Info

The JD 8020 series comprised five models with power outputs ranging from 200 to 295 hp. All of them were equipped with an 8.1 liter common-rail engine. In addition to the rated power, they could deliver another 20–30 hp at lower engine speeds, and peak torque was up by 40 percent. The transmission remained a 16 + 5-speed full-powershift unit, now supplemented by shift-automation that worked the same way as the quick-shift system on the smaller model ranges.

Optional equipment included computer-controlled hydraulic suspension on both the front and rear axles, and an active air-suspension seat was also available. As standard, the tractors featured headland management, and—unlike on the smaller series—you could program gear changes into the system. The hydraulic valves were electrically controlled, with four valve blocks fitted as standard. Both hydraulic performance and overall dimensions increased noticeably, while the weights stayed under control. Alongside the standard models, there were also T-marked versions fitted with rubber tracks.
