I'm trying to get an old Ford 4000 diesel back running that belonged to my father n law, he passed 2 months ago. I can't read the serial #, looks like it might have been repainted over. If I removed the paint would the # be visible? By the looks of the tractor I guessing it's a 62-64 model, blue motor and frame with white fenders and hood. I tried cranking it the otherday it will turn over but won't start, not sure how long it has sat. It has a key on the left and a push button right above it. Does the start switch on top of the trans have to be pushed in along with the button above the key to get it to start? Not familiar with the old Fords but have always loved them so trying to learn.
