I do get a flashing code rapid and 8 slow a pause and 1 more
Greetings and welcome to TractorByNet. :tractor:
Do you get a symbol flashing in a pattern? If so. It might flash several times very fast then pause flash X amount of times slower. Pause, then flash X amount of times slower. The fast flashes is the alert, and the next sets are the actual codes. I actually found this information here on this site dated 2010 thru a Google search. If no response here, try to Google the information thru their search. "TN75S error code tractor does not move" without quotes. Knowing the error codes, is the key to find out what is going on.
Sometimes answers are not right away here and may take a day or two for someone in the know to see it. Brianna will probably move this thread to the New Holland area. I did find out that owning the service manual is your best friend because it list the codes plus shows you how to fix it. They usually can be purchased thru NH's website or a your local dealership. A lot of owners here own a manual to their machine and discuss problems here, and in most cases are solved or a method of repair is determined. Take care. -robert
