Engaging the Choke
The choke is a critical component that helps your John Deere lawn mower start, especially in cold weather. When engaged, the choke restricts airflow into the engine, which enriches the fuel mixture, making it easier to ignite.
Here’s how to engage the choke:
- Locate the choke lever: It’s typically a lever or button on the engine or handlebars.
- Engage the choke: Push or pull the choke lever to the “choke” position. You’ll usually hear a click or feel the lever engage.
Priming the Carburetor (If Applicable)
Some John Deere lawn mower models have a priming bulb on the carburetor. This bulb helps to manually introduce fuel into the carburetor, making starting easier.
Priming Procedure
- Locate the priming bulb: It’s usually a small, round bulb near the carburetor.
- Prime the carburetor: Press the bulb several times (usually 4-6 times) to fill the carburetor with fuel.
Starting the Engine
Now that your John Deere lawn mower is prepared, it’s time to crank it.
Starting Procedures:
- Engage the blade clutch (if applicable): This prevents the blades from spinning while you’re starting the engine.
- Turn the ignition key to the “start” position: This activates the starter motor.
- Release the ignition key: Once the engine starts, release the ignition key to the “run” position.
Disengaging the Choke
Once the engine is running, you’ll need to disengage the choke. This allows more air into the engine, preventing it from stalling.
Disengaging the Choke
- Locate the choke lever: It’s the same lever you engaged earlier.
- Disengage the choke: Push or pull the lever back to the “run” position.
Troubleshooting Common Starting Issues
Even after following these steps, you may encounter difficulty starting your John Deere lawn mower. Here are some common starting issues and how to troubleshoot them:
The Engine Doesn’t Turn Over
- Dead Battery: A dead battery will prevent the starter motor from turning. Check the battery voltage and charge or replace it if necessary.
- Loose or Corroded Battery Terminals: Corrosion or loose battery terminals can impede the flow of current. Clean the terminals and tighten any loose connections.
- Faulty Ignition Switch: A faulty ignition switch won’t allow power to reach the starter motor. Try replacing the switch if it’s damaged.
The Engine Turns Over But Won’t Start
- No Fuel: Check your fuel level and ensure the fuel line isn’t kinked or blocked.
- Bad Spark Plug: A worn, fouled, or damaged spark plug won’t create a spark. Inspect the spark plug and replace it if needed.
- Clogged Carburetor: A clogged carburetor prevents fuel from flowing properly. Clean or rebuild the carburetor if necessary.
The Engine Starts But Stalls Immediately
- Choke Engaged: Make sure you’ve disengaged the choke after the engine starts.
- Fuel Problems: An empty fuel tank, a blocked fuel line, or bad fuel can cause stalling. Check your fuel supply and consider draining and replacing old fuel.
- Air Leak: An air leak in the intake manifold or carburetor can cause the engine to run poorly and stall. Inspect for leaks and seal them if necessary.
Essential Safety Tips
- Wear eye protection: Avoid flying debris and other hazards.
- Use proper clothing: Wear sturdy shoes, long pants, and gloves to protect yourself.
- Keep a safe distance: Don’t stand directly in front of the mower when starting it.
- Follow manufacturer’s instructions: Always refer to your John Deere lawn mower’s user manual for specific operating procedures and safety guidelines.
