Tools and Materials
Here’s what you’ll need before you begin:
- A working battery: This can be from another car, truck, or even a larger riding mower.
- Jumper cables: Look for heavy-duty cables with insulated clamps.
- Safety glasses: Protect your eyes from potential sparks or battery acid.
- Gloves: Protect your hands from potential battery acid.
Safety Precautions
- Always wear safety glasses and gloves.
- Never smoke or have any open flames near the battery.
- Never touch the positive and negative terminals of the battery at the same time.
- Disconnect the battery from the mower before disconnecting the jumper cables.
Jumpstarting Your John Deere Riding Mower
- Locate the Battery: The battery on your John Deere riding mower is typically located under the seat or near the engine. Refer to your owner’s manual for the exact location.
- Connect the Jumper Cables:
- Positive (Red) Cable: Connect the red clamp to the positive (+) terminal of the dead battery on your John Deere mower.
- Positive (Red) Cable: Connect the other red clamp to the positive (+) terminal of the working battery.
- Negative (Black) Cable: Connect the black clamp to the negative (-) terminal of the working battery.
- Negative (Black) Cable: Connect the other black clamp to a metal grounding point on the frame of the John Deere mower. Important: Never connect the black clamp to the negative terminal of the dead battery. This can cause sparks and damage the battery or electrical system.
- Start the Working Vehicle: Start the vehicle with the working battery and let it run for a few minutes. This will allow the battery to charge.
- Start the John Deere Mower: Try starting your John Deere mower. If it doesn’t start right away, try giving it some gas and revving the engine.
- Disconnect the Jumper Cables: Once the mower is running, carefully disconnect the jumper cables in reverse order. Start by disconnecting the black clamp from the mower’s frame, then the black clamp from the working battery. Next, disconnect the red clamp from the working battery, then finally disconnect the red clamp from the dead battery on the mower.
Troubleshooting
If your John Deere riding mower still won’t start after jumpstarting, consider these additional troubleshooting steps:
- Check the Battery Connections: Ensure the battery terminals are clean and tightly connected. Corroded terminals can prevent proper electrical flow.
- Check the Starter: If the starter motor isn’t engaging, it may be faulty. This can be checked by tapping on the starter motor with a hammer while the ignition is turned on. Be careful not to hit the motor too hard.
- Check the Spark Plugs: If the spark plugs are fouled or damaged, they can prevent the engine from starting. Replace the spark plugs if necessary.
- Check for Fuel Issues: If the mower isn’t getting fuel, there may be a problem with the fuel lines, fuel pump, or carburetor.
- Check the Fuel Switch: Make sure the fuel switch is in the “on” position.
- Check the Choke: If the choke is not properly engaged, it can prevent the engine from starting.
- Inspect the Battery: If the battery is old or damaged, it may need to be replaced.
