I am new to the form and am looking for information. My Grand-dad bought a new 4000 Ford tractor serial number 2154. From what I have found it was made 1962 however they are all called 63 or 64 models. The sheet metal is in good shape and I am thinking of have it restored and driving it in parades or small local shows. My question is I guess is it worth it? Any discussion on this model? I know I will need new rear rims and some other items. It is still a 6 volt system should I change it to a 12 volt system? I also was told that it was possible to put on a 9 volt battery on a 6 volt system to give it more power. Could this be true?
