Abstract

A powershift transmission for an agricultural machine includes a transmission housing, an input shaft unit and an output shaft, wherein the input shaft unit and the output shaft extend at least in sections within the transmission housing. An auxiliary shaft is arranged parallel to but offset between the input shaft unit and the output shaft. The input shaft unit and the auxiliary shaft are connected to one another via a front-mounted range unit, and the auxiliary shaft and the output shaft are connected to one another via a rear-mounted range unit. The front-mounted and rear mounted range units each includes at least two gear wheel pairs, the at least two gear wheel pairs being individually coupled or decoupled. The auxiliary shaft unit includes a first auxiliary shaft and a second auxiliary shaft, where the first and second auxiliary shafts are coupled to one another via a reduction gear unit.
