Step-by-Step Guide to Draining Your Lawn Mower Gas Tank
Now, let’s get into the specifics of draining your lawn mower gas tank:
Step 1: Locate the Fuel Tank Drain Valve
Most lawn mowers come equipped with a fuel tank drain valve, typically located at the bottom or side of the tank. It might be a small, lever-like valve or a screw-type valve. If your mower doesn’t have a drain valve, you’ll need to use a siphon to remove the fuel (more on that later).
Step 2: Securely Position the Container
Place your clean, empty container directly beneath the fuel tank drain valve. Ensure the container is positioned securely and won’t tip over during the draining process.
Step 3: Open the Drain Valve
Carefully open the fuel tank drain valve, allowing the gasoline to flow into the container. It’s essential to do this slowly and steadily to prevent spills and ensure all the fuel is collected.
Step 4: Monitor the Flow and Close the Valve
Watch the fuel drain into the container. Once the flow stops, close the drain valve tightly. If the fuel doesn’t drain completely, you might need to shake or tilt the mower gently to encourage the last bit of fuel to drain.
Step 5: Double-Check for Remaining Fuel
After closing the valve, examine the fuel tank to ensure no fuel remains. If there’s a small amount left, you can use a siphon to extract it.
Step 6: Clean Up and Dispose of Fuel Properly
Wipe up any spills or drips around the drain valve and the container. Dispose of the gasoline properly according to your local regulations. It’s generally advisable to take the fuel to a designated waste collection site or an automotive shop.
Step 7: Add Fresh Fuel (Optional)
Once the tank is drained and cleaned, you can add fresh fuel if you plan to use your mower shortly.
Alternative Methods: Siphoning Fuel
If your lawn mower doesn’t have a drain valve, you can use a siphon to remove the fuel. Here’s how:
What You’ll Need
- A siphon pump: These are available at most hardware stores and online retailers.
- A clean, empty container: Ensure the container is specifically designed for gasoline.
- A length of clear tubing: This will help you visualize the fuel flow.
Steps
- Fill the Tube: Place one end of the siphon tubing in the fuel tank and the other end in the container.
- Prime the Tube: Suck on the end of the tube to create a vacuum, which will draw fuel up into the tube. You can also use a siphon pump to prime the tubing.
- Start the Flow: Once the tube is primed, the fuel will start to flow from the tank into the container.
- Monitor the Flow: Keep an eye on the fuel flow and adjust the siphon as needed.
- Complete the Drain: Continue siphoning until all the fuel is removed from the tank.
Important Safety Considerations
- Always work in a well-ventilated area: Gasoline fumes are flammable and can be dangerous.
- Never smoke or use open flames near gasoline: Gasoline is highly flammable.
- Wear protective gear: Gloves and eye protection are essential to prevent contact with gasoline.
- Properly dispose of fuel: Never pour gasoline down the drain or into the soil. Contact your local waste management agency for proper disposal instructions.
Tips for Maintaining Your Lawn Mower Fuel System
Here are some additional tips to keep your lawn mower fuel system running smoothly:
- Use fresh fuel: Avoid using old or stale gasoline. Fuel should be replaced every 30 days for optimal performance.
- Store fuel properly: Store gasoline in a clean, sealed container in a cool, dry place.
- Add fuel stabilizer: Using a fuel stabilizer can help prevent fuel degradation during storage.
- Regularly clean the fuel system: Clean the fuel lines, carburetor, and fuel filter regularly to remove any debris or deposits.

Frequently Asked Questions
Why do I need to drain the gas tank of my lawnmower?
Draining the gas tank of your lawnmower is essential for a few reasons. Firstly, it helps prevent the fuel from going bad. Gasoline degrades over time, especially when exposed to air and sunlight. This can cause engine problems, making it harder to start and run smoothly. Secondly, draining the gas tank allows you to perform maintenance tasks like cleaning the carburetor or replacing fuel lines without the risk of fuel spills. Lastly, it ensures a safe storage environment for your lawnmower, preventing any potential fire hazards.
How often should I drain my lawnmower’s gas tank?
The frequency of draining your lawnmower’s gas tank depends on how often you use it. If you use it regularly, you can probably get away with draining the tank every few months. However, if you store your lawnmower for an extended period, it’s best to drain the tank before putting it away. A good rule of thumb is to drain the tank at least once a year, even if you use the mower frequently. This helps prevent fuel degradation and ensures your lawnmower is ready for the next season.
Can I use the drained gas in another lawnmower?
While you can technically use the drained gas in another lawnmower, it’s not recommended. Gasoline starts to degrade as soon as it’s exposed to air.
