    Bought a New L3902, turned out to be a 2019

    This is weird. They OP has not posted anything since Nov 23rd. I've had a dealer do a bait and switch on me, (not a tractor, but parts) so I'm curious as to what happened with this case.

    John Deere 790 stuck in the middle of the field, dead, won't stay running.

    THANKS TO EVERYONE WHO HAS POSTED! Lots of good info. I have a pretty good idea now where and how to deal with this. That wiring diagram really helped and I agree it's fuel and safety/sensor/switch issue. Now I just gotta fine which one(s). ;-) I can only work on it on the weekend right now...

    John Deere 790 stuck in the middle of the field, dead, won't stay running.

    Thanks for the wiring diagram!!! Really helpful. First thing I did was go to the seat switch and what do I see? It goes to something called a "time delay control module." Great. What the heck is that? It goes to both the seat switch and the fuel relay. Anytime I read "timing" and "delay" and...

    John Deere 790 stuck in the middle of the field, dead, won't stay running.

    Regarding the seat sensor. It's a 4 wire, all molded together. I took it apart. It has 3 positions: 1. no one on the seat, nothing is engaged. Open circuit. 2. someone on the seat. The two outside wires are shorted/connnected, closed circuit on the two outside wires. 3. Pull on the switch and...

    John Deere 790 stuck in the middle of the field, dead, won't stay running.

    Okay I am 99% sure I'm battling two issues. Tried to start it today. Started from square one. Everything in neutral, PTO disengaged, hi/low in neutral. Would not start. Rowed thru the gears put it back on neutral, rechecked PTO, rechecked hi/low. Even cycled the throttle a few times. Turn the...

    John Deere 790 stuck in the middle of the field, dead, won't stay running.

    The problem is actually two fold. #1. just to get it started is a hit or miss. Right now it won't even start regardless of anything I do... then randomly it'll just start like nothing was ever wrong. So that's part one. #2. Once I do get it started it runs great. Until I try to engage...

    John Deere 790 stuck in the middle of the field, dead, won't stay running.

    I'm out in the sticks. At least an hour away from anything like a JD dealship but Monday i'll call one and see what I can get. I'm just shocked it's not available online. There are a zillion people searching for John Deere safety switch but very little information and none on the version I have...

    John Deere 790 stuck in the middle of the field, dead, won't stay running.

    If i knew were all the safety switches were and have a wiring diagram that's exactly what I'd be doing. But so far I can't find that information online.

    John Deere 790 stuck in the middle of the field, dead, won't stay running.

    Bought a used 2006 790 with 600 hours on it. It worked at first fine. But then I started having troubles. Initially it was the seat switch. So I fixed that. But today it just kept dying. I thought it was the seat switch again so I bypassed it. Okay, once I did that it would start. But the moment...
