Can Electric Lawn Mowers Overheat? Find Out Here

Electric lawn mowers have made great strides in recent years. This has been driven by consumer demand, as more and more people are becoming aware of the environmental impacts of gas and petrol lawnmowers.

However, they do still have their downsides, and one of the most common complaints is that they can overheat. One way to avoid this is to pick a mower with a built in thermostat, which will automatically stop it once it gets too hot.

However, you will need to find one with a thermostat that is suitable for your lawn, and one that is suitable for the size of your garden.

Lawn Mowers and Overheating

Lawn mowers are an excellent way to give your lawn a professional look without breaking the bank. However, if you’re not careful, you can end up with a yard full of bald patches that take a while to recover. Overheating in your lawn mower can be caused by a number of different reasons.

In the past, when people wanted a great looking lawn, they turned to professionals. Today, with the price of lawn mowers at an all time low, it can be cheaper to buy your own lawn mower than to hire a professional, and you have the added bonus of pride of owning your own lawn mower.

However, one of the biggest problems people are facing with their lawn mowers is overheating. They are spending ridiculous amounts of money on repairs and maintenance, all because of this minor problem that is easily avoided. 

Troubleshooting Your Electric Lawn Mower

Most home gardeners have electric lawn mowers, and it's hard to imagine a day without them.

However, they can sometimes give us trouble, particularly when we don't take the time to properly care and maintain them. (We're busy people, and sometimes we just don't want to take the few extra minutes to do it right.)

The result is an mower that is more likely to break down, or that has to have its parts repaired or replaced.

Vents are Clogged

It's no secret that the electric mower is the choice of many homeowners, partly because of their relative ease of use.

But there are a few maintenance considerations you should be aware of if you want to keep your mower running smoothly and safely. Intake vents are a common problem area for clogs.

A build-up of debris, grass clippings, and other garden matter can block an intake vent, reducing airflow to the engine and causing it to overheat. Be sure to check the vents regularly and clear any blockages you find.

Motor is Failing

The mower's motor is failing and it overheats. This is a big problem because the engine shuts down causing you to stumble around in the dark trying to find the cord so you can plug the mower back up to finish the yard.

Whether you have a large yard or a small one, an electric lawn mower is the best choice for cutting grass. The size is perfect for a smaller lot, and the lack of an engine makes such mowers much quieter than gas-powered ones.

There are, however, a few common problems with these machines. One of the most common involves the motor burning out too quickly. This is especially common if the mower is used frequently without a break, or if the mowing height is too low.

Low oil level

Oil is an essential part of an electric mower, because it prevents friction and heat from destroying the mower's internal components.

An electric mower is also much safer than a gas-powered mower, because it's not going to blow up on the lawn. An electric lawn mower is not meant to be used without oil in the mower's engine.

If you are using a low oil level electric lawn mower and it starts to overheat, you have several options. You can stop mowing and allow the mower to cool off, you can use a different mower, or you can add more oil to the mower's engine.

Damaged cooling fins or shroud

All electric lawn mowers have cooling fins and electric shrouds. When the mower's shroud or cooling fins have been damaged, the electric mower's motor may overheat, causing it to stop running.

If the electric lawn mower is running, turn it off and let it cool for several minutes. If the damaged electric lawn mower will not turn on, there may be a blown fuse or the electrical cord may need to be tested for continuity.

If your lawn mower can not be started, it may be because the air flow through the engine has been restricted. This can happen when a blade becomes dull or if the fins on the mower's cooling shroud have been damaged by a foreign object.

The engine needs to be free of debris in order to operate properly. If the mower still can't be started after the engine is cleaned, it may be time to replace the head gasket; this is a common lawn mower repair.

Dirty lawn mower engine

You work hard to take care of your yard, so it makes sense that you want your tools to be in top shape, too. A lot of people don’t realize how important it is to keep their mowers in good shape.

Over the years, I’ve seen a lot of dirty lawn mower engine electric lawn mowers overheat. (Most of these were caused by a lack of maintenance.)

If you do not perform routine maintenance on your mower, you can cause problems—including overheating—that will damage your mower and even your yard.

Last Words

It's the height of summer, and you're probably looking for ways to cool off. One way to do that is to enjoy some time in your backyard, doing something that's good for you. You might enjoy gardening, grilling, or even sitting in the shade sipping a cool drink. But before you head out, ask yourself: Is your mower ready? If you haven't cleaned it out recently, you may be breathing in a lot more pollution than you realized.

My father, and his father before him, and his father; for the past 3 generations, my family have always been into gardening. The green fingers is a gift passed down to me and I thoroughly enjoy it! I also have worked in the manufacturing department for Bosch and DeWalt so I like to think I know a thing or two about tools and such!
