The warm sun is shining, the birds are singing, and your lawn is… well, it’s not looking its best. It’s time to get the lawnmower out and tackle that overgrown patch, but there’s a problem. You pull the cord, and… nothing. Your lawnmower refuses to start. Frustrating, right? This guide will break down the simple steps involved in pulling the cord on a lawnmower, helping you troubleshoot common problems and get your mower running smoothly in no time. From basic techniques to advanced tips, we’ll cover everything you need to know to master the art of the lawnmower pull.
A Quick Overview of Pulling a Lawn Mower Cord
Pulling the cord on a lawnmower is a crucial step in starting the engine. It engages the starter mechanism, which in turn, sets the engine in motion. There’s more to it than just a quick yank, though. You need to use the right technique to ensure the engine gets enough force to start. Here are the basic steps:
- Prepare: Make sure the lawnmower is on a flat surface, the choke is engaged (if necessary), and the fuel tank is full.
- Hold the cord handle: Grip the cord handle firmly and hold it securely.
- Pull slowly: Start by pulling the cord slowly, feeling for any resistance.
- Pull sharply: Once you feel resistance, pull the cord sharply and forcefully.
- Release and repeat: If the engine doesn’t start, release the cord and pull again, repeating the process until the engine starts.
Now, let’s delve into each stage in detail, covering common problems and how to fix them.
Understanding the Lawn Mower Starting Mechanism
Before diving into the steps, it’s important to understand how the pull cord works. The cord is attached to a recoil starter mechanism, which houses a spring-loaded rope. When you pull the cord, you stretch the spring, storing energy. This stored energy is then released, turning the engine crankshaft and starting the combustion cycle.
Step 1: Prepping the Lawn Mower
A little preparation can make a big difference when starting your lawnmower. Here’s what you need to do:
- Check the fuel level: Ensure that your fuel tank is full, or at least has enough fuel to get you through your mowing session.
- Position the mower: Place your lawnmower on a flat, stable surface. This ensures the starter mechanism operates smoothly and prevents accidental tipping.
- Engage the choke (if necessary): Many lawnmowers have a choke, which controls the air intake. Engaging the choke enriches the fuel mixture, making it easier to start the engine, especially when it’s cold.
Step 2: Holding the Cord Handle
Holding the cord handle correctly is crucial for efficient pulling. Here’s how to do it:
- Firm grip: Grip the cord handle firmly, using your thumb and fingers to create a strong hold.
- Proper positioning: Position your hand so that the cord runs between your thumb and index finger, with your remaining fingers wrapped around the handle. This gives you good leverage for pulling the cord.
- Avoid sudden movements: Hold the handle steadily. Avoid jerking or sudden movements that can lead to injuries or damage to the recoil mechanism.
Step 3: Pulling the Cord Slowly
The initial pull is about feeling for resistance, not starting the engine. Here’s the process:
- Slow and steady: Pull the cord slowly and steadily until you feel resistance. This indicates the spring is winding and storing energy.
- Avoid overstretching: Don’t pull the cord too far before feeling resistance. Overstretching the spring can damage the recoil mechanism.
Step 4: Pulling the Cord Sharply
This is the part where you actually start the engine. Here’s what to do:
- Sharp and forceful: Once you feel resistance, pull the cord sharply and forcefully. The aim is to release the stored energy quickly and efficiently.
- Follow through: Continue pulling the cord all the way out, even after you feel the engine start. This ensures that the engine has enough momentum to run smoothly.
Step 5: Releasing and Repeating
If the engine doesn’t start on the first pull, don’t panic! Here’s what you should do:
- Release the cord: Allow the cord to rewind slowly. Avoid jerking it back in.
- Repeat steps 3 and 4: Repeat the process of pulling the cord slowly, feeling for resistance, and then pulling sharply.
- Be patient: It may take several pulls to get the engine started.
Common Problems and Troubleshooting
Sometimes, even with the right technique, your lawnmower might refuse to start. Here are some common problems and how to troubleshoot them:
1. Dead Battery (Electric Start Mower):
- Problem: If your lawnmower has an electric start, a dead battery can prevent it from starting.
- Solution: Check the battery terminals for corrosion, clean them if necessary, and charge the battery.
2. Flooded Engine:
- Problem: This happens when too much fuel is injected into the engine, causing it to “drown” and refuse to start.
- Solution: Remove the spark plug, crank the engine a few times to clear out the excess fuel, and then reinstall the spark plug.
3. Clogged Air Filter:
- Problem: A clogged air filter restricts airflow to the engine, making it difficult to start.
- Solution: Clean or replace the air filter according to the manufacturer’s instructions.
4. Stuck Choke:
- Problem: If the choke is stuck in the “on” position, it can prevent the engine from getting enough air to start.
- Solution: Check the choke lever, make sure it’s free and can move easily, and try starting the mower with the choke in the “off” position.
5. Bad Spark Plug:
- Problem: A faulty spark plug can prevent the engine from igniting the fuel-air mixture.
- Solution: Remove the spark plug, inspect it for wear or damage, and replace it if necessary.
6. Low Fuel Level:
- Problem: If your lawnmower is out of gas, it won’t start!
- Solution: Fill the fuel tank with fresh, clean gasoline.
Tips for Pulling the Cord Successfully
- Keep your fingers clear: Make sure your fingers are clear of the cord handle before pulling. This prevents injuries if the cord recoils unexpectedly.
- Don’t force it: If the engine feels unusually stiff or difficult to pull, stop and investigate. There may be a mechanical issue that needs attention.
- Use gloves: Wearing gloves can provide a better grip and protect your hands from blisters or calluses.
- Warm up the engine: If you’re having trouble starting your lawnmower, try warming up the engine by spraying a little starting fluid into the carburetor.
- Seek professional help: If you’ve tried all the basic troubleshooting steps and your lawnmower still won’t start, it’s time to call a professional mechanic.
Conclusion: Mastering the Art of the Pull
Pulling the cord on a lawnmower is a simple but crucial skill. With a little practice and understanding of the starting mechanism, you’ll be able to confidently start your mower and tackle those overgrown patches with ease. Remember, always prioritize safety and follow the manufacturer’s instructions. And if you’re ever in doubt, don’t hesitate to seek professional help. Happy mowing!
