In 1947, IH introduced the Farmall Cub below the Farmall A, which was aimed at the smallest farms. Its design was very similar to the Farmall A: the driver sat on the right side of the centerline, and at the rear there was portal axle suspension to increase ground clearance. The 1.0-liter gasoline engine produced 10 hp. There were three gears, and the top speed was only 10 km/h. Steering brakes were standard. The Cub's PTO rotated in the opposite direction and at the same speed as the engine. The Cub was initially well received: in its first year, 45,000 units were sold.

In 1948, hydraulics became an optional accessory. In 1954, the grille with vertical bars was replaced by one in the style of the 100-series models, and in 1956 the grille and wheel rims were painted light-colored. In 1959, a new grille was introduced again, following the 60-series design. The main user base was more oriented toward property maintenance than farms, and considering this, the low-clearance Cub Lo-Boy was introduced in 1955. Serving the same purpose was the color change to yellow in 1960. In 1964, a new angular white-and-yellow Cub was introduced, now bearing the International brand. Not many tractor models have lasted 32 years with so few changes. In total, about 250,000 Cubs were produced.
