  • Engage the choke: Push the choke lever to the fully engaged position.

2. Prime the Engine: A Boost for Cold Starts

Priming the engine adds extra fuel to the carburetor, aiding in a quicker start, particularly on cold days.

  • Locate the primer bulb: It’s typically positioned on the carburetor and often has a red or yellow bulb.
  • Prime the engine: Repeatedly press the primer bulb several times until you see fuel flowing.

3. The Initial Pull: Getting the Engine Going

Now it’s time to give the starter rope a good pull.

  • Locate the starter rope: It’s usually positioned on the top of the engine.
  • Pull the starter rope: Slowly pull the starter rope until you feel resistance. Then give it a firm, quick pull.
  • Don’t pull the rope too far: This can damage the engine.

4. Disengage the Choke: Letting the Engine Breathe

Once the engine starts, you need to disengage the choke to allow the engine to run properly.

  • Locate the choke lever:
  • Disengage the choke: Gently push the choke lever back to the disengaged position.

Troubleshooting Common Starting Issues: Addressing Roadblocks

Even with proper preparation, starting a John Deere push mower can sometimes be tricky. Here are some common issues and solutions:

1. Engine Not Turning Over: Diagnosing the Problem

If the engine doesn’t turn over, it means there’s an issue with the starter system.

  • Check the spark plug: A fouled spark plug can prevent the engine from igniting. Replace it if necessary.
  • Ensure the starter rope is properly wound: If the rope isn’t wound correctly, it won’t engage with the starter mechanism.
  • Inspect the starter assembly: Look for any signs of damage or wear in the starter mechanism.

2. Engine Starts But Dies Immediately: Finding the Culprit

This issue usually indicates a problem with the fuel system or the spark plug.

  • Check the fuel tank: Ensure there’s enough fuel in the tank.
  • Inspect the fuel lines: Look for any kinks or blockages in the fuel lines.
  • Check the spark plug: A worn or fouled spark plug can cause the engine to start and die immediately.

3. Engine Starts But Runs Rough: Adjusting the Mixture

A rough-running engine indicates a fuel-air mixture problem.

  • Adjust the carburetor: Many John Deere push mowers have an adjustable carburetor. Refer to your owner’s manual for instructions on adjusting the mixture screws.
  • Clean the carburetor: A dirty carburetor can prevent the fuel from flowing correctly. Cleaning it can resolve the issue.

4. Engine Starts But Won’t Run at Full Speed: A Power Struggle

If your engine starts but doesn’t run at full speed, there could be a few culprits.

  • Check the air filter: A clogged air filter restricts airflow, limiting engine power.
  • Inspect the fuel lines: Make sure there are no kinks or blockages preventing fuel from flowing freely.
