Welcome aboard Bigchief. Most people on here are going to ask what year is the 4000? Easy to tell. Is it a 4 or 3 cylinder? There is a sub-form on here that is specific to Ford/New Holland tractors. You may want to post it there.
Also there is another site Antique Tractors - Yesterday's Tractors : Antique Tractor Headquarters that may help as well.
And last but not least. In computer lingo, ALL CAPS is the same as yelling at someone. Better to type in lower case then all caps.
