I recently bought a Ford TLB that was listed as a 641. After I got it home and started looking investigating the markings, I suspect it is not. I found stamped on the transmission (behind the starter) the following numbers: 40306 74196. I have read that the model number for the 600 series is supposed to be ABOVE the serial number. In this case these two numbers are in line with each other. I checked the engine mark on the lower right hand side and it reads EAF-6015-J. Decoding the model/serial number and the engine mark leads me to believe it is a 1000 series tractor, but it has the egg crate style grill of the 800-900 series and other things do not match up. It has a Select-O-Speed transmission, adjustable front end, and since it has a loader and a backhoe on it, it has PTO outputs on both front and back. I would appreciate any help on identifying this tractor. Thanks G
