For the year 2015, the model numbering of TC models manufactured in Poland was revamped. At the same time, the 4-cylinder model received a new cab, rounded shapes, and a larger grain tank, features that had already been introduced to the larger models the previous year. All engines now featured SCR technology.

The cab, named Harvest Suite, had the same chassis as the CX. The controls were positioned on the armrest, and the cab noise level had dropped to 74 decibels. The displays were located on the A-pillar, and there was no separate driver computer display like on the CX. The RS models had a straw chopper; as a new feature, it was now also available for the smallest model. The electric hydraulic header lift and stubble height control were now standard. Basic headers featured an electrically driven auger, while the wider ones had hydraulic operation. Optional extras included a Varifeed header with adjustable length, electric sieve adjustment, and a grain spreader. In Finland, the TC5.80 came standard with an air-suspended seat and a differential lock.

For the year 2019, the TC4.90 – TC5.70 engines were changed to 4-cylinder versions. Stage V versions arrived in 2021. With the 8300-liter tank, the unloading rate was 100 liters per second instead of 60 liters per second for the smaller tanks.
