Engine Problems:
If your John Deere lawnmower is having trouble starting or running smoothly, a reset might be the answer. The reset process can clear temporary glitches in the ignition system, which can sometimes prevent the engine from starting properly.

Step 2: Wait for a Few Minutes
Wait for at least 5-10 minutes to allow the electrical system to completely discharge.
Step 3: Reconnect the Battery
Reconnect the battery terminals, making sure to attach the positive terminal (red wire) first followed by the negative terminal (black wire).
Step 4: Test the Engine
After reconnecting the battery, try starting the engine. If the reset was successful, the engine should start and run smoothly.
