Draining gas from your lawn mower is an essential maintenance task for winterizing your mower or performing repairs.

This article provides step-by-step instructions for two methods of removing the gas from a lawn mower: one with a siphon and one without a siphon.

Follow the appropriate method based on the tools you have available.

How To Empty Gas From a Lawn Mower

Method 1: Draining with a Siphon

  1. Gather necessary materials: Before starting, gather a siphon pump, tubing, and a jerry can.
  2. Insert the tubing: Insert one end of the tubing into the gas tank of your lawn mower.
  3. Create suction: Use a siphon pump to create suction by following the manufacturer’s instructions.
  4. Start the flow: Once suction is created, the gas will start flowing through the tubing.
  5. Direct the gas: Direct the other end of the tubing into the jerry can to collect the drained gas.
  6. Monitor the process: Keep an eye on the flow of gas and ensure it is draining properly.
  7. Complete the process: Allow all the gas to drain into the jerry can before disconnecting the tubing.

Note: Follow safety precautions when working with gasoline and ensure proper ventilation.

Method 2: Draining without a Siphon

  1. Gather necessary materials: Prepare a gas can and a funnel for this method.
  2. Open the gas cap: Begin by opening the gas cap on your lawn mower.
  3. Position the funnel: Place the funnel securely in the gas can.
  4. Lift and tilt: Carefully lift and tilt the mower downward towards the gas can, ensuring it is stable and supported.
  5. Drain the gas: Slowly pour the gas from the mower into the funnel, allowing it to flow into the gas can.
  6. Exercise caution: Be cautious while draining the gas to avoid spills or accidents.
  7. Complete the process: Continue draining until all the gas is transferred from the mower to the gas can.

Note: Take appropriate safety measures and perform this task in a well-ventilated area.

Additional Tips and Considerations

  1. Safety precautions: When working with gasoline, always wear protective gloves and eyewear. Avoid smoking or open flames in the vicinity.
  2. Proper disposal: Dispose of drained gas in accordance with local regulations. Contact your local waste management facility for guidance.
  3. Ventilation: Work in a well-ventilated area, preferably outdoors, to prevent the accumulation of potentially harmful fumes.
  4. Cleaning the fuel system: After draining the gas, consider cleaning the gas tank and fuel system to remove any residue or buildup.

By following these methods and tips, you can safely and effectively drain gas from your lawn mower, ensuring its optimal performance.
