His transmission is skipping out of range, that sounds like it could be a warranty issue to me.

Yes, I strongly suspect the shift fork is bent from somebody attempting to forcibly put the tractor in gear when the gear were not lined up as the problem never happened when I "rattle" the gates once in gear but will happen if the shifter is put in gear and the shifter isn't lightly rattled. The tractor had 7 hours on it when I took delivery and the problem has been there since day one.

Anybody happen to know what diagnostic adaptor Kioti uses on their NXs? I have a bad injector and want to see if the computer happens to know which one using a Launch Pro Touch.

FWIW, the connector on the tractor looks like a Molex 33472-1201 MX150 12-Pin, female, without the two notch tabs on the outer connector.

Hello MinnesotaEric ... did you ever get your Launch Pro Touch working on your Kioti Tractor?
(I realize these posts were years back)

Funny you ask as I just got a new Launch 431 with every adaptor possible but everything came to a grinding halt because I need to first set up an account to fire it up.

The short answer is not yet.

OK ... would like to hear of any success you have...

Cheers!

So it is a no-go for having the correct adaptor. It would be nice if somebody could identify the diagnostic plug Kioti uses. I suspect it is a Delphi engine management system since it uses Delphi injectors.

I think this is a KUM PB625-12027 12-pin plug (Korean mfr) and here is an eBay listing for the F/M pair "KUM 090 Series 12 pins Male Female Waterproof Connector PB625-12027 PB621-12020"(Pardon Our Interruption...). If you Google those part numbers you will find more examples.

I believe the NS and NX series tractors use FT4Scan (password protected) with the Doosan (Bobcat) uVIM. The software for knockoff uVIMs won't have Kioti tractor models but they have a Tier 4 engine selection. Just a thought.

Thanks, I had forgotten about this. The password protection is what prevents communication. Not being a programmer, the password protection has stopped me from pursuing getting the FT4Scan software and the adaptor cable needed to communication with a PC laptop.

All to say, you just reminded me of this thread here on TractorByNet.
