The smell of freshly cut grass and the satisfying whir of a lawn mower – these are the sounds and scents of a well-maintained lawn. But what happens when your lawn mower sits idle for a while, and the fuel inside starts to go bad? That’s where the need to drain your gas tank comes in. This article will guide you through the process of draining a lawn mower gas tank, ensuring your lawn mower stays in top shape for years to come. We’ll cover everything from safety precautions to the most effective draining techniques, and address common questions that might arise along the way. So, let’s dive in!
Why Drain Your Lawn Mower Gas Tank?
Draining your lawn mower gas tank is a crucial maintenance task that will help prolong the life of your mower. Here’s why:
- Fuel Stability: Gasoline breaks down over time, especially when exposed to air and heat. This can lead to gum and varnish deposits in the fuel system, clogging your carburetor and affecting performance.
- Engine Problems: Old, stale fuel can create ignition issues, making your lawn mower difficult to start or causing it to sputter and stall.
- Storage: If you’re storing your lawn mower for an extended period, draining the gas tank will prevent fuel from deteriorating and potentially damaging the engine.
Safety First: Essential Precautions Before You Begin
Before tackling any maintenance task on your lawn mower, safety should be your top priority. Here’s what you need to do:
- Disconnect the Spark Plug: This step is essential to prevent accidental ignition while you’re working on the fuel system.
- Wear Protective Gear: Always wear safety goggles to protect your eyes from splashes and gloves to protect your hands.
- Work in a Well-Ventilated Area: Gasoline fumes are flammable and toxic, so make sure you’re working in an open space with plenty of fresh air.
Step-by-Step Guide to Draining Your Lawn Mower Gas Tank
Now that you’re prepared, let’s proceed with draining the gas tank:
1. Locate the Fuel Tank Drain Valve:
Most lawn mowers are equipped with a drain valve located at the bottom of the gas tank. This valve is typically a small, threaded plug or a lever that you can turn to open the drain.
2. Prepare a Container:
Find a suitable container, such as a clean metal can or a plastic jar, to collect the drained fuel. Make sure the container is large enough to hold all the gasoline in the tank.
3. Open the Fuel Tank Drain Valve:
Turn the drain valve counterclockwise to open it. If it’s a lever, simply move it to the open position. The gasoline will start to flow out of the tank.
4. Catch the Fuel:
Place the container underneath the drain valve to catch the gasoline as it flows out.
5. Empty the Tank:
Allow the fuel to drain completely. You may need to tilt or shake the mower slightly to help the fuel flow out.
6. Close the Drain Valve:
Once the gas tank is empty, carefully close the drain valve by turning it clockwise or moving the lever back to the closed position.
7. Dispose of the Fuel Properly:
Gasoline is a hazardous material and should be disposed of responsibly. Do not pour it down the drain or on the ground. Contact your local waste management facility for information on proper disposal options.
Additional Tips for Draining Your Lawn Mower Gas Tank
- Stabilize the Fuel: If you’re not going to drain the tank immediately, consider adding a fuel stabilizer to prevent the gasoline from deteriorating.
- Clean the Tank: After draining the fuel, it’s a good idea to clean the inside of the gas tank with a clean cloth or a gas tank cleaner.
- Inspect the Tank and Drain Valve: While you’re cleaning the tank, check for any cracks, leaks, or corrosion in the tank and the drain valve. If you find any damage, it’s best to replace the tank or valve.
What to Do with the Drained Fuel?
You have a few options for dealing with the drained fuel:
- Use it in a Small Engine: If the fuel is relatively fresh and you’re not worried about gum or varnish, you can use it in other small engines, such as a generator or a trimmer.
- Give it to a Friend: If you have a friend who uses small engines, they might be able to use the fuel.
- Properly Dispose: If you can’t use it, the safest option is to dispose of it properly. Contact your local waste management facility to find out how to do this.
Troubleshooting: Common Issues When Draining a Gas Tank
- The Drain Valve is Stuck: If the drain valve is stuck, you can try using a wrench to loosen it. If it’s still stuck, you may need to replace the valve.
- The Tank Won’t Drain Completely: Sometimes, the fuel tank may not drain completely. You can try tilting the mower or using a small suction device to remove any remaining fuel.
- Leaking Fuel: If you notice fuel leaking from the drain valve after you close it, it’s likely the valve is damaged and needs to be replaced.

FAQs
Why should I drain my lawn mower gas tank?
Draining your lawn mower gas tank is important for several reasons. Firstly, gasoline can degrade over time, losing its potency and becoming harder to ignite. This can lead to engine problems and difficulty starting the mower. Secondly, old gasoline can form varnish and gum deposits inside the fuel system, clogging fuel lines and carburetors. This can significantly affect engine performance and efficiency. Finally, draining the gas tank prevents potential fire hazards associated with storing gasoline for long periods.
How often should I drain my lawn mower gas tank?
It’s generally recommended to drain your lawn mower gas tank every 30 days or before storing it for an extended period. This ensures that the fuel remains fresh and prevents the formation of harmful deposits. However, if you use your mower frequently, you can drain the tank less often, but it’s still good practice to do so at least once a year. Remember, the more you use your mower, the less likely it is that fuel will degrade significantly.
What are the risks associated with draining a gas tank?
Draining a gas tank can be a relatively safe process, but there are some risks associated with it. Gasoline is flammable, so always work in a well-ventilated area, away from any open flames or heat sources. Additionally, gasoline fumes can be harmful, so it’s important to wear appropriate protective gear, such as gloves and eye protection. Finally, be cautious when handling the gas tank and its contents, as they can be slippery and cause spills or injuries.
What tools do I need to drain a lawn mower gas tank?
You’ll need a few basic tools to drain your lawn mower gas tank. A container or jar to collect the gasoline is essential. Make sure it’s large enough to hold the entire contents of the tank. You’ll also need a siphon pump or a turkey baster to transfer the gasoline from the tank to the container. If you’re using a siphon pump, ensure it’s long enough to reach the bottom of the tank. Lastly, a pair of gloves and eye protection will help protect you from spills and fumes.
What should I do with the drained gasoline?
Once you’ve drained the gasoline from your lawn mower tank, you need to dispose of it properly. You cannot simply pour it down the drain or into the trash. Instead, find a local gas station or auto parts store that accepts used gasoline for recycling or disposal. Alternatively, you can try contacting your local waste management facility to learn about their guidelines for disposing of used gasoline. Never leave a container of gasoline unattended, and always store it in a safe and well-ventilated location.
Can I use the drained gasoline again?
Technically, you can reuse the drained gasoline, but it’s not recommended. While the gasoline may still ignite, it’s likely to have lost some of its potency and may not burn as efficiently, leading to engine performance issues. It’s best to use fresh gasoline for your lawn mower to ensure optimal performance and prevent potential engine problems.
What should I do after draining the gas tank?
After you’ve drained the gas tank, it’s essential to clean the inside of the tank and the fuel line to remove any remaining fuel or debris. You can use a clean cloth or a small brush to clean the inside of the tank. For the fuel line, you can use a compressed air can to blow out any remaining particles. Once the tank and fuel line are clean, you can fill the tank with fresh gasoline and restart the mower. It’s also a good idea to change the air filter and spark plug as part of your regular maintenance routine.
