Methods and systems for a hydromechanical transmission are provided herein. In one example, the transmission system includes a hydraulic pump and a hydraulic motor rotationally coupled in parallel with a first planetary gear set and a second planetary gear set. In the system, sun gears of the planetary gear sets are rotationally coupled to the hydraulic motor, a carrier of the first planetary gear set is rotationally coupled to a first clutch and a second clutch, and a ring gear of the second planetary gear set is rotationally coupled to a third clutch.
