As the days get shorter and the temperatures start to drop, it’s time to think about putting your lawn mower into hibernation. Proper winter lawn mower storage can help extend the lifespan of your mower and ensure it’s ready to go next spring. Here’s a step-by-step guide on how to store your lawn mower for winter.
 1. Clean the Mower Thoroughly
Start by giving your lawn mower a good cleaning. Remove any clippings, dirt, and debris from the mower deck, blades, and other areas. You can use a hose or a scraper to get rid of buildup, but be sure not to spray the engine directly. Cleaning your mower prevents rust and keeps parts from degrading over the winter. Remember to also check and clean the air filter if needed, as a dirty air filter can impact the mower’s performance.
2. Empty or Stabilize the Fuel Tank
Gasoline can go bad and cause damage if left sitting for an extended period. You have two options here: either empty the fuel tank entirely or add a fuel stabilizer. If you decide to empty it, run the mower until all the fuel is gone. This will ensure that the gas lines, carburetor, and gas cap are all empty and won’t cause issues later. Alternatively, adding a fuel stabilizer can keep the gas from breaking down, protecting the engine’s fuel system. If you’re using a stabilizer, make sure to run the engine for a few minutes to circulate the treated gas through the fuel lines.
When emptying the fuel, make sure to do so safely. Consider using a gas siphon to remove the remaining gasoline and dispose of it properly. You can take any leftover gas to a local gas station for proper disposal or use it in other small engines if possible.
3. Change the Oil
Before storing, it’s a good idea to change the oil. Old oil can contain contaminants that can damage the engine over time. Drain the old oil and replace it with fresh oil to keep the internal parts well-protected during the colder months. Changing the lawn mower oil before winter storage helps maintain engine health. Don’t forget to properly dispose of the used oil at a recycling center or a gas station that accepts old oil.
4. Remove or Disconnect the Battery
If your lawn mower is battery-operated, remove the battery and store it in a cool, dry place. This prevents the battery from draining or becoming damaged due to extreme temperatures. For mowers with a lead-acid battery, consider connecting it to a trickle charger to keep it in good condition. Make sure the battery terminals are clean and free of corrosion before storage.
5. Sharpen or Replace the Blades
Winter is the perfect time to sharpen or replace your lawn mower blades. A sharp blade makes for a cleaner cut and a healthier lawn. Carefully remove the blade, sharpen it using a file or bench grinder, and store it in a safe place. If the blade is damaged beyond repair, consider replacing it so you’re ready for the next mowing season. Properly sharpened blades also reduce the gas task, making your mower more fuel-efficient.
6. Lubricate Moving Parts
To prevent rust and keep everything in working order, lubricate all moving parts. This includes cables, wheels, and any exposed metal components. A light coating of oil or a silicone spray works well for protecting these areas. Proper lawn mower maintenance includes lubricating parts to prevent corrosion, particularly around the gas cap and fuel lines, which can become brittle over time.
7. Store in a Dry Place
Lastly, store your lawn mower in a dry, sheltered location, such as a garage or shed. Cover it with a protective tarp to keep dust and moisture away. Keeping it out of the elements is essential to prevent rust and damage during winter storage. If possible, elevate the mower slightly to keep it off the ground and away from potential moisture. Ensuring that the gas tank is empty also helps prevent any fuel-related issues when starting it again in the spring.

8. Consider Using a Self Storage Facility
If you don’t have adequate space at home, using a self storage facility can be an excellent solution for storing your lawn mower during the winter months. Self storage units provide a dry, secure environment that protects your mower from harsh weather conditions, pests, and potential damage. Climate-controlled storage units are especially beneficial, as they maintain stable temperatures and humidity levels, ensuring your mower and other seasonal equipment are well-protected from extreme weather changes. This option is particularly useful if you have multiple pieces of equipment that need to be stored safely.
Bonus Tip: Check for Needed Repairs
Winter is a great time to inspect your lawn mower for any issues that might need fixing. Whether it’s replacing a worn-out spark plug, fixing a loose belt, or checking the air filter, addressing these problems now can save you time and hassle when the grass starts growing again. Conducting lawn mower repair during the off-season keeps your equipment in peak condition. Also, inspect the fuel lines for any cracks or signs of wear, as damaged fuel lines can lead to leaks and affect mower performance.
By following these steps, you can ensure your lawn mower stays in top condition and is ready to tackle your lawn as soon as spring arrives.
