I purchased this tractor from a friend of a friend last weekend and have been researching it ever since. The seller was adamant that it was a 1961 Ford 600 series 640/641 model. He had what he stated was the original owners manual that came with the tractor. It was for a Ford NAA. The tractor is in fair condition. It starts easily and runs well with a little smoke on the #1,2 and 3 cylinders, but has a bad piston or rings in the #4 cylinder. The rest of the tractor is mechanicly sound and the body is in fair to good condition with very little rust and very few dents. I have found the seriel number on it, by using the Vintage Ford Tractor web sites instructions. It is; NAA75408 with a diamond suffix. This traces back to a '53/'54 NAA.Here's my problem. I used the Vintage Ford Tractor web site that compares the NAA to the 600 series and there are two discrepancies. 1) The grill cover that the web page designated to the 600 series in on this tractor. (with the oblong shaped hole) 2) The left side combination foot rest/tool box is not on this tractor. The only other descriptional difference I can tell also is that the seller was adamant that the grill emblem was that of a 600 series. (it is missing now) So.... Do I base my research and restoration on the seriel number for the NAA. Or do I go by the 600 series characteristics on the body of the tractor and the sellers word. As a foot note, I've looked over the mounting nuts and bolts of the body and their integrity appears not to have be broken. They appear to be the orignal nuts and bolts. Unless they have been painted over. Any comments ould be appreciated.
