It's a 1965-1968 Ford 2000 or 3000 with a diesel engine. They were basically the same tractor but the 3000 was rated at slightly higher horsepower due to a higher maximum rpm allowed by the governor. The headlights in the grill indicates that it was probably made in one of the 2 European factories, so the serial number will probably start with a B (for the Basildon England plant) or an A (for the Antwerp Belgium plant). The US made models started with a C and had the headlights sticking out to the sides of the upper grill. The model number, serial number and production code should be stamped into a flat spot on the transmission bell housing just toward the rear of the tractor from the starter. If you're lucky, the foil sticker on the under side of the right side of the hood that has the same numbers will also still be there. Check out This Link to see a picture of where the numbers are stamped in the bell housing and for the information on how to decode the numbers.
It's hard to see, but the smaller number under the C7NN6015 casting code looks to be 8B20, and if that's the case, then that particular sub-assembly (engine) was assembled on February 20, 1968, and the tractor itself was probably assembled a few months later.
You would have gotten a better response from the "Big tractor by brand" Ford section of the forum instead of the CUT section.
