In the autumn of 1989, the revamped 54-series TS/TX/TZ models were introduced. The design of the four-cylinder 103 model resembled the smaller model series, as shown in the first picture. Larger models still featured a black “joint line” on the hood. A new top model for the series was the 155-54, with 145 horsepower. All six-cylinder engines were updated 6.2-liter MWM units. The new front axles had a steering angle of 50 degrees. Electric lift was now standard on the TX and TZ versions. The TZ models still featured cab suspension. Meanwhile, the Tractoradar onboard computer became an optional extra even on the TZ versions.

Initially, the only transmission option was the 16+16 mechanical shuttle gearbox from the previous model series. At the beginning of 1991, a three-stage electro-hydraulic Tractoshift transmission, developed in collaboration with Steyr, became available. This brought the number of gears to 24+8. The reverse speed corresponded to the middle position of the shuttle. Both 30 km/h and 40 km/h versions were still offered. The faster version included a driveshaft brake.

Compared to the previous range’s massive external dimensions, the length was significantly reduced, but the height remained over 3 meters. The fuel tanks were larger than before, and in the cab-suspended model, there was no need to compromise on capacity. The cab noise level was 80 dB, and 78 dB in the suspended version.

The better-equipped version was the Tracfor, similar to the smaller models. In 1991, an even more complete model called the Nectra was introduced, available for the 120-54 and 155-54 models. The Nectra was gold-colored. Standard equipment included air conditioning, leather seat, cab suspension, and ACET – a digital display unit analyzing engine load, driving speed, and fuel consumption.

Another new model for 1991 was the 106-54 TL, which was mainly a budget six-cylinder tractor designed for the German market. It partly utilized the technology of the smaller model line, and its appearance resembled the four-cylinder models. However, a better-equipped Tracfor version of the 106-54 was also available. In 1995, the 106-54 TS was introduced.

In 1994, the Tractonic hydraulic shuttle was introduced as an optional extra. At the same time, new model versions arrived: the TXE was a TX equipped with Tractonic. The Z was a TS-level tractor with cab suspension. The ZC was a suspended TX, and the ZCE was the same equipped with Tractonic. In addition to these ready-made packages, accessories were also available as options.
