The first models introduced in the 6R series were the large models that replaced the earlier 7030-series tractors manufactured in Germany. These models had a wheelbase of 280 cm. Compared to the 7030 series, they weighed about 600 kg more, and the overall dimensions were larger. The construction was still based on a full-length steel frame. The lineup also still included a model equipped with an electric generator, the 6210RE, which had outlets providing 230 and 400 volts of power for electrically powered tools or for controlling electrically powered work equipment. The engines were 6.7 liters in size and, unlike competitors, did not require urea; instead, they utilized an oxidation catalyst and particulate filter.

The transmission options offered were 20+20-speed PowrQuad Plus and AutoQuad Plus, the stepless AutoPowr, and a completely new DirectDrive dual-clutch transmission with an 8-speed quick shift, which promised to combine the best features of mechanical and stepless transmissions. The hydraulic system provided a flow rate of 114 liters per minute, or optionally 155 liters per minute for an additional cost. The cab was entirely new with four pillars. The noise level was reported as 72 dB, slightly higher than before. The cab’s display screen was larger than earlier models.

In the autumn of 2014, the engines were upgraded to Stage 4 compliant models, and the model numbers increased by 5 steps. A few extra horsepower was also added. Injection pressure was raised to as much as 2500 bar. In addition to the previous emission technology, a light urea injection system was introduced. With the stepless transmission, 50 km/h was now reached at 1630 rpm. The control armrest was updated to be the same as in the 7R models.

In the autumn of 2016, the top models of the range, the 6230R and 6250R, were introduced. These models were more robust than the others in almost every aspect. These models were always equipped with the stepless AutoPowr transmission and the new CommandPro multifunction joystick, which had 11 programmable buttons and allowed acceleration, deceleration, direction change, and cruise control activation by twisting the joystick. The much-desired joystick became available on all 6R models in 2020.
