I I am new here and thanks for letting me join. I have a 2005 John Deere 700JLGP dozer. I replaced a track speed sensor so started the calibration.it gave me three fault codes and now my dozer won't move everything seems to be working correctly except when I push my pedal it doesn't idle down. Put in gear it won't move
Welcome to HEF Ray ! Let's start with a complete machine serial number. Please list all the active you codes that you have (list by the number, not the description please). Why was the speed sensor replaced?
