Preparing Your John Deere 100 Series Lawn Mower
Before attempting to start your John Deere 100 series lawn mower, it’s crucial to ensure it’s in optimal condition.
1. Check the Fuel Level
The first step is to ensure your mower has enough fuel.
- Locate the Fuel Tank: The fuel tank is typically located on the side of the mower deck.
- Check the Fuel Level: Look at the fuel gauge or simply glance at the fuel level in the tank.
- Refuel: If the fuel level is low, use a fuel can to refill the tank. Use gasoline recommended by the manufacturer, which will usually be listed in the owner’s manual.
2. Inspect the Spark Plug
The spark plug plays a vital role in igniting the fuel mixture in your mower’s engine.
- Locate the Spark Plug: The spark plug is usually found under a metal cover on the top of the engine.
- Remove the Spark Plug: Use a wrench to remove the spark plug.
- Check the Spark Plug: Look for signs of wear, cracks, or build-up. A new spark plug should be a light tan color.
- Clean or Replace: If the spark plug is dirty or damaged, clean it with a wire brush or replace it with a new one.
3. Ensure the Blades are Sharp
Sharp blades are essential for a clean cut and a healthy lawn.
- Locate the Blades: The blades are located under the mower deck.
- Inspect the Blades: Check the blades for dullness, nicks, or damage.
- Sharpen or Replace: If the blades are dull, sharpen them using a sharpening stone or replace them with new ones.
4. Check the Oil Level
Oil lubricates the engine and prevents it from overheating.
- Locate the Oil Dipstick: The dipstick is typically located on the top of the engine.
- Remove the Dipstick: Remove the dipstick and wipe it clean.
- Check the Oil Level: Insert the dipstick back into the oil fill hole and then remove it again to check the oil level. The oil level should be within the “full” and “low” marks on the dipstick.
- Add Oil: If the oil level is low, add more oil. Use the type and quantity of oil recommended in the owner’s manual.
Starting Your John Deere 100 Series Lawn Mower
Once your John Deere 100 series lawn mower is prepped, it’s time to start the engine.
1. Engage the Safety Features
Before starting the mower, it’s crucial to activate all safety features.
- Check the Blade Engagement Lever: Ensure the blade engagement lever is in the “off” position.
- Confirm the Safety Switch: The safety switch will typically be located on the handle. Make sure it is engaged, which means the handle should be pressed down or in a certain position.
2. Choke the Engine (If Required)
Some John Deere 100 series lawn mowers have a choke lever.
- Locate the Choke Lever: The choke lever is often positioned near the throttle control.
- Choke the Engine: Pull the choke lever out to the full “choke” position. This enriches the fuel mixture to make starting easier, particularly when the engine is cold.
3. Turn the Key (If Applicable)
If your John Deere 100 series lawn mower has an ignition key:
- Locate the Key Ignition: The key ignition is typically located on the control panel.
- Turn the Key to the “Start” Position: Turn the key to the “start” position to engage the starter motor.
- Hold the Key Briefly: Only hold the key in the “start” position for a few seconds.
4. Pull the Recoil Starter (If Applicable)
For lawn mowers without an ignition key:
- Locate the Recoil Starter: The recoil starter is a handle located on the top of the engine.
- Pull the Recoil Starter: Slowly pull the recoil starter cord out until you feel resistance, then pull it quickly and firmly. The engine should start.
5. Release the Choke (If Required)
Once the engine is running, you can release the choke.
- Locate the Choke Lever: Find the choke lever, as explained earlier.
- Gradually Release the Choke: Slowly push the choke lever back into the “run” position. This allows the engine to run more smoothly.
6. Engage the Blades
Once the engine is warmed up, you can engage the blades.
- Locate the Blade Engagement Lever: Find the blade engagement lever, typically located near the throttle control.
- Move the Lever to the “On” Position: Move the blade engagement lever to the “on” position to engage the blades.
Troubleshooting Starting Problems
Even with proper preparation, you might encounter difficulties starting your John Deere 100 series lawn mower. Here are some common starting problems and how to address them.
1. The Engine Won’t Turn Over
If the engine isn’t even turning over, it likely means there’s a problem with the starter system.
- Check the Battery (If Applicable): If your mower has an electric start, check the battery to ensure it’s charged.
- Check the Starter Cord (If Applicable): Make sure the recoil starter cord isn’t jammed or broken.
- Check the Spark Plug: Remove the spark plug and inspect it for wear, cracks, or build-up. If it’s faulty, replace it.
2. The Engine Turns Over but Won’t Start
If the engine turns over but won’t start, it could be a problem with the fuel system or the ignition system.
- Check the Fuel Level: Ensure the fuel tank is full and there’s no blockage in the fuel line.
- Check the Air Filter: A clogged air filter can restrict airflow and prevent the engine from starting.
- Check the Spark Plug: Remove the spark plug and test it using a spark plug tester. If it’s not sparking, replace it.
3. The Engine Starts but Dies Immediately
If the engine starts but dies immediately, it could be a problem with the fuel system or the ignition system.
- Check the Fuel Line: Ensure the fuel line isn’t kinked or blocked.
- Check the Spark Plug: Remove the spark plug and inspect it for wear, cracks, or build-up.
- Check the Carburetor: A dirty or clogged carburetor can prevent the engine from getting enough fuel.
