How To Drain Gas From Riding Mower? Clearly Explained!

Empty the gas tank Unused gas left in a mower over the winter can get stale, gumming up the carburetor and inviting rust. First, add fuel stabilizer to the tank, then run the mower to distribute it through the system. After turning the mower off, suck excess gas into a gas can. Fill the can with gas and fill it with water.

The can should be about the size of a soda can, with a hole in the bottom for the hose to go through. If you don’t have a hose, you can make one by cutting a piece of PVC pipe about 1/2-inch in diameter and fitting it into the hole.

You can also use a garden hose if you have one, but it won’t be as strong as the PVC, so you’ll need to make sure it’s long enough to reach all the way down the length of the fuel tank. Make sure the water is at a temperature of at least 70 degrees F. When you’re ready to fill up, turn on the motor and let it run for a minute or two.

Then turn it off, and wait a few minutes before filling up again.

Do you need to drain gas from lawn mower?

Draining fuel allows oxygen to enter the lawn mower’s carburetor. It is not possible to get every last drop of gasoline out. When oxygen attacks the small fuel droplets left behind, it causes gum-like deposits to form on the surface of the fuel. These deposits are called “gumballs.” Gumball deposits can be removed by soaking the gumballs in a solution of hydrogen peroxide (H2O2) and water for a few minutes.

The solution can then be rinsed off with water. If you don’t have access to a hose, you can also use a garden hose to rinse the gummy deposits off. You may need to use more water than you think you’ll need, but it’s worth it to remove the deposits.
