Fahr developed its last tractor series together with Güldner, and they represented the so-called Europa series. At the lower end of the range were models smaller than previous Fahrs, Güldner-manufactured D 66 and D 88, which corresponded to Güldner's AX and Spessart models. The transmission was ZP’s 6+2. The lowest gear in all the new models was slower than before, and a separate crawler gear was no longer offered. The differential lock was standard, and the power take-off (PTO) was available as an optional extra. The weight transfer system was also standard on all the new models.

The D 130 A was replaced by the D 131, which was available in both air-cooled and water-cooled versions. The model was developed and manufactured by Güldner and corresponded to their Tessin model. The transmission was ZP’s 8+4. The 1000 rpm PTO and the driving PTO were standard.

The largest of the new models was the D 177 (Güldner Toledo). Unlike the others, it had a Daimler Benz high-speed pre-chamber diesel engine originally designed for automotive use, mounted on top of the chassis. The transmission and rear axle were purchased from ZF. The faster version D 177 S was imported into Finland, where the standard equipment included, in addition to the 1000 rpm PTO, a dual clutch.

The successor to the D 180 was the D 133 N in 1959. It corresponded to the Güldner Burgund but was a tractor based on Fahr technology except for the engine and transmission. The engine was only a 1.3-liter 3-cylinder, whose torque lagged far behind its predecessor.

In 1960, the D 131 models were replaced by the D 132 models. These had a longer and lower structure, which had done away with the portal axle.

Especially the D 133 and D 177 sold well, but after Deutz became a shareholder in Fahr, the production of Fahr tractors was discontinued in 1961.
