Info

In the Challenger MT700C series introduced in 2008, the appearance and the cab were updated. In the familiar 8.8-liter Tier III Caterpillars, the maximum power was about twenty horsepower more than before. The gearbox was still a 16+4-speed electronically controlled full powershift. The improved cab featured a new 7-inch TMC-ISOBUS display, which was the same as in MF tractors. The rounded-line instrument panel was also similar to that of MF. The programming of the headland automation was simplified. In the hydraulics, there was a new LIFD system. In situations where the flow demand exceeded the pump output, the system limited the output of each of the (up to) six valves by the same percentage.

The data has been collected primarily from brochures. In some cases, sources contain conflicting information. In such cases, we have attempted to select the most reliable information. There is particularly significant variation in speed data, which varies depending on factors such as tire size. For tires, only the size most commonly used in Finland is listed. Other changes during the model history have been addressed in the text section. For the front axle lock, the Finnish term "hammaslukko" (gear lock) is used for all 100% locks.
