- Wear gloves: Gloves will protect your hands from the battery acid and provide better grip.
- Never smoke around a battery: Battery fumes are flammable.
- Ensure the mower is on a level surface: This helps prevent the mower from rolling during the jump-start.
- Disconnect the mower’s spark plug wire: This prevents accidental starting during the jump-start process.
- Ensure the jump cables are in good condition: Look for any cracks or damage to the cables.
Gathering Your Equipment
You’ll need the following items to jump-start your John Deere lawn mower:
- A fully charged battery: This is the “donor” battery that will provide the temporary power boost. A car battery is usually sufficient.
- Jump cables: Make sure the cables are rated for the amperage of your mower’s battery.
- A wrench: This is for loosening and tightening battery terminals.
The Jump-Start Process: Step by Step
- Locate the batteries: The John Deere lawn mower battery is typically located under the seat, in a compartment near the engine, or on the side of the chassis. The donor battery is usually in your car.
- Connect the Positive Cables: Connect the red (positive) cable to the positive (+) terminal of the discharged mower battery. Then, connect the other end of the red cable to the positive terminal of the donor battery.
- Connect the Negative Cables: Connect the black (negative) cable to the negative (-) terminal of the donor battery. Important: Connect the other end of the black cable to a clean, unpainted metal surface on the mower frame, not to the negative terminal of the discharged battery.
- Start the Donor Battery: Start the car or other vehicle with the good battery. Allow it to run for a few minutes to ensure a sufficient charge transfer.
- Try Starting the Mower: Attempt to start the lawn mower. If it doesn’t start immediately, try again after a few minutes.
- Disconnect the Cables: Once the mower starts, disconnect the cables in reverse order. Begin by removing the black cable from the mower frame, then remove the black cable from the donor battery, followed by the red cable from the donor battery, and finally the red cable from the mower battery.
- Run the Mower: Let the mower run for at least 15 minutes to allow the battery to recharge.
Troubleshooting Common Problems
If your mower still won’t start after a jump-start, there could be other underlying issues:
1. Battery Issues:
- Dead battery: If the jump-start fails to revive the mower, the battery might be completely dead and require replacement.
- Faulty battery terminals: Corrosion on the battery terminals can hinder electrical flow. Clean them with a wire brush and baking soda solution.
2. Ignition System Problems:
- Spark plug: A fouled or damaged spark plug can prevent the engine from starting. Inspect and replace the spark plug if necessary.
- Ignition coil: A faulty ignition coil can fail to deliver the spark needed to ignite the fuel.
3. Fuel System Problems:
- Empty fuel tank: Check the fuel level and add fuel if necessary.
- Old or bad fuel: Old fuel can gum up the carburetor and prevent the engine from starting. Drain and replace the fuel with fresh, high-octane gasoline.
Keeping Your John Deere Battery Healthy: Tips & Tricks
- Charge Regularly: A fully charged battery will last longer. Charge the battery every few months, especially if it’s not being used regularly.
- Use a Battery Tender: A battery tender is a device that keeps your battery trickle-charged, preventing deep discharge.
- Store Properly: Store your mower in a cool, dry place during the off-season. A battery left outdoors in extreme temperatures can degrade quickly.
- Inspect Battery Terminals: Regularly inspect the battery terminals for corrosion. Clean them with a wire brush and baking soda solution to maintain good electrical conductivity.
Final Thoughts
