Electric lawn mowers are a modern solution to traditional petrol powered lawn mowers, and these powerful machines are well-suited to working small and medium-sized gardens, keeping your lawn lush and neat.
In our Australian Buying Guide for 2021, we’re taking a look at the best electric lawn mowers on the market, as well as answering questions on how to choose the right model, maintain it and use your electric lawn mower safely.
Why Should You Buy an Electric Lawn Mower?
- Quiet operation – These lawn mowers are significantly quiet when compared to petrol lawn mowers, operating at about 75 decibels, which is approximately the same noise level as a normal conversation.
This protects your hearing and makes this chore a lot more enjoyable for you and your neighbours.
- Low maintenance – These machines are almost completely maintenance-free. Aside from cleaning it off after using it and replacing blades as needed, electric lawn mowers are hassle-free.
- Easy operation – There’s no need to buy, store or mix fuels, and you won’t run out of fuel either.
- Lightweight – As they don’t have that heavy motor and fuel tank, electric lawn mowers are smaller and lighter than petrol models. This makes them easy to transport and manoeuvre, making mowing the lawn fast and strain-free.
- Eco-friendly – These mowers emit no fumes or greenhouse gasses, and they don’t use fossil fuels, making them a great choice for homeowners conscious of climate change, pollution and their carbon footprint.
- Affordable – Using electricity is substantially cheaper than fuelling your petrol lawn mower, and you save even more down the line as you don’t need to pay for engine tune-ups/servicing, oil, spark plug and fuel filter replacements either.
The Different Types of Electric Lawn Mower
When you want to buy an electric lawn mower, you’ll have to choose between two types – corded and battery lawn mowers.
Corded electric lawn mowers
These mowers are continuously supplied with electricity via an electric cord that can plug into any outlet in your home. They are usually lighter and more affordable than battery lawn mowers.
You can extend the range of this mower easily for larger gardens by adding on a rated extension cord, but there is the hassle of dragging a cord behind you that can snag on bushes and landscaping.
Battery lawn mower
Also called a cordless lawn mower, battery lawn mowers solve the issue of having to drag a cord behind you, giving you complete freedom and full range when you are mowing.
They tend to be a bit heavier and a bit more expensive because of the batteries, and you will also have to charge and possibly recharge the battery when mowing.
You will also have to replace the batteries every 5 years or so as they lose their ability to hold a charge over time. Here are some tips on how to maintain your lawn mower batteries.
Which is Better – Corded Electric Lawn Mower or Cordless Mower?
Both mowers have their pros and cons, and it’s all about seeing what is right for you and your garden.
Pros of Corded Electric Lawn Mowers
- Lightweight and easy to manoeuvre
- Constant, unlimited power supply
- Lower cost
- Runs at full power all the time
Cons of Corded Electric Lawn Mowers:
- Range is limited by cord length
- Cord can get run over to tangled in plants and landscaping
Best Suited To:
The best corded electric lawn mowers are best suited to smaller to medium-sized gardens where the lawn can be covered by the range of the cord (or the cord plus an extension cord), where you have an easily accessible outlet, and where you need more power to cut through tall/thick grass.
Pros of Cordless Lawn Mowers:
- Unlimited range
- Increased mobility (don’t have to constantly watch out for a cord)
- Similar experience to using a petrol lawn mower
Cons of Cordless Lawn Mowers:
- Limited operating time depending on the battery capacity
- Heavier due to the weight of the battery
- Higher cost due to the batteries
- Slightly more maintenance (charging the batteries, replacing them after their lifespan has run out
Best Suited To:
The best battery lawn mowers are well-suited to medium-sized gardens or gardens with more complex landscaping where cords can get damaged or tangled.
It’s also a good choice for people who are familiar with petrol lawn mowers and want a similar experience. If you do consider a battery lawn mower, try to get one that offers a spare battery so you can swap out easily while you work.
Remember, the higher the voltage on the battery, the more powerful the mower will be.
How to Maintain Your Electric Mower
Electric lawn mowers don’t need oil, spark plugs, air filters or petrol, but they do need a little maintenance to stay in perfect condition.
- Cleaning – Remove the battery and/or safety key and use a soft, damp cloth to remove any dirt and debris in the undercarriage and blade.
Wear protective gloves to prevent injury from the blade or use a blower/air compressor to blow out the debris. Do not use a pressure washer or lots of water, as this can force moisture into the motor and cause corrosion.
- Battery and cord – Check the battery and cord for wear and damage before you use your mower. There should be no exposed wires on your mower cord.
Always store your battery and mower in a dry location to extend the lifespan. With proper care, a battery should last 5 years.
How Long Do Electric Lawn Mowers Last?
This depends on the quality of the machine, as well as how you use and maintain it. Generally, you can expect an electric lawn mower to last 10 years with normal use.
The best battery lawn mowers will usually last around 5 years before you need to purchase replacement batteries.
Are Electric Lawn Mowers Reliable?
Yes, they are very reliable – especially when you buy a quality machine and maintain it well. Fortunately, electric mowers require very little maintenance! All you need to do is clean it after using it.
Is it Safe to Cut Wet Grass with an Electric Mower?
It’s best not to cut your grass when it is wet, regardless of what type of lawn mower you have. That’s because you can damage the lawn mower because of the additional strain that cutting through thick, bent over grass puts on the machine.
It will also clog up the lawn mower and won’t mulch well. Mowing wet grass can also damage your lawn, as the soft, slippery soil can cause the mower to sink in and rip out the roots of the grass.
An electric mower presents additional risks to you, as you risk electrical shock.
Are Electric Mowers Powerful Enough?
While they are not as powerful as petrol lawn mowers, both corded and battery lawn mowers have enough power to tackle any lawn with ease, even if the grass is thick and tall.
If you have a more challenging garden and want a cordless model, look for a machine with a higher voltage battery (around 80 volts) to deliver the most cutting power.
