Winter Mower Storage Checklist
Well folks, it finally feels like fall. After a long stretch of hot, dry weather, the air has cooled and there’s a hint of rain in the forecast. This is the first week all year that really feels like the season has changed. Our lawns are slowing down, growth is tapering off, and it’s about time we start thinking about putting up our equipment for the winter.
Proper winter storage isn’t just about parking your mower it’s about protecting your investment so it’s ready to fire up come spring. A few hours of care now can save you hundreds of dollars in repairs later. Follow these easy steps from BES-TEX Supply to keep both four-cycle and two-cycle engines in top shape through the off-season.
1. Clean the Mower Thoroughly
Remove all grass clippings, dirt, and debris from under the deck, around the engine, and on moving parts.
Why it matters: Moisture trapped under debris causes rust and corrosion—and can even invite pests.
How to do it: Scrape off buildup with a putty knife or scraper, then rinse with a hose. Let it dry completely before storing.
2. Take Care of the Fuel System
Old fuel is the most common cause of hard-starting engines come spring.
-
Drain or run out old gasoline completely.
-
Add 1 quart of VP 4-Cycle Fuel (2-year shelf life) and run the engine a few minutes to circulate it.
-
For two-cycle engines (like trimmers, blowers, and chainsaws), use VP SEF 2-Cycle Fuel pre-mixed and ethanol-free to protect carburetors and gaskets.
Why it matters: Stale fuel gums up carburetors and clogs jets. Stabilized fuel keeps the system clean and ready to fire up in spring.
3. Change the Oil (Four-Cycle Engines Only)
Drain old oil and refill with clean oil before storing.
Why it matters: Old oil contains acids that corrode internal parts. Fresh oil keeps everything lubricated and rust-free all winter.
4. Clean or Replace the Air Filter
Replace paper filters or wash foam filters with warm, soapy water and let them dry fully.
Why it matters: Good airflow means better combustion, easy starts, and more power.
5. Service the Spark Plug
Remove, inspect, and replace if needed. Spray a small shot of fogging oil into the cylinder and pull the starter cord once or twice before reinstalling.
Why it matters: Prevents rust on internal parts and ensures reliable ignition next season.
6. Sharpen and Oil the Blades
Sharpen dull or nicked blades and lightly coat them with oil to prevent rust.
Why it matters: Sharp blades protect your turf from tearing and disease while reducing engine strain.
7. Care for the Battery (If Equipped)
Disconnect and store indoors in a cool, dry place. Use a battery maintainer or trickle charger if available.
Why it matters: Batteries lose charge or freeze over winter, shortening their lifespan.
8. Check Tire Pressure
Inflate to the manufacturer’s recommended PSI.
Why it matters: Prevents flat spots and helps keep your mower level and balanced.
9. Inspect Belts and Cables
Look for cracks, fraying, or wear on belts, pulleys, and cables. Replace worn parts now.
Why it matters: A few minutes of maintenance now avoids costly downtime later.
10. Choose a Proper Storage Spot
Store indoors if possible in a garage, shed, or shop. If storing outside, elevate the mower and cover it securely with a quality tarp.
Why it matters: Moisture is the mower’s biggest enemy. Keep it dry to prevent rust and corrosion.
Bonus Tip for Two-Cycle Equipment
Before hanging up your trimmers, blowers, or chainsaws:
-
Empty the fuel tank or run it dry.
-
Add a few drops of mix oil into the spark-plug hole, pull the starter cord gently, and reinstall the plug.
-
Store equipment vertically or on racks to protect hoses and fuel lines.
Why it matters: Two-cycle engines rely on oil mixed with the fuel for lubrication, if left to dry out, they can seize or score the cylinder.
