Battery-powered lawn mowers have seen a surge in popularity due to their quiet operation, ease of use, and eco-friendly features. However, like any other machine, they can develop problems, and one common issue is the mower cutting out unexpectedly. Let’s explore some common reasons for this issue and offer solutions to keep your lawn looking its best.

Low Battery Charge

The most straightforward cause for your battery lawn mower cutting out is a low battery charge. Battery-powered mowers depend on the energy stored in the battery to function. If the power supply dwindles, the mower might stop mid-job.

Before using your mower, ensure the battery is fully charged. If the battery doesn’t hold a charge well, or the charge quickly depletes during use, it might be nearing its end of life. Battery lifespan can vary greatly depending on usage and maintenance, but on average, you can expect to replace it every three to five years.

Battery Connection Issues

Another common culprit is an issue with the battery connections. If these connections are loose or corroded, the electrical flow will be inconsistent, causing your mower to cut out.

To resolve this, switch off the mower and remove the battery. Inspect the battery terminals for loose connections or signs of corrosion. Tighten any loose connections and clean any corrosion using a mix of baking soda and water. Ensure that the battery is dry and clean before reinstalling it.

Blade Obstruction

Something as simple as a blade obstruction can cause your battery lawn mower to stop working. Twigs, stones, or excessive grass clippings can jam the blade, causing an abrupt stop to protect the motor.

Before you investigate this, safety first – always ensure the mower is off and disconnected from the battery. Then, check the blade for any obstructions and remove them. It’s recommended to clean the underside of your mower after each use to prevent this issue.

Overloading the Mower

If you’re attempting to mow grass that’s too tall or thick, your mower might cut out due to overload. Most battery-powered lawn mowers are designed for maintaining lawns, not for tackling overgrown jungles!

If your grass is significantly tall, try setting your mower to a higher cutting level on the first pass, then lowering it for subsequent passes. This approach reduces the load on the mower and helps prolong its lifespan.

Faulty Switches

A battery lawn mower can also cut out due to a faulty safety or start switch. These switches are designed to ensure safe operation, but if they become faulty, they can prevent the mower from functioning correctly.

If your mower cuts out and none of the above issues seem to be the cause, you might need to replace the faulty switch. Most manufacturers offer replacement parts, and with a bit of patience, it’s often a job you can do yourself.

Faulty Motor

If all else fails, your battery lawn mower’s issue could be a more serious one, such as a faulty motor. This issue is less common and more complex to fix. If you suspect a motor problem, it’s advisable to reach out to a professional service technician or the manufacturer’s customer service for further assistance.


While battery lawn mowers are convenient and eco-friendly, they can present challenges when they cut out unexpectedly. By understanding the possible causes – low battery charge, connection issues, blade obstruction, overload, faulty switches, or a faulty motor – you’re better equipped to troubleshoot and rectify the issue.

Remember, consistent maintenance and following the manufacturer’s guidelines can prevent many of these issues. Here’s to a smoothly running mower and a perfectly manicured lawn!
