At the larger end of the Axial-Flow lineup, the move was made to the 250 models for the year 2019. The changes in technical specifications were minimal. More emphasis was placed, as with other large combines, on threshing automation, which was, however, an optional feature. The lifting cylinders of the cutting platform were larger than before, and the cutting platform’s tilt angle could be adjusted hydraulically while driving. The new transmission included only a field mode and a road mode.

Axial-Flow was based on a single longitudinal drum with a diameter of 76.2 cm, which handled both threshing and separation. Different rasp bars under the threshing section were switched according to the crop being harvested (grain, peas, corn). Likewise, there were interchangeable elements for the separation area. The grain flow speed inside the drum was adjusted using concave sheets, which for the first time were available as electronically adjustable instead of screw-adjusted. The sieves were similar to those of a conventional combine. The chopper was positioned inside the straw hood so that the straw fell directly from the drum onto the chopper. The standard grain tank unload rate was a moderate 113 liters per second, but there was an option for unloading at 159 liters per second. The cab was still available in Comfort and Luxury versions.

The AFS Command automation controlled adjustments such as fan speed, sieve settings, rotor speed, rotor concaves, and driving speed. The sieves featured sensors to detect the pressure of the air produced by the fan. The fan was also adjusted according to uphill and downhill driving. Machine vision was used to monitor the amount of broken grains. There were four different threshing strategies. It was possible to aim for the best possible grain quality and minimal losses by keeping the driving speed sufficiently low. Performance mode aimed for the most efficient use of the machine while keeping threshing losses below a selected threshold. The third option was to keep the amount of grain coming into the machine consistent by adjusting the driving speed. When rain was threatening, it was possible to switch to the highest possible threshing capacity and let the automation try to minimize threshing losses as much as possible.
