Have you decided it’s time for an electric mower, but you can’t decide between corded and cordless?

Then you’ve found the right article. Because here we’re going to take an in-depth look at corded vs cordless lawn mowers – is a cord worth the hassle?

An electric mower is an excellent choice. It’s quiet, maintenance friendly and light. But do you need a cord or can you go fully mobile with a cordless version? In this article, we’ll look at the pros and cons of both types. We’ll discuss the things you need to think about before you make your choice, and we’ll help you decide which version is right for you.

In this, our definitive guide to corded vs cordless lawn mowers, we’ll discuss why your corded mower has a range limit of around 100 feet, we’ll do some quick math to estimate the size of lawn a cordless mower will cover on one charge, and we’ll tell you that corded mowers are significantly cheaper.

Why choose an electric mower?

First, why choose an electric mower at all? Isn’t the good ol’ gas powered mower the way to go?

Sometimes, yes. There are lawns that might benefit from a gas-powered mower, but for many people an electric mower is an excellent choice. Let’s break it down.

Advantages with an electric mower

  • Quieter – Without the engine of a gas-powered mower, an electric version makes a lot less noise.
  • Maintenance friendly – Again, because there is no engine to maintain, an electric mower requires less maintenance.
  • Light – The third advantage of not having that engine, your electric mower is much lighter. This makes it easier to push around your lawn.
  • Environmentally friendly – With no gas to burn, there are no fumes, no hazardous liquids, and no smell.

Disadvantages with an electric mower

The features of corded and cordless mowers

Now we’ve established the pros and cons of electric, it’s time to look at the differences and benefits of corded vs cordless mowers.



A corded electric mower has a range limit. You can’t just run a massively long extension cord (or connect two or more shorter ones together) and here’s why—electrical resistance. Electricity in your extension cord (and this is true for any electric cable) looses voltage the longer the cord. This means the 110v at your socket isn’t 110v when it gets to your mower.

Now for most lengths of extension cable (and therefore most lawns) this isn’t an issue. But once you get over 100 feet in length, the voltage drop on a normal domestic extension cord can cause your mower problems. You can overheat the motor, reduce the life of the mower, and in some cases it just won’t work.

If you’re using a domestic socket and need to use your mower over 100 feet away from it, you have three choices: get a cordless mower, get a gas-powered mower or get an extension cord with a larger than normal gauge wire.


With a cordless mower, you don’t have any issues with cable length. Obviously, you don’t have any issues with a cable at all. But what you have to be aware of is the time your mower will operate on a single charge.

They rate most cordless mowers to last between 1 and 1.5 hrs on a single charge. So how do you work out how much lawn you can cover? Time for some (very simplified) math.

First, take the cutting diameter of your mower. For our example, we’ll use 19 inches as this is a common blade diameter. This means our mower will cut a 19-inch strip. Now, take away a couple of inches because there is always overlap when you’re mowing (you never cut perfect 19-inch strips side by side on your lawn).

Next, we need to estimate the speed we mow and for the sake of our example we’ll make it easy and say a foot per second. So, with a 17-inch cutting width, we are cutting roughly 1.4 square feet per second. This means that we would cut around 5,000 sqf in an hour or 7500 sqf in 1.5 hours.

Obviously, there are several other factors to consider to get a more exact figure, but as a quick rule of thumb, you won’t be a million miles away. So, now you can work out if your mower will cut your lawn in one go.


A corded mower will always weigh a bit less than a cordless. Part of a cordless mower’s weight is the battery, so if you don’t need a battery, it will weigh less. And it follows: the bigger the battery (the longer you can run on one charge) the heavier the mower.

This can make a bit of a difference in how easy your mower is to operate around the lawn. Especially if you have a manually powered one. If your lawn is on a slope, it’s that bit harder to push uphill.

If you have a self-powered mower, this isn’t as much of an issue, but you will still need to lift and handle your mower occasionally, so the weight can still be a factor. A self-powered cordless mower means it needs to use some of the battery to power the wheels and not just the blades. This means that your mower will either be rated for less time on a single charge or have a bigger battery. But that comes at a price increase.

Ease of use

There’s no getting away from it. A cordless mower is easier to use. Without having to think about the cable, you can just keep mowing. Even with the added weight of the battery, a cordless mower is simplicity itself.

With a cable, you need to think about getting around obstacles, not getting tangled up, and you must avoid running it over. All this usually means you will flip the cord around regularly as you mow.


Electric mowers are very maintenance friendly. Aside from keeping them clean, you won’t have much to worry about.

The only difference here is in the charging of the battery. For the cordless mower, you must remember to keep your battery charged. You can get pretty frustrated when you set out to mow the lawn and realize you forgot to charge the battery from the last time.

Battery life & charge time

While we’re on the subject of batteries, it’s worth noting a couple of things. The first is that charging time can vary considerably between cordless mowers and will range from 30 minutes to two hours and above depending on the machine.

The next thing is, batteries deteriorate with charging cycles. After a few years, you’ll find that you’re not mowing as much before the battery needs charging.

One way to deal with both these problems, and we recommend it, is to buy a second battery. A second battery will make sure you don’t get almost finished and have to wait two hours to do the last little section. It will also help with the other charging issues.


There’s a big difference in purchase price between corded and cordless mowers. Modern batteries are high-tech, but that comes with a cost. A significant part of a cordless mower’s price is in the battery. And this is why a cordless mower can easily be twice the price of its equivalent corded version.


We’ve covered the advantages and disadvantages of corded and cordless mowers. We’ve looked at the major features of both and highlighted what you need to look out for. Now you should be ready to make your decision.

So, if you have a reasonable sized lawn, easy access to electricity sockets and want a lightweight cheaper machine, a corded option might be best. As long as you don’t mind that little extra awkwardness that comes with the cable, a corded mower will happily keep your lawn tidy for years. At a low price point.

If you want the freedom of not worrying about cables, or you need to mow over 100 feet from an electricity socket, then a cordless option is the right choice. But you will have to pay a premium for that freedom.

That’s it, it’s time to head to your sales point and take a look at the different models. But no matter corded or cordless, an electric mower is a good choice. Good luck with your mowing, and here’s to a soon to be tidy lawn!
