A power train apparatus and motor grader are described. The apparatus or motor grader includes a power source for providing rotational mechanical power. A first output interface of the power source is driven by the rotational mechanical power from the power source and rotates around a first axis A differential includes at least one output shaft rotating around a second axis offset from and parallel to the first axis. A first gear is included in the differential, the first gear rotating around the second axis and providing rotational mechanical power to the at least one output shaft of the differential. A second gear rotates around the first axis, the second gear receiving rotational mechanical power from the output interface to the power source and providing rotational mechanical power to the first gear.
