For the year 2014, John Deere introduced the updated 8R series tractors, which had to adopt the SCR technology that Deere had previously rejected. There were two turbochargers arranged in series. The model range was broader than before, and even the smallest model, the 8245R, was now brought to Europe. The hydraulic flow rate was now standard at 227 liters per minute, and with two pumps, 321 liters per minute. The control armrest, CommandArm, was completely redesigned. The cab noise level dropped to 69 decibels, among other things thanks to laminated windows. The transmission options initially remained the previously used 16+5-speed powershift and the stepless AutoPowr. In 2015, the high-efficiency e23 PowrShift transmission was introduced, featuring 23+12 speeds. A speed of 50 km/h was achieved at 1,670 rpm. With the new transmission, the 16+5 version was removed from the largest models.

The rubber track models were known as the 8RT. They featured suspension, which allowed for a speed of 42 km/h. The rubber track version was available in models 8320-8370.

In the autumn of 2016, a new top model, the 8400R, was introduced, with a maximum power of 450 hp. Its only transmission option was the mechanical e23. The 8400R had a heavier-duty rear axle and wheels compared to the rest of the range. In mid-2017, the 8R series received the 4th generation CommandCentre display, which allowed multiple windows to be opened and moved around.
