My L3410, 4wd tractor will not start. In recent months, I have replaced the battery, the ignition switch, all new battery cables. I get lights on the dashboard. And the fuel solenoid rocker works when I turn the key. But other than that...it is dead. No click. No turn over. Nothing. I was on it all morning this morning. Parked it. Went back out later in the day....dead. This has happened before. Thus the reason for replacing the ignition switch. I am wondering if there is an issue with the neutral safety "switch" somewhere. Both GST lever on the left side of the steering column, and the transmission gear/speed selector lever at the left side of the seat are in neutral. I have jee-hawed with them to see if there would be any "catch." Still nothing. I am open to any and all ideas.
