Abstract

A powershift transmission for an agricultural machine includes a transmission housing, an input shaft and an output shaft unit. The input shaft and the output shaft unit extend at least at a distance within the transmission housing. The transmission also includes an auxiliary shaft arranged within the transmission housing and offset between the input shaft and the output shaft unit. The input shaft and the auxiliary shaft are connected to one another via a front-mounted range unit, and the auxiliary shaft and the output shaft unit are connected to one another via a rear-mounted range unit. Each range unit includes at least two individual gear wheel pairs which are coupled or decoupled. The output shaft unit includes a main output shaft and an auxiliary output shaft coupled to one another via a reduction gear unit.
