How to Check the Lawn Mower Battery

Here is a step-by-step instruction on how to check the battery if your Toro Lawn Mower won’t start:

1. Safety first: Ensure that the ignition key is removed from the mower and the spark plug wire is disconnected to prevent accidental starts.
2. Locate the battery: The battery is typically located under the hood or near the engine. Refer to your Toro Lawn Mower’s user manual for the specific location.
3. Inspect the battery: Check for any signs of physical damage, such as cracks, leaks, or corrosion on the battery terminals. Corrosion appears as a white or greenish substance on the terminals.
4. Clean the battery terminals: If there is corrosion present, mix a solution of baking soda and water to create a paste. Apply the paste to the terminals and use a wire brush to scrub away the corrosion. Rinse the terminals with clean water and dry them thoroughly.
5. Check the battery voltage: Using a multimeter, set it to the DC voltage setting and connect the red probe to the positive terminal (+) of the battery and the black probe to the negative terminal (-). Check the voltage reading. A fully charged battery should typically read around 12.6 volts or higher. If the voltage is significantly lower, it may indicate a weak or discharged battery.
6. Charge or replace the battery: If the battery voltage is low, charge the battery using an appropriate battery charger. Follow the manufacturer’s instructions for charging. If the battery fails to hold a charge or if the voltage is consistently low even after charging, it may be necessary to replace the battery with a new one.
7. Reinstall the battery: Once the battery is fully charged or replaced, re-install it in the mower and ensure that the terminals are securely tightened.
8. Reconnect the spark plug wire: Reconnect the spark plug wire to the spark plug.
9. Attempt to start the mower: Turn the ignition key and try starting the mower. If the battery was the issue, it should now start successfully.

If the mower still doesn’t start after checking the battery, you may need to further troubleshoot other components such as the spark plug, fuel system, or ignition system. Refer to the Toro Lawn Mower’s user manual or consult a professional for additional troubleshooting steps.
