Can You Store a Lawn Mower in a Storage Unit?

Yes, you can store a lawn mower in a storage unit at Extra Space Storage. Smaller push mowers can fit in a 5x5 storage unit, while riding mowers may require more space. Drive-up storage units are especially convenient for moving lawn equipment in and out, but they aren't always necessary for smaller mowers.

How to Store a Push Mower vs. a Riding Mower

Push mowers are generally easier to store due to their smaller size and simpler design, typically fitting in compact 5x5 or 5x10 units—depending on whether you're storing other lawn equipment along with your mower.

Riding mowers need a larger storage unit, typically at least 10x10 or 10x15, to accommodate their dimensions and allow room to maneuver. Be sure to inflate tires before long-term storage to prevent flat spots.

How to Store a Gas Mower vs. an Electric Mower

Storing a lawn mower requires different preparations depending on its power source.

For gas-powered mower storage:

• Add a fuel stabilizer to prevent engine damage, or drain all fuel and run the engine briefly to clear remaining gas from the system.

• Change the oil, replace the air filter, and remove the spark plug for safety and machine longevity.

For electric mower storage:

• Remove the battery and clean battery terminals.

• Store the battery in a cool, dry place at around half charge—and check it periodically to prolong its lifespan.

For both gas and electric mowers:

• Thoroughly clean the mower of all grass clippings, dirt, and debris to prevent rust, corrosion, and pests.

• Lubricate moving parts like wheels and axles.

• Inspect and sharpen blades so they're ready for next season.

• Store upright in a cool, dry space.

Should I Use a Climate-Controlled Unit for a Lawn Mower?

A climate-controlled storage unit is the best option for long-term lawn mower storage, as it protects the mower from extreme temperature fluctuations and humidity that can cause rust, corrosion, and damage to plastic and rubber components.
