How to Drain Gas From Husqvarna Riding Lawn Mower

It seems common sense to drain gas from the lawnmower, but it isn’t changing the gas in your lawnmower for some reason. It might seem obvious that you should constantly drain and replace the gas after every use. Still, many people neglect this simple procedure because they think they’re doing their yard a favor by using as little gas as possible.

Most people don’t realize that not changing out the old gas with fresh fuel can cause serious problems, including making your engine run poorly or even breaking down completely. However, changing the gas on your Husqvarna riding lawnmower is reasonably easy.

To do so, you’ll need to start by removing the cap of the tank and then using a hose or siphon pump to suck up all of its contents. If you’re not confident, read this blog post on how to drain gas from a Husqvarna riding lawn mower so that the process may become easier for you.

How to Drain Gas From Husqvarna Riding Lawn Mower

8 Reasons Why you Should Drain Gas from Husqvarna Riding Lawn Mower:

We discussed some reasons before knowing how to drain gas from the Husqvarna riding lawn mower. So that you know the importance of this procedure.

1. Fresh gas causes gum deposits to form on the inside of your engine, which eventually causes fuel lines and carburetor jets to get clogged up.

2. As time passes, dirt, debris, and lead particles can build up in your fuel tank and mix with your gas. This mixture can reduce the octane rating of your gasoline, meaning your engine may not run as well.

3. Old gas loses its ability to lubricate moving engine parts, turning your lawnmower into an expensive paperweight in no time flat.

4. Oxygen in the air causes old gas to form sludge in the bottom of gas storage tanks. Sludged-up fuel lines cause buildup, which gets mixed into the fuel supply, causing major engine problems down the road.

5. Modern gas stabilizers prevent old gas from going bad by keeping the fuel fresh during long-term storage. 

6. Gas can vaporize and escape through small holes in your lawnmower’s tank over time, meaning that you may be pumping gas that no longer contains enough octane to run your engine.

7. Carbon can build up in the combustion chamber of your lawnmower’s engine, causing severe damage over time.

8. Dirt and debris enter fuel tanks through tiny holes meant for vapor control during storage periods. This contamination can cause sudden breakdowns on the side of the road when you’re in a hurry.

Directions: How to Drain Gas From Husqvarna Riding Lawn Mower

Here we will discuss how to drain gas from a Husqvarna riding lawn mower. Follow these steps so you have a clear idea and can apply it to your problems.

Step 1: Remove the Gas Cap. 

The first step in emptying the gas tank on a Husqvarna riding lawn mower is to remove the gas cap and set it aside in a safe place where you won’t lose it. This will allow air to enter the tank so all the gasoline can be siphoned out.

Step 2: Check for Any Dirt and Debris:

Check for Any Dirt and Debris

Check the gas cap inside to ensure there is no dirt or debris on it. Although this seems simple enough, many people often skip this step and later find themselves having to clean fuel residue off of their mower engine because they didn’t inspect the cap before setting it aside.

Step 3: Check for Residue Around the Gas Tank:

After double-checking the gas cap for dirt and debris, look around the gas tank’s opening. If there is any residue on it or around it, make sure to get rid of it before draining the tank. This means that if there was leftover gasoline in there from last season and you didn’t clean it up, now would be the time to do so before moving on.

Step 4: Position the Lawnmower Over an Open Container

Position your mower over a large container or sink by lining it up with the gas cap hole. Use blocks or bricks to support the frame of your machine if you are working on a hillside since you don’t want this heavy piece of equipment to tip forward onto you.

Step 5: Attach a Hose or Siphon Pump to a Gas Tank

Attach your hose or siphon pump to the gas cap opening on your mower. If you are using a siphon pump, it will have two tubes—one for air to enter and one for gasoline to leave with a handle attached to the middle of them. Depending on how bad the gas you are trying to empty into the container below, you may have to start this process by sucking in some air first.

To do so, place the open end of the siphon hose into the gas tank opening and suck on it until you get a little bit of gasoline moving through. Then, place your free hand over the other end of the hose or use another section of the hose clipped to the other end so that gasoline won’t drain back into the tank and you don’t want gas in your lungs.

Step 6: Begin Draining Gasoline

Once you start draining, make sure to check the fuel level in the container every few minutes to catch all of the gasoline. When you are satisfied with how much gasoline you have collected, you can either put the cap back on your gas tank or just let it sit for a while until no more gasoline comes out.

Step 7: Remove the Gas Tank From Your Mower

Once you’ve emptied all of the gas from your mower, you’ll want to remove the tank entirely. It is usually very easy to unscrew with a wrench or socket wrench, then carry it over to its designated storage area until next season.

Step 8: Clean Up and Put Everything Back

Once you are sure that all of the gasoline has left your mower’s fuel tank, make sure to clean up any remaining fuel or residue from around the gas cap hole. Put everything back together, and you’re all done!

Tips to Maintain Your Lawn Mower Gas Tank:

1. Drain and replace gas and oil at the end of each mowing season. If you live in a cold-weather climate, run the engine for about five minutes after the final cut to empty out all residual fuel from your lawnmower.

2. Keep your lawn mower’s air filter clean (replace if necessary). As much as half of your engine’s fuel is turned into unburned hydrocarbons through normal air-fuel combustion. A clean air filter lowers unburned hydrocarbon emissions, which means better performance for your lawnmower and cleaner air.

3. Change or clean your mower’s spark plug at the beginning of each mowing season to ensure reliable performance.

4. Your mower’s tires should be inflated to the proper pressure indicated on your engine’s sticker (usually found near the spark plug). Under-inflated tires make it harder for your machine to turn over.

5. Keep your lawn mower’s underside clean. Dirt or mud buildup can cause fuel, air induction, or combustion chamber problems.

6. Maintain proper oil levels in your lawnmower. If the oil level is too high, it can cause dirt to collect on the piston and damage internal components. On the other hand, too low of a fuel level may cause problems with compression and reduce engine power.

Precautions and Safety Measures:

Ensure you’re wearing gloves before attempting any of the procedures listed below.

1. Ensure your lawnmower engine and the gas tank are excellent. Otherwise, burns could occur.

2. Be mindful of fuel spillage when handling or performing tasks involving gasoline or other combustible fluids.

3. Take great care to avoid contaminating the gas or fumes with oil, water, or solvents.

4. If you choose to use a hose or siphon pump, remember that only the clear hose should be used.

5. Be careful not to damage any components when draining gas from your Husqvarna riding lawnmower.

How to Locate the Gas Tank on a Husqvarna Riding Lawn Mower?

Before draining gas on your riding lawn mower, it’s essential to know where its gas tank is located. Check for a fuel gauge on your handlebar to find the gas tank. In front of this is a metal knob that will release the tank cover.

How to Locate the Gas Tank

If there is no fuel gauge, the gas tank will be located on the right side of the lawnmower. The gas cap is located on the front left side of the motor, just underneath where you attach your clutch control. To remove the gas cap, twist it counterclockwise with your hand until it comes off.


In conclusion, changing the gas in your lawn mower is a good idea. This will help avoid any sediment buildup and ensure that you use fresh fuel for this important task. You can use either a siphon pump or hose to drain all the gas from your Husqvarna riding lawnmower.

Once you have drained out all of its contents, make sure to replace the cap before filling up with new gasoline again! After going over these steps on how to drain gas from Husqvarna riding lawn mower, we hope that our article has been helpful!
