Beschreibung
Zusammenfassung:	A steerable crawler track for an agricultural utility vehicle such as, a tractor or a self-propelled harvesting machine has a left-side track roller unit, a right-side track roller unit, a differential having a transmission input driven by an engine, a first transmission output for driving the left track roller unit, and a second transmission output for driving the right track roller unit and a hydraulic transmission having a variable transmission ratio (i). The transmission outputs of the differential are coupled to one another via the hydraulic transmission such that the ratio of the rotational speeds (nl, nr) of the transmission outputs are influenced by changing the transmission ratio (i) of the hydraulic transmission.
