Well, I ordered the complete set of repair manuals off ebay. Talked to a dealer that is 95 miles away and they have the diagnostic equipment. $800 transport for them to come pick it up. I talked to the local dealer again and he's going to talk to the factory rep and see if something else can be done. Called Kubota and JD and they said there machines won't work even with the right cable (thought about buying the adapter). I am still stuck. I will never buy another tractor with electric shuttle again unless they have the diagnostic equipment locally. I looked at MF 4610 and it has all the electronics, but they have the computers to work on them. Unfortunately, turf tires are not an option on the MF. Bought a 5470 MF last year, but it's way too big for what I need at home/church. The TN75S is perfect for me if I could get the electrics to work properly. I use it to cut 30 acres weekly at the church and the galaxy tires work great and don't tear up the turf. $4500 to buy my own electro-diagnostic machine is not really an option.
