Thanks a lot for the info. I'll do some more troubleshooting now that the weather has improved. I'll let you know what I find. Kent.

Kent, please take a look at this post, thread #7.

I found the problem finally- a blown fuse. My fuse panel is different from the one shown in my manual. I finally found the problem- sure enough, it was the thermistor in the thermostat housing blowing the fuse. My fuse panel is different from the one shown in my manual; the top row has six fuses, the next row three fuses, then a row of six relays, then four spare fuses at the bottom. The middle fuse in the second row was blown but it was not immediately obvious, because the blow was at the side of the fuse, not the middle where you would normally look. I unplugged the thermistor, replaced the fuse, and the tractor now starts. It blows a little white smoke instead of black now on startup,but runs fine. Thanks everyone for your much-appreciated suggestions and diagrams! Kent.

Thanks for letting us know you got it fixed, what you found and describing your fuse panel. Even though you are in FL, I would suggest you replace the sensor as the cold advance circuit is used when the coolant temperature is under 122 F. This comes from JD manual CTM125 for the 3029 engine. This could be the reason for the white smoke.

I had some smoke from my engine and I started using JD summer fuel conditioner TY26784 and winter fuel conditioner and after a few tanks no more smoke and even after the tractor seats for up to two weeks it literally starts with just the flick of the key.

Thanks for the info. Before I had this problem the tractor would belch out a bunch of black smoke on every cold start; I'll replace the switch and try the conditioner. Kent
