ABSTRACT:
A transmission for use with a power source and a load includes a primary sun gear adapted to be coupled to the power source, a hydrostatic power unit including a pump coupled to a motor, a ring gear driven by the motor, a secondary sun gear coupled to a first output shaft, a compound planetary gear carrier coupled to a second output shaft and a compound planetary gear carried by the compound planetary gear carrier and in engagement with the ring gear and the secondary sun gear. The first output shaft and the second output shaft are adapted to be selectively coupled to the load.
