Yes it does. The 25 tells us that it is an 'improved' Super 55. Tractors prior to that started with specification 15. 550s started with 35, went to 45, 55 and 65 but the second digit was always a 5, denoting a Super 55 or 550. (They did eventually go to a 3 digit prefix before it was over.) The rest tells us what equipment the tractor was equipped with, such as gas or diesel, and what tires. I wish I could tell you what the 0036 coded for, but at this time I don't know.

Your serial number is actually 47-324, and the number 518 is your transmission code. 518 was the code for a regular transmission, 6 forward and 2 reverse. When they came out with the 550s, they made some changes to the transmission, so the code was changed to 519. There are other codes, but you only see them on special tractors like fork lifts and ones with a 4 speed shuttle shift.

On a personal note, your tractor was made only 7 units before mine, as I have serial number 47-331 518. I bet they were made on the same day!
