In the summer of 1982, Deutz-Fahr discontinued 5-cylinder tractor engines and introduced new 4-cylinder models at the lower end of the DX series: the DX 80 (75 hp), DX 86 (82 hp), and DX 92 (90 hp). The smallest was naturally aspirated, while the two larger ones were equipped with a turbocharger. Unlike previous models, the engines were fitted with a thermostat-controlled turbine clutch, which engaged the cooling fan as needed.

The four-wheel-drive models featured new Sige front axles with a central shaft. In the two smaller models, unlike other DX models, there were drum brakes and push-rod sensing. As for transmissions, the smaller models had 15+5 gears in the 30 km/h versions and 18+6 gears in the 40 km/h versions. The DX 92 had a more robust TW 902 transmission with 18+6 gears. The DX 92 also featured a ceramic clutch plate. The transmissions were fully synchronized, and the gear levers were located on the side. At the time, gear shifting was exceptionally smooth.

The DX 80 and DX 92 models were imported to Finland in 1983. The equipment level was high here: for example, front weights, quick coupling hitches, and a timer-equipped Eberspächer heater were included as standard equipment. The heater, however, was not very reliable.
