An agricultural machine transmission has a powershiftable main group arranged upstream or downstream of a powershiftable split group in the direction of force transfer. The split group has an input shaft, an output shaft, and powershift elements, which when selectively actuated permit configurations of at least six different forward gears and at least three different reverse gears between the input shaft and the output shaft of the split group. A driveshaft of the main group is connectable by a first powershift clutch to a first input shaft and is connectable by a second powershift clutch to a second input shaft of the main group. Spur gear stages of the main group can be integrated into the force transfer path by actuating an associated shift element, coupling an associated input shaft to the drive shaft of the main group by configuring a respective gear of the main group.
