Hello Guys I have been on the Farmall site for a while now but I traded my Farmall H for a D15 Diesel today it has 4 new tires, new alt. and the pump was just rebuilt. He said it was a 1961 but the ser# is not readable. The side of the block has 1 19 61 on it. Is this a number that can be trusted? This family ownd the tractor for the past 15 years. I will order manuals for it tomorrow any ideas were to find year, or ser# beside the torque tube. Thanks Scott

I just posted on your other post, there were only 2 series of d-15, so in some ways, easy to identify which series, just answer these questions: 1. Is the muffler round or oval, and if it is oval, does the hole in the hood look like it was factory cut as an oval? 2. 6 or 12 volt? 3. the power director clutch handle, is there just a button on top, or is there a lip or thumb guard around the right side and front of the lever, cast into the handle? 4. What is the outside width, as best as you can measure it from outside of the cultivator frame rails? 5. Which type of oil filter does it have, modern screw on type with central, internal pipe thread nipple sticking up or the older screw on type with the metal pipe extending up into the rag stuffed filter, and the external, "mayonnaise jar" threads on the outside edge of the filter?

The engine serial number on a gas is stamped on the left side, to the rear of the carb. Don't know about the diesel. Regarding the number on the torque tube, maybe some paint remover will expose it.
