high efficiency work vehicle traction systems containing drive assemblies are provided. In one embodiment, the working vehicle traction system includes a motor, a variator assembly, and an auxiliary power take-off (PTO) shaft, which is coupled to the motor and rotatable about a power path geometry axis. primary when driven by the motor. The drive assembly in turn includes a drive motor and a drive gearbox. The variator gearbox contains a planetary gear system, which is coupled to the variator motor and the pto auxiliary shaft. the planetary gear system is rotatable about a planetary geometry axis substantially parallel to and displaced from the primary energy path geometry axis.
