The design of the MT800C series introduced in 2008 had been rounded off both on the exterior and inside the cab. The cab also featured a new 7″ ISOBUS-compatible TMC display. The yellow paint was paler than before. The smallest model was dropped from the European lineup, and especially at the lower end of the range the power and torque figures were higher than previously. Emissions complied with Tier III. The transmission was still a Caterpillar-built full powershift with 16 forward and 4 reverse gears. The “one-touch” headland automation could store 35 functions for up to six different implements. You could also program different hydraulic flow rates for work speed and headland speed via the electronic control blocks. The track chains and their carriers were available in polyurethane, which was said to be more durable than either steel or rubber.
With a starting price of around €400,000, the MT800C was somewhat more expensive in Europe than competing American tracked tractors.
The Challenger MT400 and MT500 series made by MF continued as the B-range models, while the MT600C was revamped to match the MF 8600 series.
