I have always wanted to restore a tractor. Well a friend of mine has a JD model 70 diesel mid 50s vintage that doesn't run cus the head has been off for years. He thinks he has all the parts but not sure. Now for the good news, he said I can have it for free. Just haul it off. Now my question is, what am I in for on this restore? Will it be a money pit and working full time how many years will this take? I may sit for another year before I can start on it. Thanks in advance.
