How to Winterize Your Mower?

When mowing season winds down in Southern Maryland, it’s important to prepare your lawn mower for winter storage. Proper winterization not only protects your equipment from damage but also ensures it’s ready to run smoothly in the spring. Follow these simple steps to winterize your mower the right way.

1. Clean Your Mower Thoroughly

Before putting your mower away:

  • Remove grass clippings, dirt, and debris from the deck and blades.

  • Wash off mud and moisture to prevent rust.

  • Allow the mower to dry completely before storage.

2. Sharpen and Balance the Blades

Sharp blades make a clean cut, reduce strain on the engine, and protect your lawn from disease.

  • Blades should be sharpened every 20–25 hours of use.

  • Balancing ensures smooth operation and reduces wear on bearings.

  • At Southern Maryland Outdoor Power Equipment, we offer blade sharpening while you wait for just $9.58 per blade if you bring them in off the mower.

3. Use the Right Fuel (and Treat It!)

One of the most common winter storage mistakes is leaving untreated fuel in your mower.

  • Ethanol-based gas breaks down over time, causing gum deposits and clogged carburetors.

  • Always use a fuel stabilizer or switch to ethanol-free fuel before storage.

  • We recommend VP 4 Cycle Fuel — ethanol-free and formulated to extend engine life.

4. Change the Oil and Filters

Changing oil and air filters before storage prevents corrosion and keeps engines running strong.

  • Drain and replace engine oil.

  • Replace or clean the air filter.

  • Check spark plugs and replace if necessary.

5. Store Your Mower Properly

  • Keep the mower in a dry, covered area.

  • If possible, store it indoors away from moisture.

  • Disconnect the battery on riding mowers to prevent drain.

✅ Final Thoughts

Winterizing your mower is one of the smartest things you can do to protect your investment. From blade sharpening to fuel treatment and seasonal servicing, taking care of your mower now saves headaches (and costly repairs) in the spring.
