Does It Hurt To Leave Lawnmower In Rain? [And Can a lawnmower be left outside?]

Yes, as long as the gasoline doesn’t have any water and the engine and controls on electric mowers are dry. However, keeping a mower dry is preferable. The design of most battery-powered mowers allows them to be able to shed rain and still perform well.

If you have a good gas-powered lawnmower from a renowned manufacturer, it will continue to work even if it is recurrently exposed to rain. Mowers made for the general public by lesser-known companies should still work.

Can a lawnmower be stored outside?

Protection against the elements and weather makes Lawnmowers suitable for outdoor use. So leaving a lawnmower outdoors for a short period is unlikely to damage it.

However, exposing the lawnmower to the weather for longer periods will allow it to wear out quicker.

And when it comes to keeping the lawnmower outdoors, we need to remember a few different storage factors, such as how long you will leaving the mower outside and the environment and environmental conditions.

Where should I store my lawnmower without a shed?

A shed is helpful so you can stack your gardening tools and other equipment inside, keeping them safe from the weather. But not everybody has a shed. You can store your small tools and appliances in your home or workshop. But what about larger equipment, such as a lawnmower?

When discussing outdoor storage, we must distinguish between short-term and long-term seasonal storage.

  • Short-Term or Routine Storage

If you store your lawnmower regularly or short-term, you can use it every one or two weeks. Ensuring the petrol is protected from deterioration, the engine lubricated, and the mower dry. You should use a protective cover or tarp to protect your mower from the elements when keeping it outdoors during the season. You may also store your lawnmower under an overhang or eave. You can also use a popup tent or a plastic garden storage box as temporary storage for your mower.

  • Storage for the Seasons or Long-Term

Take a few extra precautions to store your mower outdoors for the winter properly. 

If you’re using a gas-powered lawnmower, make sure to empty the tank. Remove and clean the mower’s spark plugs. This will help prevent accidental starts. Remove the blades and, if possible, stack them somewhere inside so they won’t get wet. Since the edges are incredibly sharp, wear protective gloves. Make sure to drain the oil tank as well if your mower has one.

Scrape off any mud or vegetation collected and trapped in the undercarriage. Be sure you don’t store your lawnmower in filthy conditions, as this will hasten the rusting process. It is best to avoid laying your mower on its side. This will help prevent petrol or oil leakage if you have any in the mower. Fill the petrol tank with new gas and the oil tank with new oil after washing your lawnmower. Also, enable the lawnmower to run for 5 to 10 minutes after adding the gas stabilizer.

What happens if you leave a lawnmower in the rain?

The core purpose of a lawnmower is outdoor gardening activities. However, since most machinery does not work well with water, we might have some worries.

If you forget to bring in your lawnmower after the afternoon shower, or you left your lawnmower outside after days of rain, wait till it dries out before starting it again. Moisture in the carburetor, air intake ports, or spark plug chamber of a lawnmower stops ignition, and the engine will not fire. Water could have polluted the lawnmower’s fuel and oil if left outside for an extended period, necessitating their replacement.

Water stuck inside a lawnmower will bring it to a complete halt. Waterlogging usually happens when lawnmowers are left outdoors, open to moisture, or when the caps are not screwed back on. Moisture is usually trapped in the gas tank and then fills the carburetor bowl. Water will also seep into the oil source, resulting in milky white oil. To restore a lawnmower to working order, fully drain any tank that could have been contaminated by moisture.

Can you wash a lawnmower with water?

To clean their lawnmowers, people will normally always use water. In such cases, the engine must be able to cool until cold water is applied. When it comes to lawn moisture, this would not be a choice if you plan to mow the grass. While hosing off your mower is appropriate, stop spraying water on the engine and never clean your mower with a pressure washer.

It is vital to clean after each use because decomposing grass can damage your mower’s metal parts.

You should, of course, clean your mower deck with soapy water and a garden hose. While your mower is weatherproof, it is not waterproof, so stay away from the engine.

Power washing is a fantastic method for cleaning the vehicle, decking, and driveway, but not the mower. The concern is that the pressure is so high that it forces water into bearings, wires, and underseals, where it rusts and causes failure and loss of money. The high-pressure water often washes away important assembly grease on axles, causing the dry parts to wear out prematurely.

Water on the electrics will cause them to malfunction, which can be costly and unlikely to be covered by the warranty. Water allows the wires, transmission, and belts to rust and ultimately connect and split, so avoid them.

Can Electric mowers get wet?

Electric lawnmower user manuals advise against using the mower in muddy or damp grass or during a rainstorm. Using any electric equipment in the rain is dangerous to the device and may result in severe personal injuries.

Electric lawnmowers produce mechanical energy from the spinning of their motor by using electrical energy from their power source, the tank. The wire that connects the engine to the power source is usually made of copper and wraps around the middle pole.

These wires are coated to prevent short circuits, but when they come into contact with a large amount of water or are exposed to moisture regularly, the insulation becomes inadequate. The power is short-circuited, ensuring the energy is redirected from where it is meant to go inside the mower.

Fortunately, if the lawnmower was left in the shower, there is no chance of controlling it until you turn it on. You’ll have to do so later as part of the repair operation, so you’ll have time to dry it off first. After allowing the mower to dry, detach the battery and clean the attachment terminals and all other electrical contacts with an electronic contact cleaner such as BW-100. You can decide to use grease or lubricant. You want to ensure that the ties are clean and free of moisture.

What is the best way to store a lawnmower?

Are you looking for a suitable location to store your lawnmower? One of the easiest ways to keep the lawnmower in good condition is to store it safely. Since a lawnmower is a more substantial investment, you’ll want to make sure it lasts, so you get your money’s worth! It is a hassle to deal with a damaged or malfunctioning lawnmower on a hot summer afternoon.

The right place to store your lawnmower would rely on several things, including the size of your yard, your budget, and the environment.


A popular place for lawnmower storage is the garage. It is an affordable place to store your lawnmower, especially if you have a house with an attached garage. However, buying a detached garage is more expensive. Garages, both attached and removed, are suitable for storing lawnmowers and other objects.

You probably get the best bang for your buck with a high-quality garage. However, many people use their garages for car storage or other purposes, and lawnmowers can take up a lot of space. Garages tend to get wet, so investing in a premium cover or constructing/purchasing a lawnmower storage unit can help keep it protected from the weather.


Lawnmowers may be kept outdoors after they have been used, but only with the proper treatment. When exposed to inclement weather, plastic can degrade, and metals can rust. However, this only occurs when they are left out in the open for a prolonged amount of time. Some homeowners like to leave their lawnmowers outside all year. If you have a stable lot or a big property that is unlikely to draw unwelcome visitors, leaving your lawnmower outside is an acceptable choice. The cheapest option is to store the lawnmower outdoors. However, you expose your lawnmower to the weather and vandalism, which means you can end up paying more in the long run for maintenance or even replacements. Not only that but parking your lawnmower outdoors can be cumbersome and even dangerous.

Tripping over a lawnmower will result in a serious injury. If you want to store the lawnmower outdoors, it is better to invest in a decent fabric tarp to hold bugs and rodents at bay while still protecting you and your family from sharp edges or tangled in the mower.

Storage Shed: A storage shed is an excellent place to keep your lawnmower out of the elements and out of the way of your precious garage or basement space. There are many storage sheds in different shapes and sizes for various applications and budget levels. When you use a well-constructed storage shed, you won’t have to worry about securing your mower because your belongings will be tucked safely away inside.

You won’t ever have to worry about repairing it. A wooden storage shed can be constructed to last for generations! Storage sheds are completely customizable. Racks, shelves, or a DIY garage storage unit can be conveniently installed inside the shed. Storage sheds, especially wooden sheds, require upkeep. A storage shed can be more costly at the beginning than any of the other options listed above, but you can get your money’s worth if you pick a high-quality shed from a trusted brand.

Plastic Lawnmower Box: At some large box shops, you will also find small plastic outdoor storage bins designed to hold lawnmowers. These storage bins are designed to house only a lawnmower and a few choice attachments, so they take up very little room. They are best suited to smaller lots in warm or cold climates. Plastic can stretch or warp in high conditions, risking damage to your lawnmower. Despite having some additional security, they are not difficult to breakthrough.

Basement: If you need to place your lawnmower for the season, put it in your basement. However, exercising extreme vigilance while storing your lawnmower inside your home would be beneficial. When you store your lawnmower in your basement with a loaded gas tank, toxic or even lethal gases are released into your house. Before parking the mower, make sure to clear the gas tank and run it outside. Of course, an automatic mower, which is safer to store indoors, would not have this issue. Keeping a lawnmower in your basement is not a recommended process, although it can be used in the short or long term if you have no other choice.

However, this is an option with a long-term strategy. If it’s winter and you want to store your lawnmower somewhere dry, you might bring it into your basement. This choice would not necessitate the use of a protective cover since the area is well-protected. Plumbing problems are the only danger to your lawnmower in your basement. If a pipe bursts without your knowledge, it may flood the area, affecting your blade as well.


There is no such thing as a fully waterproof lawnmower. Also, the most complex machines, such as lawnmowers, can be destroyed by vast amounts of water. When different products are advertised as waterproof, the makers almost always say ‘water safe.’ Lawnmowers will differ in terms of how affected they will be as a result of interaction with water. However, the majority of them are not waterproof. Lawnmower covers are specially made to shield lawnmowers from any major threat, including water and ultraviolet radiation. These covers are often sold individually, and in most situations, customers would need to buy them for individual lawnmowers.
