As winter approaches and your lawn needs less care, it’s time to give some attention to a hardworking hero in your yard: the lawn mower. Just like any piece of equipment, your mower needs a bit of TLC before it hibernates for the season. Properly winterizing it now means you’ll enjoy a longer-lasting machine that’s primed and ready to tackle the first cut of spring without a hitch. Plus, a few simple steps can save you from expensive repairs down the road. In this guide, we’ll cover all the must-do steps for winter mower prep, so you can stow it away confidently and keep it running like new for years to come. Let’s dive into everything you need to know for a smooth, hassle-free start next season!
1. Clean the Mower Thoroughly
Why It’s Important:
Grass clippings, dirt, and debris may seem harmless, but if they’re left on your mower over the winter, they can lead to a surprising number of issues. These residues trap moisture, which promotes rust, and can clog up the mower deck and blades, reducing efficiency when spring rolls around. Worse yet, dirt and grime buildup can impact the mower’s overall performance, leading to costly repairs or replacements. By giving your mower a thorough cleaning before winter, you’re not just removing dirt—you’re actively protecting every moving part, ensuring it’s ready for a fresh start come spring. In just a few easy steps, you can keep your mower running smoothly and extend its lifespan, making it a worthwhile task for every lawn care enthusiast.
How to Do It:
- Use a garden hose to wash off grass and dirt from the mower deck.
- Scrape off any hardened grass clippings.
- Dry the mower completely to prevent rusting.

2. Empty or Stabilize the Fuel Tank
Why It’s Important:
Old fuel left sitting in your mower’s tank can wreak havoc on its engine. As fuel ages, it begins to break down, forming sticky residues that can clog carburetors and lead to gumming, which can prevent your mower from starting when you need it most. Imagine looking forward to that first mow of spring, only to have your mower sputter and stall from months-old fuel buildup! Luckily, this is an easy fix: before storing your mower, either run it until the tank is empty or add a quality fuel stabilizer to preserve the fuel. This simple step helps protect your mower’s engine and ensures it’s ready to roar into action when you roll it out in the spring. Keep reading for more essential tips on winterizing your mower to keep it in peak shape all year long.
How to Do It:
- Option 1: Run the mower until the tank is empty, ensuring no fuel remains.
- Option 2: Add a fuel stabilizer to the tank if fuel remains, following the product’s instructions. Run the mower briefly to circulate the stabilizer.

3. Change the Oil
Why It’s Important:
Changing your mower’s oil before winter isn’t just a maintenance step—it’s a key factor in keeping your machine running like new. Fresh oil provides a protective barrier for the engine’s moving parts, helping to prevent wear and damage over the winter months. Meanwhile, old oil can break down, becoming contaminated with dirt and debris that can harm engine components during storage. By taking a few minutes to change the oil now, you’ll set your mower up for a quick, smooth start in the spring and avoid potential costly repairs down the line.
How to Do It:
- Drain the old oil while the mower is slightly warm (but not hot).
- Refill with the appropriate grade of oil recommended by the manufacturer.
- Dispose of old oil properly at a recycling center.

4. Replace or Clean the Air Filter
Why It’s Important:
A clean air filter is like a breath of fresh air for your lawn mower’s engine! When the filter is clear and unobstructed, your mower’s engine can operate at peak efficiency, delivering the power and performance you need to tackle even the toughest grass. On the other hand, a clogged filter stifles the engine, causing it to struggle, consume more fuel, and even wear down faster over time. By taking a few moments to clean or replace the air filter before winter storage, you’re giving your mower a head start on the spring season. A clean filter keeps the engine well-ventilated, ensures smooth performance, and saves you the hassle of unexpected repairs down the line. Ready to give your mower that extra boost? Dive in and discover just how easy it is to keep it running like new!
How to Do It:
- Remove the filter and inspect it for dirt and wear.
- For foam filters, wash with soap and water, then dry.
- For paper filters, replace if dirty or worn.
5. Disconnect and Remove the Battery (for Battery-Powered Mowers)
Why It’s Important:
Sharp blades are one of the unsung heroes of lawn care, and giving them attention before winter can make a huge difference for your lawn. A clean, precise cut isn’t just about aesthetics; it’s key to keeping your grass healthy. When blades are sharp, they slice through each blade of grass cleanly, rather than tearing it. This reduces stress on the grass, helping it recover quickly and resist diseases that can thrive on ragged edges. Inspecting and sharpening your mower blades now also means you’ll be ready for the first cut of spring, avoiding those last-minute maintenance delays just as the growing season begins. With sharp, ready-to-go blades, you’ll kick off the season with a healthier lawn and get the jumpstart on keeping it lush and green.
How to Do It:
- Disconnect the battery following the manufacturer’s instructions.
- Store it in a cool, dry place away from direct sunlight.
- For lead-acid batteries, occasionally check the charge level and recharge as necessary.
6. Sharpen and Inspect the Blades
Why It’s Important:

With sharp, ready-to-go blades, you’ll kick off the season with a healthier lawn and get the jumpstart on keeping it lush and green.
How to Do It:
- Remove the blades and use a file or grinder to sharpen them.
- Check for any cracks, bends, or significant wear.
- If blades are damaged, replace them to start spring with fresh, sharp blades.
7. Store in a Cool, Dry Place
Why It’s Important:
Storing your mower in a protected area is one of the most crucial steps to ensure it remains in peak condition throughout the off-season. When exposed to the elements, especially moisture from rain or snow, your mower can quickly fall victim to rust and corrosion. This not only affects the exterior of the machine but can also damage the internal components, leading to costly repairs come springtime. By storing your mower in a dry, sheltered location, such as a garage or shed, you protect it from these damaging elements. A secure storage space also shields your mower from temperature fluctuations that could affect sensitive parts like the battery or engine. In fact, a little extra care in choosing the right storage spot can go a long way in extending the life of your lawn mower and ensuring it’s ready for action when the grass starts growing again. Don’t forget to cover your mower with a waterproof tarp or mower cover for that added layer of protection. This simple step keeps dust, dirt, and moisture at bay, ensuring your mower is always ready to hit the ground running come spring!
How to Do It:
- Cover the mower to protect it from dust and moisture.
- Store it in a garage, shed, or other dry, sheltered place.

Frequently Asked Questions
Can I skip changing the oil if I didn’t use the mower often this year?
Even if you’ve used the mower sparingly, changing the oil before winter is still recommended to prevent contaminants from damaging the engine during storage.
What should I do if I don’t have a dry place to store my mower?
If you don’t have indoor storage, consider using a durable waterproof cover to shield the mower from the elements.
Is it okay to leave fuel in the tank without a stabilizer?
It’s best to add a stabilizer or drain the tank completely. Fuel left untreated can cause engine problems due to buildup and clogging over time.
