Winterize Your Zero-Turn Mower: Expert Tips for 2025

October 16, 2025

As the cooler months approach, it’s essential to give your zero-turn mower the care it deserves before storing it for the winter. Proper zero-turn mower winterization not only extends the lifespan of your mower but also ensures it performs at its best when the mowing season returns. In this guide, we’ll walk you through everything you need to prepare your mower for winter, from basic maintenance to advanced storage tips.

Why Winterizing Your Zero-Turn Mower Matters

Many homeowners and lawn care enthusiasts underestimate the importance of winter preparation. Without proper winterization, your mower can suffer from rust, fuel system issues, and battery failure. Winterizing a riding mower ensures that the engine, blades, and other critical components remain in top condition during the off-season. This prevents costly repairs and guarantees a smooth start next spring.

Step 1: Off-Season Mower Maintenance

Before storing your zero-turn mower, perform comprehensive off-season mower maintenance. This includes inspecting belts, checking tire pressure, and tightening loose bolts. Regular maintenance ensures that your mower is in excellent condition and prevents small issues from escalating during storage.

Step 2: Drain or Stabilize Fuel

Old fuel can gum up your mower’s engine and carburetor. To prevent this, either drain the fuel completely or add a fuel stabilizer for mowers. This helps maintain the fuel’s integrity and prevents engine problems during storage. Running the engine for a few minutes after adding a stabilizer ensures that it circulates throughout the system, protecting it fully.

Step 3: Change Oil and Check Fluids

Changing the oil before storage is a critical step in preparing your mower for winter. Old oil contains contaminants that can damage engine components if left over the off-season. Be sure to also check hydraulic and coolant levels, if applicable. For a detailed walkthrough, follow our guide on changing oil in zero-turn mower for winter.

Step 4: Clean and Protect the Mower

Proper cleaning is essential before storage. Remove grass clippings, dirt, and debris from the mower deck, blades, and undercarriage. This not only prevents rust but also ensures your mower starts clean next spring. Cleaning and storing zero-turn mowers for winter is easier when you follow a systematic approach:

Use a garden hose to remove dirt.
Apply a protective coating to metal surfaces.
Dry thoroughly to avoid moisture accumulation.

Step 5: Sharpen Blades Before Winter

Dull blades can lead to uneven cuts and increased wear on your mower. Sharpening mower blades before winter storage ensures that your mower is ready to deliver a clean cut as soon as spring arrives. Balanced and sharp blades also reduce vibration, protecting the engine and deck.

Step 6: Lubricate Moving Parts

Lubrication is key to preventing corrosion and keeping all moving parts in good condition. Use high-quality grease to lubricate the steering, wheel bearings, and deck spindles. Lubricating mower parts for cold storage ensures smooth operation when you bring your mower back into service.

Step 7: Battery Storage

Battery maintenance is another crucial step in zero-turn mower winterization. Remove the battery and store it in a cool, dry place. A trickle charger or battery maintainer can help keep the battery in optimal condition during the off-season. Proper battery storage for lawn mowers prevents power loss and extends the life of your battery.

Moisture is the enemy of metal. Store your mower in a dry, covered location. Apply anti-rust spray to exposed metal parts and consider using a breathable cover. Protecting mower from rust during winter ensures that your mower’s body, deck, and engine components remain intact until next season.
