How to read the serial number list:
Tractor serial number lists nearly always show the first tractor built in each year. The other tractors for that year will have successively higher numbers. Your serial number should lie between two of the stated numbers. Example serial number list:
Example: if your serial number is 900, then your tractor was built in 1981.
The list only shows the number from the first tractor built in each year. Unless you happen to have the first first tractor off the production line, then your particular number will not be on the list. Your number will lie between two listed numbers.
