A drive system for a work vehicle is provided having a differential gearbox with an output pinion coupled to a bull gear where the bull gear is coupled to an axle and the axle rotates about an axis below that of the bull pinion's rotational axis. The axle is engaged to a drive gear which is in turn coupled to a track. The differential may have two such axles coupled to two suspensions, and may be a part of an articulated vehicle. The vehicle may have two such differentials and suspension arrangements, one in a front frame of the articulated vehicle and one in a rear frame.
