An auxiliary drive assembly includes a mounting structure configured to mount a first hydraulic drive component in a fixed position with respect to a second hydraulic drive component along a drive axis. A first shaft coupled to the first hydraulic drive component is configured to rotate with respect to the drive axis. A second shaft coupled to the second hydraulic drive component is configured to rotate with respect to the drive axis. A power takeoff device is arranged along the drive axis between the first and second hydraulic drive components and coupled to the first and second shafts for co-rotation with respect to the drive axis. The power takeoff device is configured to transfer rotational power from the power source as received from the first hydraulic drive component to an auxiliary component of the work vehicle.
