A multi-stage planetary gearbox, in particular a torque split gearbox of a work machine, having a housing which accommodates four planetary gearsets, a plurality of shafts, and shift elements including brakes and clutches which implement different gear ratios between the drive and output shafts. The drive shaft couples a carrier of the third gearset which can couple, via a first clutch, a third shaft that is coupled to a ring gear of a second gearset and which can be connected, via a second clutch, to a fourth shaft connected to a sun gear of the third gearset. A fifth shaft couples a sun gear of the second gearset and can be locked, via a first brake, with the housing. A sixth shaft couples a ring gear of the third gearset and a carrier of the second gearset. The output shaft is coupled to a carrier of a fourth gearset.
