Challenger MT835B-MT875B

The Challenger 800B series models were introduced in 2005. The appearance was slightly updated, and the tracks were 25 cm longer than before. At the top of the range was the MT875B, which had a maximum power of 600 hp. To protect the transmission, power was reduced at speeds under 6 km/h in this model. The power of the other models remained roughly the same. The difference between maximum power and nominal power was even smaller, meaning that almost the maximum power was available over a wider range than before. Engine capacities had increased to 14.6 liters in the three smaller models and 18.1 liters in the two largest ones. The 16+4 powershift transmission remained unchanged. Hydraulic output was 166 liters per minute, but in Europe, the 223 liters per minute version was mostly sold.

With the standard 699 mm rubber track chains, the width remained just under three meters. There were more track options than before for different purposes. The cabin noise had dropped to 73 decibels.

At the same time, in the Challenger wheeled tractor lineup, the MT400B series corresponded to the MF 5400 series, the MT500B to the 6400/7400 series, and the MT600B to the 8400 series.
