Abstract: A new tracked vehicle arrangement with a main vehicle and a trailer, where each of the main vehicle and the trailer have a track assembly on either side, and the tracks of the trailer are driven by the prime mover of the main vehicle. In the longitudinal direction of the main vehicle, only a small fraction (less than 25%) of the length of the main vehicle's cab, which is mounted above the frame, overlies the main vehicle's track assemblies, whereas the fuel tank is located between the cab and the prime mover. In a widthwise direction of the tracked vehicle, the fuel tank at least partly overlies the right and left track assemblies. This provides a counterbalance for the trailer, which has a platform attached by a first pivotable connection to the frame of the main vehicle and by a second pivotable connection to the frame of the trailer.
