Abstract: The present invention relates to a hydromechanical transmission which provides as infinitely variable speed ratio in two different stepdown transmission ranges. The transmission comprises a displacement pump having a first rotator connected to an input shaft and a second rotator connected to an output shaft for transmitting a portion of the torque supplied from the input shaft as the reaction torque and for generating high pressure oil, a variable displacement motor which is driven normally or reversely for changing the energy of the high pressure oil to the driving torque, a first transmission gear having a first clutch means for selectively transmitting the torque regenerated by the motor being driven in the normal direction, and a second transmission gear having a reverse mechanism and a second clutch means for transmitting selectively the torque regenerated by the motor when driven in the reverse direction.
