I have tried everything new battery , tested starter , new solenoid and ignition switch still wont turn over at all.
Since this is your first rider, you have to be seated on the mower seat before it will start. The seat switch is under your seat. If you get off without setting the clutch and then the brake, it will cut off.. next check battery connection. They get loose over time. As everyone else said make you are not trying to start it with the blades engaged.. Here's one for the future you may run into. The belt comes off and you remove the deck belt cover and maybe you bend the belt tensioner belt keeper to get the belt back on,,,,, not a good thing. It's best to use a 9/16 open wrench and loosen but not all the way, just enough to raise the tension pulley to get the belt back on and then retighten. I tried twice to force the belt into the tension pulley and finally figured out that was a mistake.
