Can You Use A Battery Powered Lawn Mower On Wet Grass?

Most people think using a battery-powered lawn mower in wet or moist grass conditions isn’t practicable or advisable. The truth is, yes, it’s definitely possible to use them on damp grass or cutting wet grass with battery mower. However, it would help if you took some safety precautions to ensure that you don’t damage the machine. To know the reasons why it’s possible to do so and be equipped with the necessary precautions to keep away from damaging your lawnmower machine, keep reading.

It’s not advisable to use a battery-powered lawn mower in the rain. The battery will get wet and could short-circuit, potentially causing a fire. Wet grass can also clog the lawnmower’s blades, preventing it from cutting the grass properly. If the rain is not going to stop anytime soon, it would be best to wait until the rain stops before using your battery-powered lawnmower or get a gasoline-powered lawn mower instead.

Nonetheless, if you use your battery-powered lawnmower in wet conditions, keep it covered as much as possible and dry it off when you are finished using it. Furthermore, if something goes wrong, take it to a service center.

Is it bad for a lawnmower to cut wet grass?

It’s not bad for a lawnmower to cut wet grass, but it is bad for the blades and other parts of the lawnmower. Here are a few good reasons to avoid using electric mower on wet grass:

  • When it is raining or the ground is very wet from dew, you should not use your mower since the blades will get gummed up, and they may also damage the blade of your machine. Wet grass can stick to the blades and cause them to become dull more quickly. Letting some time pass before using a battery mower on wet grass will also reduce the risk that a blade damages your machine.
  • The grass blades are cut unevenly by one that is not dry. Wetness will cause air bubbles to form on the blade, leading to crazing in the finish of the mower.
  • The battery-powered lawn mower is not waterproof. If you try to cut the grass when wet, the water can get inside and damage the electrical parts of your machine. This might cause you some problems in the future.
  • There is a chance of rust forming on the metal parts of the machine. The moisture in the air and on the blades will cause these parts to start rusting. It is easy to clean a mower that has not been used on wet grass, but it is more difficult to clean one that has been used in this way. So, if you can avoid using your lawnmower on wet grass, you should do so.
  • Rain can make mowing the lawn more difficult, but it’s essential to remember that rain will also affect your safety. You may think nothing happens when you cut grass during a storm. But if any moisture is left on those wires (if you are using an electric mower), those droplets could cause insulation damage, leading directly to electrocution.
  • Mowing wet grass can lead to extra strain on your engine and shorten its lifespan.
  • If the blades are struggling to cut through taller grass, it can put extra strain on the motor and battery, which could lead to damage.

So, if you want to be on the safe side and avoid damaging your lawnmower, wait for the ground to dry before using it. Taking care of your lawn mower will make it last longer.

How to store the battery-powered lawn mower?

The most important way to extend the life of your battery-powered mower is to store it in a dry and ventilated place. If you have to keep it in a garage, ensure the door is open so that moisture and fumes can escape. Also, avoid storing your mower near gasoline cans or other flammable objects.

If you’re not going to be using your battery-powered lawnmower for an extended period, remove the battery and store it in a cool, dry place. Batteries can last longer if they’re not stored in extreme temperatures.

You can also clean your mower before you store it. Cleaning the blades and other parts will help them last longer. Read the manufacturer’s instructions for more specific tips to ensure a long life for your battery lawnmower.


Using a battery-powered lawn mower in wet conditions is possible if you maintain its safety procedures. Before each use of the mower, you should always check the battery. The lawnmower may not start or function correctly if the battery runs low. Moreover, if the battery is not strong enough to run the mower, you need to replace it inclusively for its battery model. In addition, make sure the blades on your lawn mower are sharp. A blade that is worn down makes the mower work harder, which can be harmful to the battery. Lastly, if your mower incurs a problem, you should make an immediate diagnosis for it or take it to an experienced mechanic.
