Step-by-Step Winterization Process
Now, let’s dive into the detailed steps of winterizing your lawn mower. Follow these instructions carefully to ensure your mower is well-protected for the winter.
Stabilizing or Draining the Fuel
The first crucial step is to deal with the fuel in the tank. Gasoline can degrade over time, forming gum and varnish deposits that can clog the carburetor and fuel lines.
You have two options: add fuel stabilizer to the existing fuel or drain the fuel completely.
To use fuel stabilizer, add the recommended amount (as per the product instructions) to the fuel tank. Then, run the engine for a few minutes to allow the stabilized fuel to circulate through the fuel system. This will protect the fuel system from corrosion and prevent the formation of gum and varnish.
If you prefer to drain the fuel, disconnect the fuel line from the carburetor and drain the fuel into a suitable container. Be sure to do this in a well-ventilated area away from any sources of ignition. Once the tank is empty, start the engine and let it run until it stalls to ensure the fuel lines and carburetor are also empty.
Changing the Oil
Next, it’s time to change the engine oil. Old oil contains contaminants that can corrode engine parts over the winter.
Start by warming up the engine slightly, as warm oil flows more easily. Then, locate the oil drain plug (refer to your owner’s manual if needed) and place a drain pan underneath. Remove the drain plug and allow the old oil to drain completely.
Once the oil has drained, replace the drain plug and tighten it securely. Then, remove the oil filter (if your mower has one) and replace it with a new one. Finally, refill the engine with the correct type and amount of oil, as specified in your owner’s manual. Check the oil level with the dipstick to ensure it’s within the recommended range.
Replacing the Spark Plug
The spark plug is a vital component of the engine’s ignition system. Replacing it before winter storage can prevent starting problems in the spring.
Use a spark plug wrench to remove the old spark plug. Inspect the spark plug for any signs of wear or damage, such as cracked porcelain or excessive carbon buildup. If the spark plug looks good, you can clean it with a wire brush and reuse it. However, it’s generally recommended to replace the spark plug every year for optimal performance.
Install the new spark plug and tighten it securely. Be careful not to overtighten it, as this can damage the threads in the cylinder head.
Cleaning the Mower Deck and Undercarriage
A clean mower deck and undercarriage are essential for preventing rust and corrosion. Grass clippings and debris can trap moisture against the metal, leading to damage over the winter.
Use a scraper or putty knife to remove any accumulated grass clippings from the underside of the deck. Then, use a wire brush to scrub away any stubborn dirt or rust.
You can also use a garden hose to wash down the mower deck, but be sure to avoid getting water into the engine or electrical components. Allow the mower to dry completely before storing it.
Cleaning the Air Filter
The air filter prevents dirt and debris from entering the engine. A dirty air filter can restrict airflow and reduce engine performance.
Remove the air filter cover and take out the air filter. Inspect the air filter for dirt and damage. If it’s a paper filter, you can try tapping it gently to remove loose dirt. However, if it’s heavily soiled or damaged, it’s best to replace it with a new one.
If it’s a foam filter, you can wash it with warm, soapy water. Rinse it thoroughly and allow it to dry completely before reinstalling it.
Lubricating Moving Parts
Lubricating moving parts will help prevent rust and corrosion and ensure smooth operation in the spring.
Use a multi-purpose lubricant to lubricate all moving parts, such as the wheels, axles, and control cables. Pay special attention to any areas that are prone to rust or corrosion.
This will help keep these parts moving freely and prevent them from seizing up over the winter.
Battery Care
If your lawn mower has a battery, it’s important to take steps to protect it during the winter. Cold temperatures can drain the battery and reduce its lifespan.
Remove the battery from the mower and clean the terminals with a wire brush. Store the battery in a cool, dry place, such as a garage or basement.
You can also use a battery maintainer to keep the battery charged during the winter. A battery maintainer will automatically charge the battery when needed, preventing it from losing its charge.
Storing Your Lawn Mower
Finally, it’s time to store your lawn mower for the winter. Choose a dry, sheltered location, such as a garage or shed.
Cover the lawn mower with a tarp or blanket to protect it from dust and moisture. This will help keep it clean and prevent rust.
Avoid storing the lawn mower in a damp or humid location, as this can promote rust and corrosion.
Specific Considerations for Different Types of Mowers
The winterization process may vary slightly depending on the type of lawn mower you have. Here are some specific considerations for different types of mowers.
Gasoline-Powered Mowers
For gasoline-powered mowers, it’s especially important to stabilize or drain the fuel to prevent carburetor problems. Also, be sure to change the oil and replace the spark plug.
Electric Mowers
For electric mowers, battery care is particularly important. Remove the battery and store it in a cool, dry place. You can also use a battery maintainer to keep the battery charged during the winter.
Riding Mowers
Riding mowers have more complex systems than walk-behind mowers. In addition to the steps outlined above, you may also need to lubricate the steering linkage, check the tire pressure, and inspect the belts and hoses.
