Step-by-Step Guide to Winterizing Your Riding Mower
Let’s get your mower ready for its winter rest.
1. Clean Your Mower Thoroughly
Before you do anything else, a good cleaning is in order. This not only makes the mower look better but also helps prevent rust and corrosion.
Cleaning the Deck
- Disconnect the Spark Plug: Always disconnect the spark plug wire before cleaning to prevent accidental starts.
- Tilt the Mower: Most riding mowers can be safely tilted forward onto their rear wheels or backward onto their front wheels for easier access to the deck. Consult your owner’s manual for the correct way to tilt your specific model. Never tilt it so far that oil or fuel can enter the carburetor or muffler.
- Scrape and Brush: Use a putty knife or scraper to remove caked-on grass clippings and mud from the underside of the deck. A stiff brush can also be very effective.
- Hose it Down: Use a garden hose to rinse away loose debris. Avoid using a high-pressure washer directly on seals, bearings, or electrical components, as this can force water into sensitive areas.
- Dry Thoroughly: Allow the mower to air dry completely, or wipe it down with a clean rag. Pay special attention to crevices where water can pool.
Cleaning the Body and Engine
- Wipe Down: Use a damp cloth to wipe down the mower’s body, fenders, and seat.
- Clean the Engine: Gently wipe down the engine exterior to remove dust and debris. A soft brush can help get into cooling fins. Make sure the engine is cool before cleaning.
2. Change the Oil and Filter
Fresh oil is vital for engine health. Old oil contains contaminants that can damage the engine during storage.
- Warm Up the Engine: Run the mower for a few minutes to warm the oil. Warm oil flows better and carries away more contaminants.
- Locate the Drain Plug: Find the oil drain plug on the bottom of the engine. Place a drain pan underneath it.
- Remove the Drain Plug: Carefully loosen and remove the drain plug. Let all the old oil drain out.
- Replace the Drain Plug: Once drained, clean and re-insert the drain plug, tightening it securely.
- Remove the Oil Filter: Locate and remove the old oil filter. A filter wrench might be necessary.
- Prepare the New Filter: Lightly coat the rubber gasket of the new oil filter with fresh oil.
- Install the New Filter: Screw on the new oil filter until the gasket makes contact, then tighten it an additional 3/4 to one full turn by hand.
- Add Fresh Oil: Consult your owner’s manual for the correct type and amount of oil. Slowly add the fresh oil through the oil fill port.
- Check the Level: Use the dipstick to check the oil level. Do not overfill.
- Run the Engine Briefly: Start the engine and let it run for a minute or two. Check for leaks around the drain plug and filter. Turn off the engine, wait a few minutes, and check the oil level again, adding more if needed.
- Dispose of Old Oil: Properly dispose of the old oil and filter at a local recycling center or auto parts store.
3. Stabilize the Fuel
This is one of the most critical steps in winterizing a riding lawn mower. Old gasoline degrades and can cause significant starting problems.
- Add Fuel Stabilizer: Fill the fuel tank about three-quarters full with fresh gasoline. This reduces the amount of air in the tank, which minimizes condensation. Add a high-quality fuel stabilizer according to the product’s instructions.
- Run the Engine: Start the mower and let it run for about 5-10 minutes. This ensures the stabilized fuel circulates through the entire fuel system, including the carburetor and fuel lines. This step is crucial for fuel stabilizer lawn mower effectiveness.
- Alternative Method (Emptying the Tank): Some prefer to empty the fuel tank completely. If you choose this method, run the engine until it sputters and stops, ensuring all fuel is cleared from the carburetor. This is a more involved process and requires careful handling of gasoline.
4. Address the Battery
Proper battery maintenance riding mower ensures it’s ready for the next season.
- Clean the Terminals: Disconnect the battery cables (negative first, then positive). Clean the battery terminals and cable connectors with a wire brush or battery terminal cleaner to remove any corrosion.
- Charge the Battery: If you have a battery charger, give the battery a full charge before storing it.
- Storage Options:
- Leave it in the Mower: If storing in a cool, dry place, you can leave the battery connected but attach a trickle charger or battery maintainer. This keeps the battery charged without overcharging it.
- Remove the Battery: For colder climates or longer storage, it’s best to remove the battery. Store it in a clean, dry, non-metallic container in a cool place, away from extreme temperatures and direct sunlight. Recharge it periodically (every 1-2 months) if not using a maintainer.
5. Lubricate Moving Parts
Lubrication prevents rust and ensures smooth operation.
- Grease Fittings: Locate and grease all zerk fittings on the mower. These are usually found on wheel bearings, steering components, and mower deck spindle bearings.
- Lubricate Cables and Linkages: Apply a light coat of multi-purpose lubricant to control cables, linkages, and pivot points. This helps prevent them from seizing up.
- Inspect and Lubricate: Check the owner’s manual for specific lubrication points.
6. Mower Blade Sharpening
This is a great time for mower blade sharpening winter. Sharp blades cut grass cleanly, which is healthier for your lawn. Dull blades tear the grass, making it more susceptible to disease and browning.
- Remove the Blade: Disconnect the spark plug wire. Tilt the mower safely (consult your manual). Use a wrench to loosen and remove the blade bolt. Remember which side faces up.
- Sharpen the Blade: Use a file, grinding wheel, or bench grinder to sharpen the cutting edge. Maintain the original angle of the blade. A file is a good, accessible option for most homeowners.
- Balance the Blade: After sharpening, it’s important to balance the blade. Use a blade balancer to ensure it’s evenly weighted. An unbalanced blade can cause vibrations that damage the mower.
- Inspect for Damage: While the blade is off, check it for cracks, bends, or excessive wear. If damaged, replace it.
- Reinstall the Blade: Reattach the blade, making sure it’s installed correctly (the side that faces up should still face up). Tighten the bolt securely.
7. Address the Tires
Preventing flat spots is key for tire longevity.
- Inflate to Proper Pressure: Check your owner’s manual for the recommended tire pressure and inflate them accordingly.
- Elevate the Mower: For long-term storage, it’s ideal to elevate the mower so the tires are off the ground. You can use jack stands under the frame. This takes the weight off the tires and prevents flat spots from forming. If you can’t elevate it, place blocks of wood or thick cardboard under each tire.
- Reduce Tire Pressure: As an alternative to elevating, you can reduce the tire pressure slightly. This lessens the stress on the tire sidewalls. Remember to reinflate them to the correct pressure before using the mower next season.
8. Protect Against Rodents and Pests
Small critters can cause big problems in storage.
- Seal Entry Points: Mice and other rodents might nest in your mower’s engine or air intake. Stuffing steel wool or fine mesh into the exhaust pipe and air intake can help prevent them from entering. Be sure to remove these before starting the mower in spring!
- Cleanliness Helps: A clean mower with no leftover food scraps or oily residue is less attractive to pests.
9. Cover Your Mower
A good cover is essential for protecting the mower from cold and the elements.
- Use a Breathable Cover: A vinyl or heavy-duty fabric cover that breathes is best. This allows moisture to escape, preventing condensation and rust. Avoid tightly sealed plastic tarps, which can trap moisture.
- Secure the Cover: Make sure the cover is securely fastened to keep out wind, dust, and moisture.
10. Choose the Right Storage Location
The ideal storage spot is crucial for lawn mower winter storage.
- Indoors is Best: A garage, shed, or barn is ideal. This protects the mower from extreme weather, temperature fluctuations, and theft.
- Ventilation: Ensure the storage area has some ventilation to prevent moisture buildup.
- Avoid Damp Areas: Do not store the mower directly on a concrete floor if the area is prone to dampness. Placing a piece of plywood or a tarp underneath can help.
