Introduced in late 1931, the Caterpillar Fifty (5A) was first released with the "FIFTY" nomenclature cast on the sides of the radiator housing and had the fuel tank in front of the operator. By 1933 the designation was moved to the front of the radiator, and the fuel tank was moved to behind the operator's seat.
