1. A dual clutch power shift transmission for an agricultural vehicle, comprising:
an input shaft configured to be connected to a prime mover of the agricultural vehicle;
a main shaft rotationally coupled to the input shaft;
an output shaft configured to be selectively coupled to the input shaft to translate power to a tractive assembly of the agricultural vehicle;
an odd shaft and an even shaft, each configured to carry a plurality of gears, each of the plurality of gears defining a predetermined gear ratio between the input shaft and the output shaft;
the odd shaft configured to be selectively coupled to the input shaft via an odd clutch and a master clutch, and the even shaft configured to be selectively coupled to the input shaft via an even clutch and the master clutch;
a forward clutch and a reverse clutch interposed between the master clutch and the odd clutch, and interposed between the master clutch and the even clutch, the forward and reverse clutch configured to be alternatively coupled to the input shaft;
an intermediate shaft assembly interposed between the odd shaft and the even shaft, the intermediate shaft assembly configured to rotationally couple each gear of the plurality of gears with a corresponding gear of the plurality of gears;
an auxiliary shaft interposed between the odd shaft and the output shaft, the auxiliary shaft configured to carry a plurality of range gears, each of the plurality of range gears defining a predetermine gear ratio between the input shaft and the output shaft.
