The largest models of the MF 6400 series introduced in the summer of 2003 were the 6485, 6490, and 6495. These were equipped with 6.6-liter SisuDiesel engines and a transmission derived from the 8200 series. The gearbox was a 32+32-speed Dynashift Eco. The hydraulics in these models were load-sensing with a 110 l/min pump. In some countries, an open system with a 100 l/min pump was also available. The lift capacity was 9,100 kg. Optional equipment included, among other things, cabin and front axle suspension. The cabin noise level was 71 dB.

At the beginning of 2004, the flagship of the range was introduced: the 215-horsepower 6499, featuring a 7.4-liter SisuDiesel engine. A few months later, the lineup was complemented by the 6.6-liter 6497 (185 hp), whose engine was the same as the one in the 6495, but otherwise the tractor corresponded to the 6499.

At the SIMA show in spring 2005, the updated 6497 and 6499 were presented. The transmission was now a Dyna-6 with a 6-speed powershift, also available in a 50 km/h version. The rear end was completely new and lighter than before. Likewise, the front axle and front frame structure were new. The engines were 7.4-liter 24-valve common rail SisuDiesels, and the power of the 6497 increased significantly compared to before. These models also introduced for the first time a new design of the engine hood. The 6485–6495 continued unchanged for another year.
