My John Deere Z225 is having some starting issues. Sometimes it starts up right away with no issues. However, I often just get a click sound when I turn the key. If you keep trying eventually it will start. The battery / charge is not the issue. The 1st time it happened I just put a new one in and same problem. If you do the screw driver trick on the solenoid, the motor will turn over but not fire. Maybe a dead spot on the starter?
Thanks...
