Abstract: The invention relates to a working machine comprising a working machine frame, at least one propulsion axle having an elongated main body comprising a first end portion, a second end portion and a center portion arranged between the first and second end portions. The elongated main body has a main body length (MBL) extending from the first end portion to the second end portion. The working machine further comprises a propulsion axle suspension arrangement arranged between the working machine frame and the propulsion axle, the propulsion axle suspension arrangement comprising a first suspension device and a second suspension device arranged on opposite sides of a center of the elongated main body. The first and second suspension devices are arranged in the center portion of the elongated main body.
