The American 7R series was gradually updated – the most recent entirely new model line had been introduced in 2011. The most significant features in the 2020 lineup were a new cab and Stage V engines. The smallest model now had a maximum output of 290 hp, whereas previously the smallest was rated at 249 horsepower. Correspondingly, at the top end, there was 373 hp instead of 352 hp. The engines in the two smallest models were 6.8 liters, while the others were 9.0 liters. The full powershift e23 transmission was now standard in all models. It had 23 forward gears and 11 reverse gears. Each gear was 15% faster than the previous one. The speed of 40 km/h was reached at 1520 rpm. The gear automation covered all gears and adjusted the gear selection according to the most economical RPM range for use. An optional stepless AutoPowr transmission was available.
The cab was larger and quieter than before. As an accessory, the new CommandPRO joystick was available for AutoPowr models. The tractor price included a 5-year JDLink telematics subscription, for example for remote maintenance purposes. A new innovation was the EZ Ballast, a 1.7-ton additional weight attached under the engine, which could be attached or removed in seconds without leaving the cab. Front axle suspension and electrically adjustable mirrors were standard, but for example cab suspension, LED work lights, and recording of engine data were optional extras or included in packages.
