What You'll Learn

Prepare the mower and gather tools
To prepare your Craftsman riding mower for fuel tank draining, park it on a level surface and turn off the engine. This ensures that the oil drains completely and prevents any accidental spillage. It is important to let the engine cool down before you begin, as a hot engine can cause burns. Next, disconnect the negative battery cable to prevent any sparks, and remove the spark plug wire to prevent the engine from accidentally starting while you work. If your mower has an oil filter, you will need an oil filter wrench to loosen and remove it. You will also need a wrench to remove the fuel line and a container to catch the drained fuel. It is important to dispose of the drained fuel properly. Other useful tools include shop towels or rags for cleaning up spills, safety glasses, and gloves to protect your eyes and hands. Before you begin, consult your owner's manual to locate the exact position of the oil drain plug and confirm the recommended oil type and quantity for your mower.

Disconnect the negative battery cable
Disconnecting the negative battery cable is an important step when draining the fuel tank of a Craftsman riding mower. This is because it prevents any sparks from occurring during the process, which could potentially cause an explosion.
To begin, locate the negative battery cable. It is usually black in colour and is often connected to the negative terminal of the battery, which is typically marked with a "-" symbol. Once located, proceed to carefully disconnect the cable. Make sure to use the appropriate tools, such as a wrench or pliers, to loosen any connections if necessary.
It is important to note that the battery is typically located near the engine or in a designated battery compartment. So, be sure to consult your Craftsman riding mower's user manual to identify the exact location of the battery and cable. Additionally, wear protective gear, such as safety goggles and gloves, to ensure your safety during the process.
After disconnecting the negative battery cable, set it aside in a safe place where it will not cause any accidental connections. Ensure that the cable is not damaged or frayed, as this could pose a safety hazard. Once the cable is safely disconnected and secured, you can proceed with the next steps of draining the fuel tank, such as removing the gas cap and draining the fuel into a suitable container.
By following these steps and taking the necessary precautions, you can effectively and safely disconnect the negative battery cable when draining the fuel tank of your Craftsman riding mower.

Remove the gas cap
To remove the gas cap from your Craftsman riding mower, start by parking the mower on a level surface and turning off the engine. This is important for safety reasons and to ensure that the oil drains completely.
Next, locate the gas cap on the fuel tank. The gas cap is usually on top of the fuel tank, and it can be removed by simply unscrewing it. Before removing the gas cap, place a container underneath the fuel tank to catch any fuel that may spill. Once you have located the gas cap, use a wrench or your hand to unscrew it in a counter-clockwise direction. If your gas cap is damaged or cracked, it may need to be replaced.
Set the gas cap aside in a safe place to avoid misplacing it or accidentally knocking it over. Now that the gas cap is removed, you can proceed with draining the fuel tank or performing any necessary maintenance or repairs on your Craftsman riding mower. Remember to dispose of the drained fuel properly and responsibly.

Drain the fuel
To drain the fuel tank on a Craftsman riding mower, first park the mower on a level surface and turn off the engine. It is important to disconnect the negative battery cable to prevent any sparks. Next, remove the gas cap and place a container under the fuel tank to collect the fuel.
Now, you need to locate the fuel line. This is usually a clear tube with fuel in it, found below the tank and before the carb. It will have a pinch-type collar on either end. Simply squeeze the tabs of the collar with a pair of pliers and pull the hose free. Allow the fuel to drain into the container.
Alternatively, use a wrench to loosen the fuel line at the tank and let the fuel drain into the container. Once the fuel has finished draining, be sure to dispose of it properly, then replace the fuel line and gas cap.
If you are removing the gas tank from the mower, you can drain the fuel into a fuel can. This can be done by opening the valve at the bottom of the tank or by sucking the gas out with a fuel pump.

Clean the tank
To clean the tank of your Craftsman riding mower, you will first need to remove it from the mower. It is important to follow the proper procedure to avoid damaging the mower or injuring yourself.

You can clean the tank with a simple solution of soap and water, or a mixture of water and vinegar. Fill the tank with your chosen cleaning solution and let it sit for a few hours.
After the solution has had time to work, rinse the tank thoroughly with warm water to remove any remaining soap, vinegar, or fuel residue. If your tank is made of plastic and has cracks or holes, you can try rinsing it out with warm soapy water to remove fumes, letting it dry, and then plastic welding the cracks or holes.
Once your tank is clean and dry, you can reinstall it in your Craftsman riding mower.
