The Cub featured IH's "Cultivision" offset engine and steering. Three major series of the original Cub were built: the Farmall Cub until 1964 (sn 224703), the International Cub until 1975 (sn 248124), and the new International Cub until the end of production in 1979.  The International Cub's PTO ran counter-clockwise ("backwards") and at full engine speed, making it incompatible with standard PTO-driven equipment. In 1975 the "Increased Power" New International Cub was released.
