Massey Ferguson tractor serial numbers usually have 9 numbers and one letter. The first three numbers are the manufacturing code, the following 4 digits are the model code and the last 2 digits are the year of production. The letter is an indication of the manufacturer’s assembly plant, with each plant being designated by a specific letter. For example, a Massey Ferguson GC1715 produced in 2019 would have a serial number beginning with 825, indicating it was manufactured at the Massey Ferguson factory, followed by the model code 1715 and ending in 19, indicating 2019.
