How to drain gas from riding lawn mower?

The basic query is, why do we have to do that? What is the reason that we should know how to drain gas from riding lawn mower? 

When your fuel starts to rest in the base of your fuel tank, it starts to deposit residuals of ethanol to the bottom. This can lead to the fuel of lower quality for the combustion of your engine, and your mower will start to go rougher and makes it harder to start because of liquid fuel clotting.

In the winter season, draining off your fuel after every drive is healthy for your riding lawn mower’s engine health. 

By keeping it in practice will let you know how important it is for you. It can also tell you how it will be far off from the poor performance in the upcoming spring.

Now coming up to the next part, in order to be able to do that at your place because it will not be convenient for you to take it every time for service. 

Some simple steps 

There are some of the basic and easy steps that you can perform yourself to drain your fuel gas. The following process contains all the necessary steps:

First of all, your riding lawn mower needs to be in a stationary state on some flat surface where the fuel can settle evenly.

Take some bottles or even jugs with the caps open next to your lawnmower so that you start filling them up without wasting.

Get some funnel or pipe of brass metal and clear it up of any gas.

Now is the time to take off the fuel tank cap. Start rotating it anti-clockwise to open it.

As soon as you are done with moving it, insert that funnel in the tank, and the other end should be getting inside the jug or your air-tight regular bottle. If you do not see the bottle filling up, try to shake the bottle and move the funnel in and out to start the process of siphoning. After a little while, you will see the gas moving inside your bottle from your tank.

Be aware of how much your bottle is filled. When you see the three-fourth of it is filled up, take out the funnel so that the remaining volume will be covered up with the gas in the funnel.

Continue doing that process until you see that no more gas is coming out through the funnel.

The remaining gas should go out. Lose the crank of your mower and let it all out until your lawnmower becomes idle and free from all gasoline.

Cover up the bottles with caps or some lid to avoid spillage. It is even better and safer to use duct tape on them.

Now it requires some rinsing. Take more than half of the bucket of water, depending on the tank’s size, and fill it up again with water with the help of your siphon. Put the siphon then to dry out before using it anywhere else.

Now instead of taking the whole mower, take that taken out gasoline to some recycling center as you cannot keep them anywhere, stopping it from making pollution.

After draining out the gas, fill up the tank with new fuel every time. This process will take a little of your efforts, but the results will be guaranteed. The life of your riding lawn mower will tend to elongate. Doing it in the fall season is a must because your gasoline may start to freeze. If not, then it will settle down in the bottom, and you should be taking good care of your mower, so don’t let that happen.
