It’s been sitting dormant all winter, and you’re not sure how to get it roaring back to life. Don’t worry, you’re not alone. Many homeowners face the same challenge when trying to wake up their old riding lawn mowers. This article will guide you through the process, step-by-step, equipping you with the knowledge and tips to get your mower running smoothly. We’ll cover everything from pre-start checks to troubleshooting common issues, so you can get back to enjoying a perfectly manicured lawn in no time.
Overview
Starting an old riding lawn mower is a straightforward process with a few key steps. The first is to prepare the mower for a successful start by performing pre-start checks. This includes ensuring sufficient fuel, a clean air filter, and proper oil levels. Next, you’ll need to prime the engine, if necessary, and follow the correct starting procedures. If your mower fails to start, there are several troubleshooting steps you can take to identify and rectify the problem. This might involve checking the spark plug, fuel system, and other potential culprits.
Pre-Start Checks: Setting the Stage for Success
Before you even think about turning the key, take some time to perform a few essential pre-start checks. These simple steps will ensure your mower is ready to fire up and will save you potential headaches down the line.
1. Fuel Up:
The first step is to check your fuel supply. If your mower has been sitting for a while, the fuel might have gone stale or become contaminated. Here’s what you should do:
- Check the fuel level: Ensure you have enough fuel to start the mower. The fuel tank should be at least partially full.
- Inspect the fuel: If the fuel is older than a few months, it’s best to drain it and replace it with fresh, high-octane gasoline.
- Add fuel stabilizer: If you’re storing the mower for an extended period, add a fuel stabilizer to the tank to prevent the fuel from degrading.
2. Air Filter Inspection: Breathe Easy
A clogged air filter can choke the engine and prevent it from starting. Follow these steps to check your air filter:
- Locate the air filter: The air filter is typically located in a housing near the engine.
- Inspect the filter: Remove the filter and check its condition. If it’s dirty or clogged, replace it with a new one.
- Clean the air filter housing: Use a vacuum cleaner with a brush attachment to remove any debris from the air filter housing.
3. Oil Check: Lubricate for Longevity
Ensure your mower has enough oil to lubricate the engine. Check the oil level using the dipstick:
- Locate the dipstick: The dipstick is usually located on the engine block.
- Check the oil level: Pull out the dipstick, wipe it clean, and re-insert it fully. Then, remove it again and check the oil level. It should be between the “full” and “low” marks on the dipstick.
- Add oil if needed: If the oil level is low, add the appropriate type of oil for your mower, as specified in the owner’s manual.
Starting Procedures: Bringing Your Mower to Life
Once you’ve completed the pre-start checks, you’re ready to attempt to start your mower. Follow these steps carefully:
1. Prime the Engine (If Necessary):
Some riding lawn mowers have a primer bulb that helps to get fuel into the carburetor. This is especially helpful for mowers that have been sitting for a long time.
- Locate the primer bulb: The primer bulb is usually located on the carburetor or near the fuel line.
- Prime the engine: Press the primer bulb a few times to fill the carburetor with fuel.
2. Start the Mower:
Now, it’s time to turn the key and see if your mower comes to life. Follow these steps:
- Engage the choke: Some mowers have a choke lever or button. Engage the choke by pulling it out or pushing it in, depending on your model.
- Turn the key: Turn the ignition key to the “start” position.
- Release the choke: Once the engine starts, slowly release the choke. If the engine stalls, try engaging the choke again and restarting the mower.
Troubleshooting Common Starting Issues
If your riding lawn mower refuses to start, don’t panic. There are a few common reasons why your mower might be playing hard to get. Let’s explore some of the most likely culprits:
1. The Spark Plug: The Heart of Ignition
A faulty spark plug is a common culprit for a no-start condition. To check your spark plug:
- Locate the spark plug: The spark plug is usually located on the top of the engine.
- Remove the spark plug: Use a spark plug socket and wrench to remove the spark plug.
- Inspect the spark plug: Examine the spark plug for signs of wear, damage, or fouling.
- Test the spark plug: If possible, use a spark plug tester to verify that the spark plug is producing a spark.
- Replace the spark plug: If the spark plug is faulty, replace it with a new one that matches the specifications in your mower’s manual.
2. The Fuel System: Delivering the Power
A problem with the fuel system can also prevent your mower from starting. Here’s how to check it:
- Inspect the fuel lines: Check the fuel lines for any cracks, leaks, or blockages.
- Clean the carburetor: If the carburetor is dirty or clogged, it can prevent fuel from reaching the engine. A carburetor cleaning kit is readily available and can be used to clean the carburetor thoroughly.
- Replace the fuel filter: The fuel filter can become clogged over time, restricting fuel flow. Replace it with a new filter if necessary.
3. The Battery: Providing the Electrical Spark
A weak or dead battery can also prevent your mower from starting. Here’s how to check it:
- Check the battery terminals: Ensure the battery terminals are clean and free of corrosion.
- Test the battery: Use a voltmeter or battery tester to check the battery’s voltage.
- Replace the battery: If the battery is dead or weak, replace it with a new one that matches the specifications in your mower’s manual.
Get Your Mower Back in Shape
Starting an old riding lawn mower might seem daunting, but it’s a manageable process. By following these steps, you can confidently get your mower running again and enjoy a well-manicured lawn. Remember to perform regular maintenance, store the mower properly, and don’t hesitate to consult your owner’s manual or a qualified mechanic for any issues you cannot resolve.
