How to Store a Lawn Mower in the Garage: A Guide to Keeping It Running Smoothly?

The warm weather has finally arrived, and that means it’s time to fire up the lawn mower and get your green space looking its best. But what about when the leaves start to fall and the chill sets in? Proper storage is crucial for extending the life of your lawn mower and ensuring it’s ready to tackle next year’s grass. This article will guide you through the steps of storing your lawn mower in the garage, from prepping it for the off-season to maintaining its peak performance.

Storing a lawn mower in the garage is essential to protect it from the elements, prevent rust and corrosion, and ensure it starts smoothly when you need it next spring. By following a few simple steps, you can safeguard your investment and keep your lawn mower running like a well-oiled machine.

Prepping Your Lawn Mower for Storage

Before your mower goes into hibernation, it’s important to give it a thorough cleaning and prepare it for storage. This will prevent the accumulation of dirt, debris, and moisture, which can lead to corrosion and damage.

1. Give it a Good Clean

Start by cleaning the exterior of your lawn mower. Remove any grass clippings, dirt, and debris using a brush or a hose with a nozzle attachment. Pay particular attention to the underside of the deck, where grass clippings often accumulate.

2. Empty the Fuel Tank

Old fuel can gum up your engine and cause problems when you start it up next season. It’s best to empty the fuel tank completely. If you have a small amount of fuel left, you can add a fuel stabilizer to prevent it from degrading.

3. Change the Oil

Changing the oil is essential for keeping your lawn mower engine running smoothly. Refer to your owner’s manual for the specific oil type and quantity required. Drain the old oil and refill the crankcase with fresh oil.

4. Sharpen the Blades

Sharp blades cut cleanly and efficiently. Dull blades can rip and tear the grass, leaving a ragged and uneven finish. Sharpen your mower blades using a file or a specialized blade sharpener.

Storing Your Lawn Mower Safely

Now that your lawn mower is clean and prepped, you can begin storing it in your garage.

1. Choose the Right Location

Select a dry, well-ventilated area in your garage. Avoid areas that are prone to moisture or extreme temperature fluctuations. It’s ideal to find a spot that’s not directly exposed to sunlight or heat from appliances.

2. Store it Vertically or Horizontally

The best way to store your lawn mower depends on its type and your available space. For walk-behind mowers, storing it vertically by attaching it to a wall mount or using a specially designed stand can save space and prevent tipping. If you prefer horizontal storage, ensure the mower is stable on a flat surface.

3. Protect it with a Cover

A lawn mower cover will help keep it dust-free and protect it from moisture and potential damage. Choose a cover specifically designed for your type of lawn mower and ensure it fits snugly.

4. Protect the Battery (if applicable)

If your lawn mower uses a battery, you need to ensure it is stored properly to prevent damage. Disconnect the battery terminals and store it in a cool, dry place. If you have a rechargeable battery, charge it fully before storing it.

Maintaining Your Lawn Mower During Storage

While your lawn mower is safely tucked away, you can still take some simple steps to keep it in optimal condition:

1. Check the Tire Pressure

Low tire pressure can cause damage to the tire and affect the mower’s performance. Check the tire pressure every few months and inflate them as needed.

2. Inspect for Damage

Periodically inspect your lawn mower for any signs of damage or corrosion. If you notice any issues, address them immediately.

3. Keep it Clean and Dry

If you see any dust or debris on your mower, use a dry cloth to wipe it down. This will help prevent corrosion and keep it in good condition.

Getting Your Lawn Mower Ready for Spring

When spring arrives, it’s time to wake up your lawn mower and get it ready for another season of cutting. Here’s a quick checklist:

1. Charge the Battery

If your lawn mower uses a battery, charge it fully before starting it up.

2. Add Fresh Fuel

Fill the fuel tank with fresh, high-quality gasoline. Add a fuel stabilizer to help prevent the fuel from degrading.

3. Start the Engine

Start your lawn mower and allow it to run for a few minutes. This will help ensure everything is running smoothly.

4. Inspect and Adjust

Inspect your lawn mower for any loose parts or wear and tear. Adjust the blade height and make sure all of the safety features are functioning properly.


Storing your lawn mower properly in the garage is essential for keeping it in top condition and extending its lifespan. By following the tips outlined in this guide, you can ensure your lawn mower is ready to tackle next year’s grass with ease.


What are the essential steps for storing a lawn mower in the garage?

To effectively store your lawn mower in the garage, begin by cleaning it thoroughly. Remove any debris, grass clippings, or dirt from the mower deck and engine. Next, ensure the engine is cool and drain any remaining fuel to prevent stale gas issues. Lastly, sharpen the blades if needed, and consider adding a rust preventative oil to protect metal parts.

Finally, store the mower in a dry, well-ventilated area, preferably on a flat surface or a dedicated mower stand. This will help prevent damage to the mower and ensure it is ready for use next season.

How often should I drain the fuel from my lawn mower?

It is recommended to drain the fuel from your lawn mower at least once a year, preferably before storing it for the winter. This is because gasoline can break down over time and become stale, which can clog the fuel lines and carburetor.

If you are storing your lawn mower for an extended period, it is even more crucial to drain the fuel to prevent engine damage. By draining the fuel, you are ensuring that your mower is ready for use next season without any performance issues.

What kind of fuel should I use for my lawn mower?

For optimal performance and longevity of your lawn mower, it is best to use fresh, high-octane gasoline with an octane rating of 87 or higher. Avoid using gasoline that is more than 30 days old, as it can degrade and cause problems with the engine.

Additionally, using fuel stabilizers can help to extend the shelf life of gasoline and prevent it from going bad. Follow the manufacturer’s instructions for the correct dosage and application of fuel stabilizers.

Should I disconnect the spark plug before storing the lawn mower?

It is highly recommended to disconnect the spark plug before storing your lawn mower to prevent accidental starting. Disconnecting the spark plug ensures that the engine cannot be accidentally activated while in storage, preventing potential injuries or damage.

By taking this simple precaution, you can ensure the safety of your lawn mower and yourself. Always follow the manufacturer’s instructions for proper spark plug removal and reinstallation.

Should I cover my lawn mower while storing it in the garage?

Covering your lawn mower while storing it in the garage is highly recommended, especially in areas with high humidity or potential for dust accumulation. A suitable cover will protect your mower from dirt, moisture, and other elements that can cause damage over time.

When choosing a cover, ensure it is made of breathable material to prevent moisture buildup and mold growth. Regularly check the cover for any tears or damage to maintain its effectiveness.

What are some tips for keeping my lawn mower running smoothly?

To ensure your lawn mower runs smoothly, it’s essential to maintain it regularly. This includes tasks such as checking the oil level, changing the air filter, and sharpening the blades.

Follow the manufacturer’s recommended maintenance schedule for your specific mower model. By performing these routine maintenance tasks, you can extend the lifespan of your lawn mower and ensure it continues to operate at peak performance.

What are some signs that my lawn mower needs to be serviced?

Several signs indicate that your lawn mower might need servicing. If you notice any of the following, it’s a good idea to have your mower inspected by a qualified mechanic:

  • The engine starts but won’t run properly.
  • The mower smokes excessively or emits unusual noises.
  • The mower vibrates excessively or cuts unevenly.
  • The mower is losing power or stalls frequently.

Addressing these issues promptly can help prevent more significant problems and ensure your lawn mower continues to perform reliably.
