Regarding lawn mowers, wet conditions can wreak havoc on their performance and longevity. From riding mowers to push mowers, sensitive parts and areas of the mower can be permanently damaged if exposed to excess water. While some mowers may be water-resistant to a certain extent, having a wet lawn mower is generally not recommended, as it can lead to various issues.
If you’ve left your gas lawn mower in the rain or mowed wet grass, it’s essential to take steps to dry out your wet lawn mower as soon as possible. Start by wiping down the riding mower with a dry cloth and removing any excess grass clippings or debris. Check the oil level and filter for any signs of water contamination, like a milky appearance. If you find water in the oil, drain it and replace it with fresh oil.
Next, check the spark plug and clean it with a wire brush if necessary. If the spark plug is damaged or corroded, replace it with a new one. Check the gas tank for any water or debris and drain it if necessary. Refill the gas tank with fresh gas and add a fuel stabilizer to help prevent any remaining moisture from causing issues with the fuel system.

How Lawn Mowers Work
If you’re using a riding mower or a conventional mower, it’s crucial to understand how they work.
Lawnmowers come in two main types: electric and gas-powered.
- Gas-powered lawn mowers work by using a combustion engine to create power. This gas engine requires fuel, air, and a spark to ignite the fuel and generate the energy that powers the blades.
- On the other hand, electric lawnmowers use a motor powered by electricity. This motor spins the blades and cuts the grass.
Regardless of your lawn mower type, there are sensitive parts and areas you need to be aware of. The spark plug is one of the most sensitive on your lawn mower; rain can quickly stop these from working. To help lawn mower to get going, plugs ignite the fuel and start the engine. If you allow your mower to get wet, the engine may not start or run poorly. It can be best to fit a new spark plug instead of trying to fix the one you have.
When a lawn mower gets wet, it can wreak havoc on sensitive parts and areas. Water can enter the fuel tank, system, oil tank, and electrical components. This can cause the engine to run poorly or not start at all. If you get your lawn mower wet, you can do a few things to help minimize the damage.
First, remove the spark plug and use a wire brush to remove excess water or moisture. Then, turn the lawn mower on its side and let it air dry for a little while. You can also use a clean container to drain moisture from your riding mower’s fuel tank, oil tank, or fuel system.

When dealing with a lawn mower, avoid mowing wet grass and clean the mower deck and blades after use to prevent grass clippings from trapping moisture. Also, use a wire brush to remove rust or corrosion on metal parts, like the wheel bearings. If you have a push mower, you can quickly clean and dry it yourself. Wipe down the push handle and let the whole mower sit and air dry before storing it.

How to Protect Your Lawn Mower from Getting Wet
Wet conditions can wreak havoc on your lawn mower, causing damage to sensitive parts and areas. However, there are steps you can take to protect your mower from getting wet, ensuring optimal performance and longevity.
