A hydro-mechanical transmission wherein the mechanical power path comprises three planet gears rotating at different speeds (for any given speed of the associated sun gear). The hydrostatic power path includes a different sun gear, three other planet gears, and a ring gear. Clutch mechanisms are arranged to selectively connect different ones of the mechanically-driven planet gears to associated ones of the hydrostatically-driven planet gears. The percentage of power through the hydrostatic and mechanical power paths varies according to the rotational speed of the output member (ring gear). The transmission occupies a relatively small space, while providing a multiplicity of different hydrostatic-mechanical power hook-ups.
