I have a john deere 8420tractor that will not go into gear and the fault code is pcu 44. I have swapped relays k 17 k18 k22 and still no results. Any help is appreciated
I have a list fault codes from both an 8320, and 8530, but cannot put my hand on them at the moment. We had a very good relationship with the local Deere dealer, so most of time we called in for fault codes. I will try and do some digging.
