The Xerion 12, developed since 2017, was introduced in the autumn of 2023. It was available either with wheels or equipped with four tracks (Terra Trac) and was the most powerful tractor on the market with a stepless transmission. The engine was Mercedes’ 15.6-liter unit with a maximum output of 585 or 653 hp. The oil change interval was 1,000 hours. The transmission was ZF’s stepless four-range Eccom 5.5, which had been introduced in the 5000 model already at the beginning of 2023. However, the 12-series featured a drive train with a gear ratio that rotated the transmission 15% faster than the engine, limiting drivetrain load. A speed of 40 km/h was reached at 1,400 rpm. The wheeled version also offered a top speed of 50 km/h. The axles were manufactured by the Hungarian company Raba. The weight was evenly distributed between the front and rear axles. The hydraulic system could deliver up to 537 liters per minute at its most powerful. The power take-off (PTO) and the lift were optional extras. With the lift installed, the steering angle was limited, and despite four-wheel steering, the turning radius was 18 meters.

The cab was almost the same as in the Lexion combines, accessed via seven steps. The cab was not rotatable. The control system featured a 12-inch CEBIS touchscreen, and for automatic steering, there was an additional CEMIS 1200 display. The cab had mechanical four-point suspension, automatic air conditioning, and 20 LED work lights as standard. In external dimensions, there was not much difference compared to smaller Xerions, except for a 44 cm greater width, but the tracked version weighed a substantial 25 tons. With tracks measuring 914 mm, the width was 329 cm. The total capacity of the two fuel tanks was 1,400 liters. By changing the direction of the fan, it was possible to clean the coolers of the engine, transmission, hydraulics, and axles.

The Xerion 12 was chosen as Tractor of the Year 2024.
