Proper product identification is dependent on obtaining and interpreting the model and serial number. These will be found stamped on top of the transmission housing at the left front corner.

Early agricultural and industrial model numbers (1955 - 1962) consisted of three digits followed in some cases by an alpha or numeric suffix. The first digit designates the engine size and tractor type, the second digit the transmission type and the third digit the year range of the series.

Later tractor model numbers (1962 - 1964) consisted of five digits followed in some cases by an alpha or numeric suffix. The first digit designates engine size: the second digit, successive models; the third and fourth digits, tractor type; and the fifth digit, transmission/PTO/hydraulic type.
