In the fall of 2014, the John Deere 9R series tractors were updated with Stage 4 compliant engines equipped with urea injection. The smaller models still had John Deere's 13.5-liter engines, but the two largest had switched to a 15.0-liter Cummins engine. Power had increased by 10 horsepower compared to the previous models. In the USA, the lineup also included a smaller 9370R. The transmission was now standard with an 18+6-speed PowerShift, and the road speed had increased to 42.7 km/h. Hydraulic output had increased significantly, and with an additional pump, the figure was 435 liters per minute. The cab was updated to Command View III. GreenStar precision farming equipment was standard. The wheelbase, length, and height were considerably larger than before. Likewise, the weight had increased to at least around 20 tons.

There were three tracked versions: 9470RT, 9520RT, and 9570RT. The track system featured air suspension. In the fall of 2015, John Deere introduced its first-ever four-track models alongside these: the 9470RX through 9620RX. Both tracked versions came standard with 760 mm rubber tracks, with the 915 mm tracks available as an option.
