The essential checklist for how to store a lawn mower
Before you tuck your machine away for the winter, you need to address the most critical component: the fuel system. Old gasoline is the number one enemy of small engines.
When fuel sits in the carburetor over several months, it breaks down and leaves behind a sticky, varnish-like residue. This gunk clogs delicate jets and prevents your mower from running smoothly when spring finally arrives.
Handling your fuel supply
You have two main options for managing fuel during storage. The first is to drain the fuel tank completely and run the engine until it dies, which removes all volatile liquids from the lines.
The second, and often more convenient method, is to fill the tank to the top and add a high-quality fuel stabilizer. This chemical additive prevents oxidation and keeps the gasoline fresh for up to twelve months.
Cleaning the cutting deck
Never store a machine with grass clippings caked under the deck. These clippings retain moisture, which promotes rust and corrosion on the metal housing.
Use a plastic scraper or a stiff brush to remove dried debris from the underside. If you use a hose, ensure the machine is completely dry before moving it into your shed or garage to prevent surface oxidation.
Mechanical maintenance before winter storage
A well-maintained mower is a reliable tool. While the engine is still warm from its final run, take a moment to perform a few quick mechanical checks that will save you time later.
Changing the oil and filter
Used motor oil contains acidic contaminants and combustion byproducts that can etch internal engine components over time. Draining the old oil now prevents these impurities from sitting in your engine block all winter.
Refill the crankcase with fresh, manufacturer-recommended oil. By doing this now, you ensure that the internal parts remain coated in clean lubricant, protecting them against moisture-induced corrosion.
Inspecting the blades
Examine your cutting blades for chips, cracks, or excessive dullness. A sharp blade is essential for a healthy lawn, as it cuts the grass cleanly rather than tearing it.
If the blades are damaged, remove them for sharpening or replacement while you have easy access. Always disconnect the spark plug wire before reaching near the blades to ensure the engine cannot accidentally turn over.
Choosing the right environment for storage
Even if your mower is perfectly cleaned and serviced, the environment where it sits can ruin your hard work. Avoid damp areas like dirt-floor sheds or unventilated spaces.
Moisture is the primary cause of electrical issues and rust. If you store your mower in a garage, try to keep it away from chemicals like fertilizers or pool salts, as these release corrosive vapors that can attack metal and rubber parts.
Using a protective cover
A breathable cover is a smart investment to keep dust and pests away from the engine. Avoid using heavy plastic tarps that trap condensation, as they can accelerate rust on the mower chassis.
If you lack indoor space, ensure the mower is parked on a concrete slab or a pallet to keep the wheels off the damp ground. Use a shed or a heavy-duty outdoor storage box designed for weather resistance.
Battery care for electric and push-button start models
If your mower features an electric start system, the battery requires specific attention. Lead-acid or lithium-ion batteries can lose their charge over time, especially in cold temperatures.
Remove the battery and store it in a cool, dry place inside your home or a climate-controlled workshop. Check the charge level periodically throughout the winter using a trickle charger to maintain battery health.
Frequently Asked Questions About how to store a lawn mower
Should I leave gas in the tank over winter?
Only if you use a high-quality fuel stabilizer. If you choose not to use a stabilizer, it is best to drain the tank completely to prevent the fuel from turning into a gummy substance that clogs the carburetor.
Is it safe to store my mower on its side?
Only if your owner’s manual specifically says it is safe. For most mowers, tilting them the wrong way can cause oil to leak into the air filter or carburetor, which will lead to a blue-smoke disaster the next time you start it.
How often should I check the mower during the off-season?
Once a month is plenty. Just take a quick look to ensure no rodents have moved into the air intake or nesting in the engine housing, as they can chew through wires and cause significant damage.
What is the most important step in winterizing a mower?
Fuel management. If you only have time for one task, treat the fuel or drain the system. It is the most common reason for service calls at repair shops every spring.
Final thoughts on seasonal equipment care
Taking an hour to prepare your equipment now pays dividends when the grass starts growing again. By following these steps, you avoid the common pitfalls of engine failure and costly professional repairs.
Treat your mower like the vital tool it is, and it will serve you faithfully for years. Keep your gear clean, your fluids fresh, and your storage space dry.
Stay safe out there, and enjoy the peace of mind that comes with knowing your equipment is ready for the next adventure in your yard. Whether you are prepping for spring or maintaining your gear for a long-term homesteading project, proactive care is the mark of a true outdoor enthusiast.
