A drive assembly for a work vehicle includes a housing arrangement, a drive shaft rotatable in first and second clock directions, and a two-stage planetary gear set coupled to the drive shaft. The gear set includes, or is coupled to, an output element. First and second clutch arrangements are configured to selectively engage the gear set to effect first and second gear ratios, respectively. A step ratio from the first gear ratio and the second gear ratio is 3:1. At least one first actuator and at least one second actuator are configured to effect movement of the first and second clutch arrangements, respectively, to selectively engage the gear set. The drive shaft and the output element rotate in a same clock direction with the first clutch arrangement engaged with the gear set, and in opposite clock directions with the second clutch arrangement engaged with the gear set.
