How to Winterize Your Lawn Mower
As the crisp fall air settles in and the leaves start to change color, many Virginia homeowners begin to think about preparing their outdoor equipment for the winter months. One of the most important pieces of equipment to properly maintain and store is your lawn mower. Storing it correctly can extend its lifespan and ensure it's ready to go when the warmer months return. In this guide, we’ll walk you through everything you need to know about winterizing and storing your lawn mower in Virginia, from the right time to stop mowing to maintenance tips that will protect your investment.
When to Start Winterizing Your Lawn Mower in Virginia
In Virginia, the best time to start winterizing your lawn mower is typically in late fall, between mid-November and early December. This is when the temperatures begin to dip consistently below 50°F, and the mowing season is coming to an end. Keep an eye on the weather—if the first frost is near, it's time to prepare your mower.
Starting the winterization process before the colder weather fully sets in ensures your mower is ready for storage and helps prevent damage from freezing temperatures and moisture. Be sure to complete the winterization before any snow or freezing rain arrives, as these conditions can complicate the process.
Safety First: Preparing for Winterizing Your Lawn Mower
Before diving into the winterizing process, it's essential to prioritize safety. Follow these basic safety tips to ensure you work efficiently and safely:
- Turn Off the Mower: Always ensure the mower is powered off, with the ignition switch in the "off" position, and the engine has cooled down completely before starting any maintenance.
- Disconnect the Spark Plug: To avoid accidental starting, disconnect the spark plug wire before performing any work on the mower. This adds an extra layer of safety while you're handling sharp tools or cleaning the engine.
- Remove the Battery (If Applicable): If your mower is electric or has a battery, remove it. Store the battery in a cool, dry location to avoid the battery draining or freezing over the winter months, and consider charging it periodically to maintain its life.
- Work in a Well-Lit, Ventilated Area: Make sure you’re working in a well-lit and open space, such as a garage or shed, where you can easily see what you're doing and avoid any tripping hazards. A clutter-free workspace will help you stay organized.
- Use Proper Tools and Wear Safety Gear: Use the appropriate tools for the job and consider wearing gloves and safety goggles, especially when cleaning the blades or handling the engine components.
Taking these precautions will ensure a safe and smooth winterizing process for both you and your mower.
1. Clean Your Mower Thoroughly
Start your lawn mower winterization by giving it a good cleaning. This step will help prevent the buildup of grass clippings, dirt, and debris, which can cause rust and damage over time.
- Remove the Grass Clippings: After mowing your last lawn of the season, use a stiff brush, putty knife, or scraper to remove any grass clippings, dirt, and debris from the mower deck, blades, and wheels.
- Wash the Deck: If possible, use a wet rag to wash down the underside of the mower deck to remove dirt and grass. Be sure to dry it thoroughly afterward to prevent rusting. Avoid using a hose, as excess water can cause rusting or damage to internal parts.
- Clean the Blades: Wear gloves and check the blades for any clumps of grass or dirt. Clean them with a rag or brush. Regularly cleaning the blades helps maintain their sharpness and prevents the accumulation of harmful debris.
2. Drain the Gas Tank
Gasoline can go stale over the winter, breaking down and gumming up the carburetor, which will cause issues when starting your mower in the spring. To avoid any fuel-related problems, drain the gas tank completely.
- Drain the Tank: Start the mower and let it run until the tank is empty. Be sure to dispose of the gas properly, following local regulations. Always handle gasoline carefully to avoid spills and accidents.
- Use Fuel Stabilizer: If you don’t want to go through the trouble of draining it, you can use a fuel stabilizer instead. Simply add the stabilizer to the gas tank, then run the engine for a few minutes to ensure the stabilizer is mixed throughout the fuel system. This helps prevent the fuel from breaking down and clogging the carburetor.
3. Change the Oil
Old oil can become thick and ineffective, which is why it’s important to change your mower's oil before storing it for the winter. Fresh oil helps protect the engine during long periods of inactivity.
- Check Your Owner's Manual: Follow the manufacturer’s instructions for oil changes, including the recommended oil type. Different mower models may require different types of oil for optimal performance.
- Replace the Oil: Drain the oil and replace it with fresh oil to keep the engine in good shape. Dirty oil can break down and cause engine problems if left over the winter months.
- Dispose of Old Oil: Make sure to properly dispose of the used oil by taking it to a recycling center or an auto parts store that accepts used oil.
Never dispose of old oil down the drain or in regular trash!
4. Replace the Air Filter
A clogged or dirty air filter can reduce your mower’s performance and efficiency. Before storing your mower, check the air filter and replace it if it’s dirty or damaged.
- Clean the Filter: If the air filter is reusable, clean it with compressed air or wash it according to the manufacturer’s instructions. A clean filter ensures proper airflow and engine efficiency.
- Replace the Filter: If it’s too worn, replace it with a new one. A new filter can make a noticeable difference in engine performance, especially when the mower is restarted in the spring.
5. Sharpen or Replace the Blades
Blades can dull after a season of mowing, which may not only make your mower work harder but can also tear the grass instead of cutting it cleanly. Clean, sharp blades are essential for a healthy lawn, so now is a great time to sharpen the blades or replace them if they’re too damaged.
- Sharpen the Blades: Remove the blade(s) carefully and use a sharpening tool or file to smooth out the edges. Sharpening blades can restore cutting efficiency, ensuring your mower runs at peak performance.
- Check for Damage: If the blades are bent or severely worn, it may be time to replace them. Dull or damaged blades can cause uneven cuts and strain the mower's engine.
6. Check the Spark Plug
A worn spark plug can lead to starting problems in the spring. Inspect the spark plug and clean it if necessary. If the spark plug is damaged or heavily worn, it’s a good idea to replace it.
- Inspect and Clean: If the spark plug appears dirty, use a wire brush to clean it. Cleaning the spark plug removes buildup that may hinder engine function.
- Replace if Needed: If cleaning doesn’t improve performance, replace the spark plug with a new one that meets the manufacturer’s specifications. A fresh spark plug ensures easier starting and more reliable engine performance.
7. Lubricate Moving Parts and Blades
Proper lubrication is essential to keep your mower running smoothly and to prevent rust and wear on moving parts. Before storing your mower for the winter, take the time to grease the key components and lubricate the blades.
- Lubricate the Blades: Apply a light coat of oil or a specialized lubricant to the underside of the mower deck and the blades. This helps prevent rust and ensures the blades stay sharp and free from debris buildup. Be sure to wipe off any excess lubricant to avoid attracting dirt and grass during future use.
- Grease Moving Parts: Many mowers have moving parts like wheels, pulleys, and linkage that can wear out without proper lubrication. Use a grease gun to apply lubricant to the mower's grease fittings, if applicable, or use a spray lubricant on pivot points and cables. This will help keep these components working smoothly and reduce friction, which can cause wear and tear over time.
Taking these extra steps to lubricate your mower ensures that all moving parts stay in top condition during the winter months, making it easier to get your mower running efficiently when spring comes around.
8. Store Your Mower Properly
Now that your mower is clean, fueled, and maintained, it’s time to store it for the winter. Choosing the right spot to store your lawn mower is key to ensuring its longevity. Ideally, you want to store it in a dry, cool location like a shed, garage, or basement. Here are a few tips for storage:
- Avoid Storing Outdoors: t’s essential to keep your mower out of the elements. Prolonged exposure to rain, snow, or humidity can cause rust, corrosion, and damage to the engine. A covered or enclosed space will provide better protection from the weather.
- Elevate the Mower: If possible, raise the mower slightly off the ground by using a storage rack or a pallet. This helps prevent moisture from seeping into the mower and keeps it off potentially damp floors, preventing rust.
- Cover the Mower: If you have to store it in an unheated shed or garage, consider covering the mower with a tarp or protective cover to shield it from dust and debris. A proper cover can also prevent moisture buildup and rust formation during the winter.
If your mower is exposed to humid conditions, consider investing in a rust prevention spray for the deck and blades.
9. Check Tires
Check the mower’s tires for any damage or deflation. Over the winter, tire pressure can drop, causing flat spots or damage. If needed, inflate the tires or replace them.
- Inflate the Tires: Ensure the tires are properly inflated to the manufacturer's specifications. This will help keep the tires in good shape and prevent damage.
- Replace if Necessary: If any tires are cracked or worn, replace them before spring mowing. Damaged tires can affect mower performance and stability when in use.
