Trying to fix my grandfathers D4-12 for him. This was his grandfathers tractor, my grandfather restored it 20+ years ago and it has been sitting under a tarp and shed ever since. He told me two years ago that the transaxle is bad, I asked him well lets fix it he said we can't we need a new transaxle so my search started then with no luck just out of the blue I found this website joined and got some responses. I am located in north carolina just outside of charlotte. If anyone could give me some information on the tractor and also where I might could find a transaxle it would be greatly appreciated!
