My 650J deere dozer stopped moving today. The left side stopped and then the right side slowly stopped also. A service book picture on the monitor came on and a code on the TCU is F 3A6. Does anyone know what this means and how to fix it? MB
if you call your local JD dealer theyll tell you what the code means, i had one where the transmission control unit, the black box by your left arm had a corroded connection and i had to replace it and clean up the others then it worked, and on a different JD dozer i had a speed sensor below the operators seat go bad. but the dealer will tell you what the code means and thatll give you a better idea of where to look, if you need info from the repair manual i have one for that machine
