Is your Troy-Bilt lawn mower sitting idle for the season? Or perhaps you’re getting ready for a tune-up and need to remove the fuel? Draining the gas from your Troy-Bilt lawn mower is a crucial maintenance step that can prevent a host of problems, from stale fuel gumming up your carburetor to potential fire hazards.
Many homeowners hesitate to tackle this task, fearing it’s too complicated or messy. But the truth is, with the right knowledge and a few simple tools, you can efficiently and safely drain your mower’s fuel tank. This guide will walk you through the entire process, addressing common concerns and providing clear, actionable steps.
Why Drain the Gas From Your Troy-Bilt Lawn Mower?
Before we dive into the ‘how,’ let’s quickly touch on the ‘why.’ Draining your fuel tank is essential for several reasons:
- Seasonal Storage: If your mower will be unused for more than a month, draining the fuel prevents it from going stale. Old gasoline can degrade, leaving behind varnish and deposits that clog the carburetor and fuel system, making startup difficult next season.
- Carburetor Cleaning/Repair: Accessing and cleaning or repairing the carburetor often requires the fuel to be removed to prevent spills and further damage.
- Troubleshooting Fuel Issues: If your mower is experiencing fuel delivery problems, draining the tank allows for inspection and cleaning of the fuel system components.
- Disposal of Old Fuel: If you’ve accidentally put the wrong type of fuel in your mower, or if the fuel has been sitting for too long, draining it allows for proper disposal.
Understanding Your Troy-Bilt Mower’s Fuel System
Most Troy-Bilt lawn mowers, like many other brands, have a relatively straightforward fuel system. You’ll typically find:
- Fuel Tank: The reservoir for your gasoline.
- Fuel Line: A hose connecting the tank to the carburetor.
- Fuel Filter (optional but common): A small inline filter to catch debris before it reaches the carburetor.
- Carburetor: The component that mixes air and fuel before it enters the engine.
The method for draining the gas will depend on whether your mower has a dedicated drain plug on the fuel tank or carburetor, or if you’ll need to use an alternative method like siphoning. (See Also: Mastering Your Lawn: How to Cut Grass with a Riding Lawn…)
Methods for Draining Gas From Your Troy-Bilt Lawn Mower
There are a few primary ways to get the gas out of your Troy-Bilt mower. We’ll break down each method, starting with the easiest and most common.
Method 1: Using the Drain Plug (if Available)
Many newer Troy-Bilt models, and some older ones, are equipped with a drain plug. This is the most convenient method if your mower has one.
Step-by-Step Guide:
- Safety First! Ensure the engine is completely cool. Never work on a hot engine. Work in a well-ventilated area, away from open flames or sparks. Wear safety glasses and fuel-resistant gloves.
- Locate the Drain Plug: This is usually found at the lowest point of the fuel tank or the carburetor bowl. It might be a small bolt or a screw. Consult your Troy-Bilt owner’s manual if you’re unsure of its exact location.
- Prepare a Container: Place a sturdy, approved fuel container (like a gas can) directly beneath the drain plug. Make sure it’s large enough to hold all the fuel from your tank.
- Loosen the Drain Plug: Using the appropriate wrench or screwdriver, carefully loosen the drain plug. Turn it counter-clockwise. You don’t need to remove it completely, just loosen it enough for fuel to start flowing.
- Drain the Fuel: Allow the fuel to drain completely into your container. This might take a few minutes. You may need to tilt the mower slightly to ensure all the fuel drains out.
- Reinstall the Drain Plug: Once the fuel has stopped draining, carefully retighten the drain plug. Do not overtighten, as this can strip the threads.
- Clean Up: Wipe away any spilled fuel with a rag.
Tips for Using the Drain Plug:
- If the plug is stubborn, a gentle tap with a wrench might help loosen it.
- Have rags handy to catch any drips.
- If your mower has a fuel shut-off valve, close it before loosening the drain plug to prevent fuel from flowing from the tank before you’re ready.
Method 2: Siphoning the Fuel
If your Troy-Bilt mower doesn’t have a drain plug, or if the plug is inaccessible, siphoning is your next best bet. This involves using a hose to draw fuel out of the tank.
What You’ll Need:
- A length of clear, flexible tubing (fuel-grade is best)
- An approved fuel container
- A siphon pump (optional, but makes it easier)
Step-by-Step Guide:
- Safety Precautions: As always, ensure the engine is cool and work in a well-ventilated area away from ignition sources. Wear safety glasses and gloves.
- Position the Mower: Park your mower on a level surface.
- Prepare Your Container: Place your approved fuel container on the ground, lower than the fuel tank.
- Insert the Siphon Tube: Carefully insert one end of the flexible tubing into the fuel tank. Push it down as far as it will go, ideally reaching the bottom of the tank to get as much fuel out as possible.
- Start the Siphon: There are a few ways to start the siphon:
- Manual Siphon (by mouth – use extreme caution!): Place the other end of the tube into your fuel container. Briefly suck on the end of the tube that will go into the container until you see fuel flowing. Immediately remove your mouth from the tube and place it into the container. WARNING: Never swallow fuel. This method carries risks.
- Siphon Pump: If you have a siphon pump, attach it to the end of the tube that will go into the container. Follow the pump’s instructions, which usually involve squeezing the bulb to create suction and start the flow. This is the safer and more efficient method.
- Gravity Feed (if possible): If your fuel tank has a fuel line that can be disconnected and is lower than the container, you might be able to simply disconnect the line and let gravity do the work. This often requires accessing the fuel line near the carburetor.
- Drain the Fuel: Once the siphon is established, fuel will flow into your container. Monitor the flow and remove the tube from the tank when it’s nearly empty to avoid siphoning air.
- Clean Up: Carefully remove the siphon tube and store it for future use. Wipe up any spilled fuel.
Tips for Siphoning:
- Clear tubing allows you to see the fuel flow and know when to stop.
- Ensure the fuel container is stable and won’t tip over.
- If you’re having trouble starting the siphon manually, try submerging the end of the tube that goes into the tank in warm water for a minute; this can make it more pliable.
Method 3: Removing the Fuel Bowl (carburetor Drain)
Some carburetors have a drain screw or plug on the fuel bowl. This is a localized drain, useful for removing the fuel that has accumulated in the bowl, which is often the source of old fuel problems. (See Also: Flat Tire Woes? How to Seal a Lawn Mower Tire Like a Pro)
Step-by-Step Guide:
- Safety First: Engine cool, well-ventilated area, safety glasses, gloves.
- Locate the Carburetor Bowl: This is usually a cup-shaped component at the bottom of the carburetor.
- Identify the Drain Screw/Plug: Look for a small screw or plug at the bottom of the bowl.
- Position Container: Place a small container or rags beneath the drain screw to catch fuel.
- Loosen the Screw: Using the appropriate screwdriver, carefully loosen the drain screw counter-clockwise.
- Drain the Bowl: Allow the fuel in the bowl to drain out.
- Retighten the Screw: Once drained, tighten the screw snugly.
- Clean Up: Wipe any spills.
Important Note:
This method only drains the fuel bowl, not the entire tank. It’s often used in conjunction with other methods or for specific carburetor maintenance.
What to Do with the Drained Fuel
Proper disposal of gasoline is crucial for environmental safety. Never pour it down a drain, into the soil, or into waterways.
- Approved Fuel Container: Store the drained gasoline in an approved, sealed gasoline container.
- Local Hazardous Waste Disposal: The best way to dispose of old gasoline is to take it to your local hazardous waste collection facility or a recycling center that accepts automotive fluids.
- Use It Up (with caution): If the fuel is relatively fresh and you’re just draining for storage, you might be able to use it in another compatible engine (like a generator or leaf blower) later, or mix it with fresh fuel in your car’s gas tank in small quantities (no more than 10-20% old fuel to fresh). However, if the fuel is very old or smells varnish-like, disposal is the safer option.
When to Consider Draining Your Troy-Bilt Mower’s Gas
Beyond seasonal storage, here are other scenarios where draining the fuel is a good idea:
- Buying a Used Mower: If you’re purchasing a pre-owned Troy-Bilt mower, draining the fuel and refilling with fresh gasoline is a wise first step to ensure a clean start.
- Winterizing: This is the most common reason, ensuring your engine components are protected from gumming up over the cold months.
- Selling Your Mower: Emptying the fuel tank before selling can make it easier to transport and safer for the new owner to handle immediately.
- Fuel Contamination: If you suspect water or other contaminants have gotten into your fuel tank, draining is necessary.
