The invention relates to a method for propelling an articulated tracked vehicle (1) provided with at least a front and rear vehicle portion (2, 4), comprising a front drive shaft (6), which rotates a front track (8) on the front vehicle portion (2); a rear drive shaft (10), which rotates a rear track (12) on the rear vehicle portion (4), the front drive shaft (6) being disposed in the front vehicle portion (2) and the rear drive shaft (10) being disposed in the rear vehicle portion (4). At least one motor (20, 34, 36) rotates the respective front and rear drive shaft (6, 10) in order thus to propel the vehicle (1) at a speed in relation to a ground surface (16). The front drive shaft (6) is rotated at a first speed and the rear drive shaft (10) is rotated at a second speed, which first and second speeds are different, so that the front and rear tracks (8, 12) rotate at different speeds.
