My husband passed away in January. I have 6 tractors; 4 of them he put a price tag on, 1 of them he told me to keep, this one - a Massey Ferguson Serial Number "TO - 28173" was his next project; does not run but appears to be all there. Has some new parts on it (but I can't tell you what they are). Good tires on back. Car tires on front. No idea what year or model or value; can anyone help to identify this thing and help me to figure out what it might be worth?
