
Larger bags (or boxes) mean less emptying, but they do make the mower heavier. Therefore, there’s a bit of a balance to made between grass-collector size and the weight that you’re willing to push around.
Alternatively, look for a mower with a mulching function which will shred the cuttings finely and redistribute them over the lawn. Mulch helps fertilise the lawn 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.
Not all mowers have a mulching feature, so you should specifically look out for this if it’s something that interests you.
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 3-5 years. Remember to store and maintain your lawn mower according to the manufacturer’s recommendations.
It’s recommended to wait 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.
In addition, damp grass puts a lot more strain on the engine of the mower, so it would have to work a lot harder to cut wet grass.
