A small engine transmission having a hydromechanical transmission unit providing a first power path, and a mechanical power transmission unit providing a second power path. The mechanical power transmission is a planetary gear system having a planetary carrier. The hydromechanical transmission is associated with the mechanical transmission to decrease average hydraulic power flow of the engine transmission to thereby increase operating efficiency and to permit the reduction of an output speed range to reduce transmitted power for the use of multiple modes to achieve a full torque and speed range of the transmission.
