History of the Deutz DX
A successor to the six-cylinder D-06
The DX range was presented in 1978 as the successor to the six-cylinder models of the D-06 series. From 1980 four-cylinder models followed, and in the same year the range was extended downwards by the D-07 series with two-, three- and four-cylinder models. The DX was the first tractor range from Deutz-Fahr to be sold with the Deutz-Fahr lettering; the previous range carried only the Deutz name, because Deutz had taken over the Fahr company in 1975. The tractors were painted in Deutz green 74, a colour already used on the D-06 from 1974.
New bodywork and the Mastercab
The appearance was thoroughly revised compared with the 06 series. The DX had a new trapezoidal bonnet, on some models with the exhaust pipe running along the side, and a matching cab of the Mastercab type. The cab was inspired by the cab of the Deutz INTRAC and gave a good all-round view. Only air-cooled diesel engines from Deutz were used, some of them turbocharged.
The models of 1978 and 1980
In 1978 the models DX 85, DX 90, DX 110, DX 140, DX 160 and DX 230 were presented. In addition there were the plantation tractors DX 36 V, DX 50 V and DX 55 V, which were developed together with Agrifull. In 1980 the range was joined by the DX 80, DX 86, DX 92, DX 120, DX 145 and DX 250. Many models of this first DX range had the new TW 90 gearbox, while models from 200 hp used gearboxes from ZF Friedrichshafen.
The revised range of 1984 and afterwards
In 1984 all previous DX models were replaced by a new, revised DX range whose numbering consisted of one digit, usually the number of cylinders, and a two-digit number after a point. After Deutz took over the agricultural machinery business of Allis-Chalmers, the DX models were also sold in the United States under the Deutz-Allis brand. The successor ranges AgroStar, AgroPrima and AgroXtra used largely the same components as the DX.
