2015 John Deere 5075

[Bandit60]

John Deere 5075 maybe 425 hours broke down in the field on Saturday. Display said NEUTRAL. Transmission disengaged. Walked back to barn. Any ideas ?

Maybe some more info would help. Not sure what "broke down" really means.

What it means is the computer decided the shuttle should go to neutral. (for whatever reason) When that happens you walk home.

Thats exactly what I had to do. The tractor simply went into neutral for some reason. Dealership here said "check" for a disconnected wire under the tractor and check fuses". I have done these things. Fuses are good and didn't see any broken wires.

Okay, so you've done the easy, quick, once over. Now it's time to get serious (and your wallet out). That means you get the "Deere people" (or maybe if you're lucky, someone else that knows the system and has the necessary tech savvy and equipment to trouble shoot it) involved to figure out WHY the computer doesn't like what it sees. Possibilities are many, and no one out here can tell you which one is most likely. Computer controlled transmissions are great when they work, but not so much when they don't. Self experimenting isn't cheap either. The various pressure switches, sensors, solenoid coils, ETC can be crazy expensive.

I would ohm out those wires from end to end and not just a visual inspection...

That's a great idea if you know which wires to "ohm out". There's only a mile of wires in there, and you need to get to both ends of each to "ohm" them out.

Pretty sure that's what wiring schematics are for....

I guess you work on these all the time, right?

I work on a lot of stuff all the time.
