How a Short Circuit Can Damage the MotorĪs short circuits often result in an excess amount of energy being routed to the wrong place in the electrical system, water exposure can result in significant damage to your lawnmower’s motor ( source). You’ll eventually need to do so as part of the repair process but you’ll have an opportunity to dry it off first. Then, a short circuit of the power occurs, which means that electricity is diverted from where it’s supposed to go within the mower.įortunately, if your lawnmower was simply left in the rain, there’s no risk of handling it unless you turn it on. These wires are insulated to protect against short circuits, but when they come into contact with a lot of water or repeated exposure to moisture, the insulation becomes ineffective.
The wiring that transfers electricity to the motor is usually made from copper and is wrapped around its center column. If the power interruption occurs while the lawnmower is in use, you can risk electrical issues and personal safety.Įlectric lawnmowers use electrical energy from its power source (the battery) to generate mechanical energy via the rotation of its motor ( source). That’s why it’s so important that you avoid mowing wet grass. Once water or moisture has accumulated on your motor, it can seriously undermine the intended function of its wiring and power delivery. How Water Damage Affects An Electric Mower’s Wiring

Your owner’s manual will have the most specific recommendations for your model.Ī good rule of thumb is to never mow the grass with an electric lawn mower if you can step on the grass and leave a footprint behind due to the wetness of the grass. If that’s not an option in your home, you can purchase a weather-resistent shed (link to Amazon) to store your lawnmower and other electrically-powered tools that would have the same problem.Īnother thing to keep in mind is the condition of the grass when you use your lawnmower. To best protect your electric lawn mower’s longevity, make sure to always store it in the garage to minimize the risk of condensation-related damage. As the temperature drops as night, water can easily condense on the underside of the water-resistance casings around the motor and battery. How Condensation Can Damage Your Electric M owerĮxposure to rain isn’t the only way that the elements can cause water damage to your electric lawnmower.Įven if you live in an area with little rainfall, widely fluctuating temperatures can result in similar issues. Make sure as soon as you realize your lawnmower has been caught in the rain that you start the drying process.
Gaps in connection can eventually allow water through that can damage the battery as well.īeyond just the damage water can do to the motor, excess moisture will also cause the battery connectors to corrode, which interrupts the energy supply from the battery to the mower’s motor.Īs a result, the lawnmower with either run with diminished power or may not turn on at all.
The battery casing is also made to be water-resistant, but, to allow the battery to be removed and replaced, the covering sits on a hinge that allows the compartment to be open. These openings also allow water to reach the lawnmower’s protected motor and wiring if it’s exposed to rain for long periods. Often, these cases are designed with vents that allow air to flow in and out, which helps keep the electric motor from overheating while in use. an electric mower isn’t, by any means, impervious to water damage from being left out in the rain. How Electric Lawn Mowers Are Designedīecause of its sensitivity to moisture, your lawnmower’s motor will be housed inside a water-resistant casing that’s likely made of plastic or metal.

If you act quickly, you can often prevent a rain-soaked electric lawn mower from being irreparably damaged, so you need to know how to dry it out correctly.
