Lawn Mower Garage Storage: How to Store It Safely Without Wasting Space

The best way to store a lawn mower in your garage is to push it to a designated corner or wall, fuel it down correctly before storing it for more than 30 days, and if space is tight, use a vertical mower lift or wall-mount storage system to get it off the floor. The specific approach depends on whether you have a push mower, a self-propelled mower, or a riding mower, since each one has different storage requirements and space demands.

This guide covers how to safely prepare your mower for storage, the best placement options in a typical garage, and a few storage products that make a real difference when space is limited.

Preparing Your Mower for Storage

Before you think about where to put the mower, you need to deal with the fuel. Gasoline that sits in a tank for more than 30 days starts to break down. It leaves gummy deposits in the carburetor that cause hard-start problems and rough running the following spring. This is the most common cause of mower repair calls after winter.

You have two options:

Option 1: Run the tank dry. With the mower running, close the fuel shutoff valve (if it has one) or let the engine run until it stalls from lack of fuel. This leaves the carburetor empty.

Option 2: Use a fuel stabilizer. Add STA-BIL or a similar stabilizer to the tank, run the mower for a few minutes so the stabilizer reaches the carburetor, then store it with a full tank. This approach is better for mowers you'll use again within 6 months.

For mowers stored more than 6 months, running the tank dry is cleaner.

Other Pre-Storage Steps

Beyond fuel, clean the underside of the deck with a putty knife or wire brush while the grass clippings are still fresh. Dried clippings trap moisture and accelerate rust. A quick blast with a garden hose works too, just let it dry completely before storing.

Remove the spark plug and add a tablespoon of oil to the cylinder, then reinstall the plug (don't reconnect the wire). This protects the cylinder walls from corrosion during long storage. It takes two minutes and extends engine life noticeably.

Storage Options for Push and Self-Propelled Mowers

A standard 21-inch push mower takes up about 20 by 24 inches of floor space when parked. That's manageable in a two-car garage but tight in a single-car setup.

Floor Storage Against the Wall

The simplest approach: push the mower into a corner or along the wall. Drawbacks are that it blocks other garage items and the mower sits where anyone walking past can bump into the handle.

Vertical Mower Lift (Wall-Mounted)

A vertical mower lift tilts the mower up against the wall, reducing its floor footprint from about 24 inches to 12 inches or less. The mower is suspended at an angle with the handle against the wall and the blade end resting on the floor. Some designs fully tilt the mower vertical with the nose up.

Look for lifts with a weight capacity of at least 100 pounds (most push mowers weigh 60 to 90 pounds), and make sure the model you buy fits your specific handle width. Handles vary from 18 to 22 inches wide at the grips.

A wall-mount vertical storage system can save you significant floor space and costs around $30 to $60 for a good lift bracket.

Mower Shed or Enclosure

A small plastic or steel shed next to the garage handles the mower without using any garage space at all. These run $200 to $500, require minimal assembly, and some municipalities count them as personal property that doesn't need a permit. Worth considering if your garage is already packed.

Storage for Riding Mowers and Zero-Turn Mowers

Riding mowers are a different challenge. A standard riding mower is 5 to 6 feet long, 3.5 to 4 feet wide, and can weigh 400 to 600 pounds. A zero-turn is similarly sized. Neither one gets stored vertically.

Dedicated Corner Allocation

Most people who have a riding mower simply allocate a corner of the garage to it year-round. If you have a two-car garage and only one car, the mower lives in the second car's spot. That works, but it means your other garage storage systems have to compensate for the lost floor space.

Storage Ramps and Platforms

Some homeowners build or buy a small platform with a ramp that raises the mower 6 to 8 inches off the floor. This makes oil changes easier (you can slide a drain pan under without crawling) and protects the undercarriage from moisture wicking up from concrete.

A 4x6-foot wooden platform built from 2x4s and plywood costs about $40 in materials and takes an afternoon to build. Riding mower lift platforms are also sold commercially for around $150 to $300.

Tractor Covers

For long-term storage in an unheated garage, a fitted tractor cover protects paint, seat material, and plastic components from UV degradation and dust. Measure your mower before buying a cover; universal covers often fit poorly and trap condensation underneath when the fit is too loose.

Maximizing Garage Space Around the Mower

The mower doesn't exist in isolation. How you organize everything else in the garage determines whether the mower feels like it fits or like it's always in the way.

Wall Storage for Lawn Care Accessories

The items that go with the mower (gas can, extra spark plugs, oil, blade replacement kit, charger for battery-powered models) can all go on the wall above or beside the mower's parking spot. A simple wall-mounted shelf at 60 inches height holds all of that without using floor space.

If you're organizing the full garage wall, the Best Garage Storage guide covers wall systems that work well alongside dedicated mower storage.

Overhead Storage for Seasonal Items

In the off-season, summer equipment like garden hoses, fertilizer spreaders, and lawn chairs can move to overhead ceiling racks, freeing up wall and floor space near the mower. Overhead storage platforms that bolt to ceiling joists hold 400 to 600 pounds and are perfect for seasonal rotation.

Battery Mower Storage Considerations

If you have a battery-powered mower (brands like EGO, Greenworks, or Ryobi), the storage approach is different.

Remove the battery before storing. Batteries left in the mower during storage can discharge fully, which shortens lithium-ion battery life. Remove the battery, charge it to 40 to 60% (not 100% for long-term storage), and store it inside the house where temperatures stay above freezing.

Cold temperatures significantly reduce lithium battery capacity. Storing the battery in a heated space through winter means you'll have full power again when spring arrives.

The mower body itself can stay in the garage without issues. The motor and electronics are sealed well enough to handle temperature swings.

FAQ

How much space does a lawn mower take up in the garage? A 21-inch push mower takes approximately 20 by 24 inches of floor space in normal parking position, or about 12 by 32 inches tilted vertically on a wall lift. A riding mower takes 50 to 70 square feet of floor space and doesn't have a good vertical storage option.

Is it safe to store a lawn mower in a garage with cars? Yes, as long as you store the mower with an empty tank or stabilized fuel. The main risk is gasoline fumes accumulating near ignition sources, so don't park a mower with old, untreated gas in a closed garage next to water heaters or other open-flame appliances.

Can I leave the mower outside under a cover instead of in the garage? You can, but it shortens the mower's lifespan. UV exposure degrades plastic components, moisture accelerates engine corrosion, and rodents are more likely to nest in an outdoor mower. If garage space is limited, a small shed is a better option than outdoor storage.

Do I need to change the oil before storing a mower? It's a good practice, especially for mowers stored more than 3 months. Old oil contains moisture and combustion byproducts that can corrode internal engine components. A fresh oil fill costs about $5 in oil and 10 minutes of work.

A Practical Storage Plan

The most effective setup I've seen in a typical two-car garage: mower parked in the back corner against the wall, wall-mount shelf at 60 inches directly above holding gas can, oil, and maintenance supplies, and a vertical bike hook or garden tool rack on the adjacent wall keeping long-handled items off the floor.

The mower doesn't block anything because it's tucked in a corner, and everything it needs is within reach on the wall above it. That's a more useful outcome than buying specialty storage furniture: assign dedicated corners and go vertical with everything that can go vertical.
