JD 3720 Cold Start Issues

Wonder if your key switch could be a problem?
Also agree on the manual.
Possibly one of the safety switches not letting it crank too.

It's at the dealer and they thought they can get to it monday. Will post what they find when I go pick it up.

Hopefully it's not something as simple as the PTO switch being ON. I've had similar experience with my 3720 and found the PTO switch only needed pushed in to the OFF position for the engine to start.

Update: I picked the 3720 up from the dealer this morning. Only took an hour or so at the shop and its back to starting perfectly. That's the good news. The puzzling part is that the mechanic reported that a 10 amp fuse was missing from the fuse box and that was the reason it was showing the Error Code 57 and would not start??
I looked at the fuse box and he stuck a 10 amp fuse in the F2 slot. Amazingly enough is when I look at the manual, it shows this to be blank for a non-cab tractor! I didn't know this at the time or I would have questioned them about it. In any event, the tractor starts, the error codes have been cleared, and I have a $241 ten amp fuse installed!!
On one hand if this is truly the solution, I could kick myself for not sticking a 50 cent fuse in the panel, but on the other hand, how could I now based on the info the manual provided??

Maybe pull that fuse out and see if it'll still crank? That'll confirm whether the manual is right or the mechanic was.

Manuals can have errors in them... and do.

Mechanics can have brain farts too.

As I suspected, tractor would not start after I got it back home. Called the dealer and he came out and looked again. Not sure what it might be. Could be in the instrument panel he thinks...I hate to pay them another large sum to change the panel out plus $600 for a panel that seems to work. Looks like a short to me in a wire somewhere.

Have you triple checked all the safety switches ? I know you may have done so but this sounds like something you could handle....as you say, hate to spend more $$$ green on the green.
.keep us posted

Latest update: pulled the tractor into a 75 degree shop and after sitting three hours, starts and runs fine. Eliminates Wiring issues, could it be the dash? Going to remove instrument panel and leave outside overnight then reinstall and see what happens.

You don't have your location in your bio (that would help !! ) so we don't relate well to what country or area you are dealing with, as far as temp, etc.

A 75 deg shop is way too hot for me, even if sitting around for long periods of time. Let alone, having to move around... I'd be shedding a lot of clothes.
