Architecture for multiple power source work vehicle powertrain

A powertrain for a work vehicle, comprising:

• an engine having an output shaft;
• and
• a transmission, comprising:
• a continuously variable power source (CVP) having an output shaft mounting an output gear;
• a variator that is operably connected to the engine and the CVP, wherein the variator comprises a first planetary gear set and a second planetary gear set;
• a range shaft having a range shaft output gear mounted thereto;
• a clutch shaft;
• a forward clutch having an input component mounted to the output shaft of the engine and having an output component configured to directly transfer power from the engine to the variator when the input component of the forward clutch is coupled with the output component of the forward clutch;
• a reverse clutch having an input component driven by the output shaft of the engine and having an output component mounted to the clutch shaft;
• a first mode selector clutch having a first input component enmeshed with an output gear of the first planetary gear set and a first output component mounted to the range shaft;
• a second mode selector clutch having a second input component enmeshed with an output gear of the second planetary gear set and a second output component mounted to the range shaft;
• a third mode selector clutch having a third input component enmeshed with both the output gear of the CVP and an input gear of the first planetary gear set and having a third output component mounted to the clutch shaft;
• and
• an output shaft having an output shaft gear driven by the range shaft output gear;
• wherein the first mode selector clutch and the second mode selector clutch are selectively operable to couple the first input component with the first output component or the second input component with the second output component and thereby transfer power from the variator to the output shaft.
