The Importance of Proper Lawn Mower Storage
Investing time in preparing your lawn mower for storage offers significant benefits. First and foremost, it prevents fuel-related issues. Old fuel can degrade, leaving behind gummy deposits that clog the carburetor and fuel lines. This is a common cause of starting problems in the spring. Second, proper storage protects the mower from rust and corrosion. Moisture and temperature fluctuations can damage metal components, leading to costly repairs. Finally, taking the time to maintain your mower before storage extends its overall lifespan. A little preventative maintenance now can save you significant money and hassle in the long run.
Essential Preparation Steps: A Step-by-Step Guide
Before tucking your lawn mower away for the winter, follow these crucial steps to ensure it’s in tip-top shape when you need it again.
Cleaning Your Lawn Mower Thoroughly
The first step is to give your lawn mower a thorough cleaning. This removes accumulated grass clippings, dirt, and debris that can contribute to corrosion and attract pests.
Cleaning the Mower Deck
Disconnect the spark plug wire before starting any cleaning or maintenance. This prevents accidental starting. Turn the mower on its side (refer to your owner’s manual for the correct orientation to avoid oil leakage). Use a scraper or putty knife to remove caked-on grass clippings from the underside of the deck. A garden hose with a spray nozzle can be used to wash away remaining debris. Allow the deck to dry completely before proceeding. Consider using a wire brush to remove any rust spots.
Cleaning the Engine and Housing
Wipe down the engine and housing with a damp cloth to remove dirt and grime. Avoid spraying water directly onto the engine, as this can damage electrical components. Use a soft brush to remove debris from around the engine fins, which are crucial for cooling.
Fuel Management: Stabilizing or Draining
Fuel management is perhaps the most critical aspect of lawn mower storage. Gasoline can degrade over time, leading to starting problems and engine damage. You have two primary options: fuel stabilization or draining the fuel tank and carburetor.
Fuel Stabilization
Adding a fuel stabilizer to the gasoline in your tank is a simple and effective way to prevent fuel degradation. Follow the manufacturer’s instructions for the correct ratio of stabilizer to fuel. Run the engine for a few minutes after adding the stabilizer to ensure it circulates throughout the fuel system. This is a good option if you plan to use the remaining fuel next season.
Draining the Fuel System
Draining the fuel system completely eliminates the risk of fuel-related problems. First, siphon or drain the gasoline from the fuel tank into an approved container. Next, disconnect the fuel line from the carburetor and allow any remaining fuel to drain out. Finally, start the mower and let it run until it stalls. This ensures that any residual fuel in the carburetor is used up. Be sure to do this in a well-ventilated area.
Oil Change: Fresh Oil for Optimal Performance
Changing the oil before storing your lawn mower is highly recommended. Old oil contains contaminants that can corrode engine components over time.
Draining the Old Oil
Warm up the engine for a few minutes to make the oil flow more easily. Disconnect the spark plug wire for safety. Locate the oil drain plug (consult your owner’s manual). Place a drain pan under the drain plug and remove the plug to allow the old oil to drain completely.
Adding New Oil
Once the old oil has drained, replace the drain plug and tighten it securely. Consult your owner’s manual for the correct type and amount of oil to use. Pour the new oil into the engine through the oil fill port. Check the oil level with the dipstick to ensure it is at the proper level.
Spark Plug Maintenance
Inspect the spark plug for signs of wear or damage. A fouled or worn spark plug can cause starting problems.
Inspecting the Spark Plug
Remove the spark plug using a spark plug wrench. Inspect the electrode for carbon buildup, cracks, or other damage. If the spark plug is heavily fouled, it may need to be replaced.
Cleaning or Replacing the Spark Plug
If the spark plug is only slightly fouled, you can clean it with a wire brush. Re-gap the spark plug to the manufacturer’s specifications using a spark plug gapping tool. If the spark plug is damaged or heavily fouled, replace it with a new spark plug of the correct type.
Blade Sharpening: Ready for Next Season
Sharpening the mower blade before storage ensures that it will be ready for action next spring. A dull blade tears the grass, leading to a less healthy lawn.
Removing the Blade
Disconnect the spark plug wire for safety. Secure the blade with a block of wood to prevent it from turning. Use a wrench to loosen and remove the blade bolt.
Sharpening the Blade
Sharpen the blade using a metal file or a bench grinder. Maintain the original angle of the blade. Be careful not to overheat the blade, as this can weaken the metal.
Balancing the Blade
After sharpening the blade, balance it using a blade balancer. An unbalanced blade can cause excessive vibration and damage to the mower. If the blade is unbalanced, grind a small amount of metal from the heavier side until it is balanced.
Air Filter Inspection and Replacement
A clean air filter is essential for proper engine performance. A dirty air filter restricts airflow, leading to reduced power and increased fuel consumption.
Inspecting the Air Filter
Remove the air filter cover and inspect the air filter. If the air filter is dirty or damaged, it should be replaced.
Cleaning or Replacing the Air Filter
If the air filter is only slightly dirty, you can clean it by tapping it gently or using compressed air. If the air filter is heavily soiled or damaged, replace it with a new air filter of the correct type.
Choosing the Right Storage Location
The storage location is a critical factor in protecting your lawn mower from the elements. Choose a location that is dry, sheltered, and protected from extreme temperatures.
Ideal Storage Locations
A garage, shed, or covered carport are ideal storage locations. These locations provide protection from rain, snow, and sun. Avoid storing your lawn mower outdoors, as this can lead to rust, corrosion, and damage from the elements. If outdoor storage is unavoidable, cover the mower with a waterproof tarp.
Preparing the Storage Area
Clean the storage area thoroughly to remove any debris or pests. Place a sheet of cardboard or a plastic mat under the lawn mower to protect the floor from oil leaks.
Additional Tips for Optimal Storage
Here are some additional tips to help ensure your lawn mower is properly stored:
- Consult your owner’s manual: Your owner’s manual provides specific instructions for your model of lawn mower.
- Lubricate moving parts: Apply a light coat of oil or grease to moving parts, such as the wheels and cables, to prevent rust and corrosion.
- Cover the mower: Cover the mower with a tarp or lawn mower cover to protect it from dust and dirt.
