Proper storage ensures your lawn equipment will run well for years.

September 26, 2023

Winter is on the horizon and it’s time to store your lawnmower and other lawn and garden equipment through the colder months. The following tips will help you maximize the life and performance of your lawnmower and ensure it springs quickly to life when you’re ready to mow grass again.

Stabilize the gas

Without a stabilizer gasoline can break down in as few as 30 days. Oxygen, humidity, heat and other factors cause gas to change over time. Varnish, gums and other debris may form, which can clog the tiny passages in fuel lines and injectors or stick the floats in carburetors, preventing the engine from starting in the spring.

AMSOIL Gasoline Stabilizer disrupts the chemical chain reaction that causes gas to oxidize and form varnish and gums. It keeps fuel fresh up to 12 months. As shown, it also fights corrosion and improves stability better than Sea Foam Motor Treatment*.

Clean or replace the spark plugs

The spark plugs in a well-maintained lawnmower should last for years. Even so, check the condition for excessive deposits or wear to the electrodes. Clean on a wire brush (bench grinder is what I use) or replace any dirty plugs as needed. While you’re at it, check the gaps and set them to the proper size, as indicated in the owner’s manual.

Fog Spray the engine

With the spark plug removed, spray fogging oil into the engine. It protects the cylinder, piston and valves from rust and dry-start-induced damage in the spring. Slowly pull the starter cord a few times to distribute the oil, then replace the plug.

Remove the battery

You know, people don’t maintain batteries like they used to.. To prevent frigid temperatures from freezing and ruining the battery, remove it and store it in a safe, climate-controlled environment. Avoid placing it next to your furnace, water heater or other mechanicals in the basement. Put it on a shelf away from open flames. Clean any deposits on the terminals.

Clean and protect the mower deck

Use compressed air, a putty knife, water and AMSOIL Heavy Duty Degreaser to remove grass clippings, leaves, dirt and other caked-on debris from the engine and mower deck. Don’t forget to clean the underside of the deck, too.

Let me tell you something, If you prefer to ease the pain of doing this dirty work again next year, try coating the underside of the mower with AMSOIL Mudslinger. It forms a durable armor against the accumulation of grass clippings, making cleanup easier.

Change the oil and filter

Too many people let the mower go another year without changing the oil.. Don’t do that! Used oil contains acids that can slowly rust or corrode metal components. Once rust or corrosion start, they don’t stop. Contaminants can flake off and populate the oil. When the engine is running, they scour like sandpaper and wear out metal parts. Prior to storage, change the oil to remove acidic byproducts and ensure maximum protection against rust and corrosion throughout the winter.

Clean or change the air filter

A steady supply of clean air is just as important to engine operation and performance as high-quality fuel. Grass clippings, leaves, dirt and other contaminants can clog the air filter, causing the engine to start hard or run poorly.

Direct compressed air from the inside of the filter toward its outside to remove contaminants prior to storage. If it’s excessively dirty, replacing it is cheap insurance. The air filter is the only line of defense keeping contaminants from entering the intake and wearing out the cylinder and piston rings. It’s far less expensive to replace an air filter than an engine. Heck I always vacuum mine and it lasts for years. I used to buy them cheap at Kmart. Wish we still had our Kmart around..

Sharpen the blades

This isn’t required before lawnmower storage, but it’s more convenient to do it now, so nothing prevents a quick mow when that first sunny and dry spring day finally arrives. Remove the blades and sharpen them using an angle or bench grinder, but don’t hesitate to replace them if they’re in bad shape. I’ll tell you what, look for a good mower shop (dont tell him you use AMSOIL as he’ll know you never need repairs, lol) and see if they do blade sharpening. Proper sharpening in a jig makes a huge difference especially in a mulching mower.

Store in a dry, covered place

Once the mower is cleaned and prepared for storage, place it in a clean, dry place for the winter. Avoid storing it outside, but if you have no choice, secure a tarp over mechanical equipment to help protect sensitive components from the elements.

Following these simple lawnmower storage and maintenance tips will ensure your mower starts right up in the spring and continues to provide excellent service for many years.

How to Store a Snowblower

How to Store your Snowblower properly. Prevent damage during summer season.

Storing a snowblower properly is vital to ensuring it fires up when the snow eventually returns. When the first storm of the season dumps eight inches of snow on your driveway, you don’t want to be messing around in the garage when your snowblower won’t start.

fuel stabilizer is key for storing the damn snowblower

Time needed: 30 minutes.

Step-by-step: How to store a snowblower

Stabilize the gas
This is the most critical step to ensuring the snowblower starts right away in the winter.

Gasoline begins to break down in as few as 30 days. Varnish and gums begin to form, which clog the tiny fuel passages in the carburetor. I can tell you from experience that it doesn’t take much to clog a snowblower carburetor and prevent it from starting.

AMSOIL Gasoline Stabilizer keeps fuel fresh up to 12 months. As the image shows, it also does a great job fighting corrosion to keep metal fuel tanks and other components clean and working properly. After adding stabilizer, run the engine for a minute or two to distribute treated gas throughout the fuel system.
Change the oil
Running the engine to distribute gas stabilizer has the added benefit of warming the oil so it flows more easily.

Changing oil before you store your snowblower removes acids and other combustion by-products so they’re not sitting in the engine throughout the summer. Plus, the engine will be ready with fresh oil come winter.

Don’t cheap out on oil – you likely spent upward of $1,000 on your snowblower, so you want it to last. Plus, small engines are tougher on oil than most people think. They’re air-cooled, meaning they run hotter than automotive engines, typically don’t include an oil filter, further stressing the oil, and are often neglected.

AMSOIL Synthetic Small-Engine Oil is a commercial-grade formulation that fights wear and deposits in the toughest conditions. It also flows readily in the cold for maximum start-up protection.
Fog the engine
Simply remove the spark plug and apply fogging oil. It coats the cylinder wall and piston with oil to help prevent corrosion from forming during the summer. If corrosion forms, it flakes off into the oil and scours the bearings and other components, causing wear.
Check the gear lube
Remove the gearbox fill bolt and ensure the housing contains sufficient oil. Check your owner’s manual for the proper lubricant.
Inspect the belts
Now’s the time to check drive belts for cracks or abrasions. Replace them if needed.

Otherwise, I promise you they’ll break at the worst time, like at 5:30 a.m. on a cold November morning after a wet, heavy snowfall. Be proactive and save yourself a ton of grief down the road.
Check the linkages, auger housing and other areas
Before you store a snowblower, look it over from top to bottom. Check for damaged parts and linkages. Lubricate pivot points with a spray protectant, like AMSOIL MP. Spray the auger housing to guard against rust formation over the summer.

Don’t overlook this step. While examining my snowblower last year, I realized three of the four bolts that hold the auger housing and chute (sometimes called the “bucket”) to the chassis had sheared. One bolt was literally holding the snowblower together.

The following Thanksgiving weekend, two feet of snow blanketed Duluth, Minn. I spent eight hours moving snow. Imagine if I hadn’t repaired the snowblower the prior spring and that last bolt had given out halfway down my driveway?

Again, be proactive now to avoid a ton of problems later.
Store the snowblower inside
Finally, park your snowblower in the back of the garage or in a shed for the summer to protect it against rain. If you have no choice but to store it outside, cover it securely. I bought a nice cover at Kmart a few years ago and it still does the job.

Following these steps will help ensure your snowblower is ready to go the next winter.
