Claim 11:
12. A hydromechanical variable transmission, comprising: a hydrostatic assembly including a variable displacement hydraulic pump and a variable displacement hydraulic motor; wherein the variable displacement hydraulic pump is mechanically coupled to a first clutch via a first gear that is positioned coaxial to an input shaft; a carrier included in planetary gearset mechanically coupled to an output shaft; a third clutch positioned coaxial to the first clutch, wherein the first clutch is a forward drive clutch and the third clutch is a reverse clutch; and a fourth clutch positioned coaxial to a second shaft and selectively mechanically coupling the input shaft to the second shaft via a second gear; wherein the input shaft is mechanically coupled to a prime mover; wherein the input shaft includes the first clutch positioned coaxial thereto and configured to selectively mechanically couple the variable displacement hydraulic pump to [a] the second shaft; wherein the output shaft is designed to couple to an axle; and wherein the output shaft is selectively coupled to the variable displacement hydraulic motor via a second clutch that is positioned coaxial to the output shaft.
