Commercial mowers are workhorses. Day in and day out during mowing season, they take on large lawns, commercial landscapes, parks, and everything in between. But when the mowing season winds down, and the temperatures drop, it’s time to think about how to properly store your equipment. The offseason is when your commercial mowers need attention the most—not on the job, but in the garage or storage unit.

Storing your mower the right way can mean the difference between starting strong next season or facing unexpected repairs, downtime, and expense. Here’s what you need to do to get your commercial mowers ready for a winter nap.

1. Clean Commercial Mowers Thoroughly

Before your tractor mower goes into storage, give it a full bath. Use a hose, scraper, or compressed air to remove all grass, mud, and debris from the deck, undercarriage, and engine area. Caked-on grass holds moisture and can lead to rust or corrosion. Pay special attention to hard-to-reach areas—buildup in these spots can cause mechanical issues over time.

Don’t forget the bagger, chute, and blades. Grass left sitting in these brush mower areas can rot and attract pests. It’s not just about appearances—clean equipment performs better and lasts longer.

2. Change the Oil and Filters

Old oil contains contaminants that can harm your engine during months of inactivity. Drain the oil and replace it with fresh, manufacturer-recommended oil. While you’re at it, replace the oil filter and fuel filter too. Starting the next season with clean oil and filters is a great way to avoid engine problems right out of the gate.

3. Drain or Stabilize the Fuel

Fuel left sitting in the tank can break down and gum up your engine and carburetor. You have two options: either drain the fuel tank completely or fill it and add a fuel stabilizer. If you use stabilizer, run the engine for a few minutes after adding it so the treated fuel cycles through the system.

Don’t overlook the fuel lines either—check for any cracks or wear and replace if needed.

4. Sharpen or Remove the Blades

Dull blades on a mower or brush hog won’t magically sharpen themselves over winter. Either sharpen them now or remove them and have them professionally sharpened before spring. Some owners even choose to store the mower without the blades to prevent accidental injury or damage. If you go that route, clearly mark the parts and store them in a safe, dry place.

5. Remove the Battery

If your mower has a battery, disconnect it and remove it for storage. Store the battery in a cool, dry place where it won’t freeze. Consider using a trickle charger or battery maintainer to keep it in good shape during the offseason. A dead battery come spring is a frustrating way to start the season.

6. Lubricate Moving Parts

Apply grease or lubricant to all moving parts, including wheel bearings, joints, and cables. This prevents rust and keeps everything operating smoothly. Follow the manufacturer’s guidelines for recommended lubricants and grease points.

7. Cover and Store Indoors if Possible

Ideally, your commercial mower should be stored indoors in a climate-controlled space. If that’s not an option, at least make sure it’s out of the elements. Use a heavy-duty mower cover to protect it from dust, moisture, and pests. Avoid using a plastic tarp alone—it can trap moisture and encourage rust.

If you’re using an outdoor shed or barn, make sure it’s ventilated and check periodically for rodent activity. Mice and other pests love to nest in engine compartments and wiring.

8. Perform a Quick Inspection

Finally, do a once-over inspection. Look for worn belts, cracked hoses, loose bolts, or anything that seems off. Making small repairs now saves time when the busy season hits again. Also, check tire pressure if your mower has air-filled tires—cold air can deflate them over time.

Bonus Tip: Keep a Maintenance Log

Use the offseason as an opportunity to document everything you’ve done. Write down oil changes, part replacements, blade sharpening, etc. Having a maintenance log helps you stay on schedule and can even boost resale value if you ever upgrade your equipment.
