The Case IH Farmall A models corresponding to the New Holland TD5 series were introduced in the fall of 2012. These models, with 65-113 horsepower, had very little in common with the 45-55 horsepower Farmall A models introduced the previous year. The two smallest models were equipped with 2.9-liter engines from the 8000 series. The three largest models had 4.5-liter NEF engines featuring mechanical engine control and a viscous fan. Compared to the preceding JX series, the top end of the lineup included two more powerful models with 38-inch wheels.

Unlike the New Holland models, the transmission in the smaller models was also a 12+12 speed transmission equipped with a reverser. In the four-cylinder models, the reverser was hydraulic. The power take-off (PTO) as standard included 540 and 750 rpm speeds as well as a ground-driven PTO. In Finland, the standard equipment included a front axle limited-slip differential and three hydraulic valves. The four-wheel drive and PTO clutches were mechanical. The lift system was also always mechanical. The placement of controls in the cab had been improved. There was a window in the roof. Noise level was reported as 86 dB in Germany, but no noise level was specified for Finland.
