How to Store Lawn Mower Outside Without a Shed?

Homeowners get confused all about where to keep their lawnmowers since there is no space inside the house or garage. Some might not even have a garage. Most of them are left with the only option to keep it outside.

But then, a good homeowner would think of ways to keep the lawnmower safe and in good shape even if it is outside.

  • Use a lawnmower cover cloth or a tarpaulin:

This is one of my favourite go-to options. Although it might not be as good as having your lawnmower in a garage, it offers good protection, especially with tarpaulin.

When the lawnmower is covered properly with the cover cloth or tarpaulin, rain falls on the tarpaulin. The tarpaulin prevents the water from getting to the machine.

Lawn mower cover:

A lawn mower cover is a device that keeps your lawn mower safe from the factors by shielding it from rain, snow and debris. They can be made of a variety of materials, including canvas, vinyl or mesh. Some covers are designed to fit over the entire mower while others are designed to protect just the engine and wheels. Some also feature built-in handles.

They come in a variety of sizes and shapes and can be used for both residential and commercial use. We suggest the craftsman lawn mower cover(Amazon) it’s durable and effective to protect your lawn mower from rain, droppings of birds and all other weather conditions.

Whatever type of cover you choose, it should have a sturdy construction that is resistant to tears and wear so it will last longer than other types.

  • Keep it under your porch:

This could be an excellent choice if your porch is sufficiently sized to accommodate the mower. It’s ideal if the porch has side walls that can be closed to keep the wind and rain away. While not as secure as a shed, this alternative is still preferable to having nothing at all.

  • Trees:

Your trees can serve as quite a protection for your lawnmower. It reduces the amount of rain that might touch the lawnmower and reduce the impact of the sun. But before you use the lawnmower, clean off anything that might be on it and If the tree has sap coming out of it, you might want to change to another location.

Further things you need to keep in mind:

  • Pack up the wires, engine, and batteries:

For lawnmowers powered by electricity and battery, remove their cords and battery. Since the whole lawnmower cannot be kept inside the house, the cords and wires can and they are safer inside the house.

  • Add fuel stabilizer:

If you are using a gas-powered lawnmower, leaving the lawnmower unused for days could degrade the fuel. Fuel begins to degrade between two to three weeks.

And because degraded fuel can clog the engine, you should empty the tank of its fuel before storing it. If you do not want to empty it, you can add a fuel stabilizer to keep the fuel from degrading.

Although the chances that something might eventually not happen to the mower, no homeowner would want to gamble with that.

You do not only expose it to getting wet by only leaving it in the rain but also by using it immediately after a rainfall.

Can You Leave Lawn Mower Outside in the Rain?

Leaving this power tool in the rain exposes parts of it to getting damaged. Parts such as the spark plug, wheels, carburetor, deck, engine, and push handle. Although there is nothing to worry about when some of these parts get wet, there is a lot to worry about if the carburetor, spark plug or engine gets wet.

The chances of this happening are not high though because most lawnmowers come with protective covers and filters but if this happens, those parts have to be removed and spread out for a couple of hours to dry.

The wet parts are most likely to get dried but the only permanent effect is that they might start to rust. The blade of the lawnmower might get blunt due to the rust.

Do not forget the part of chemistry that talks about what happens when moisture comes in contact with electricity, for those using an electric lawnmower.

Can You Leave Your Lawn Mower Outside in the Sun?

You might be thinking that the sun has no liquid to destroy your lawnmower, that in fact, it dries liquid. Yeah right, it does but it has its share of lawnmower damages.

The winter season is cold and it comes with quite a handful of damage to tools not to mention power tools. Though it is not a perfect idea, you can still store your lawnmower outside.

For homeowners who are left with no other options than to store their lawnmower outside during winter, there are a couple of things you could do to keep winter damages away from your power tool.

The first thing to do is to cover it with a quality, heavy-duty tarpaulin. A tarpaulin is a cloth-like waterproof material that keeps water from coming in contact with whatever it is covering.

The tarpaulin might be protecting the power tool from moisture but this can only be effective if the tarp has no holes and the machine is covered properly.

Another thing is to build a lawn mower storage box. With just a few basic tools, a lawnmower lover will make a box big enough to contain the lawnmower. Also with the right texture of the paint, the box can be made waterproof, notwithstanding the material it is made of, be it wood or metal.

The last thing is to make sure that the lawnmower is far above the ground. This is so that it does not absorb moisture from the ground. It could be hung on the wall and the tip part covered with tarpaulin.
