Abstract: An agricultural working machine has a first axle and a second axle, multiple ground-engaging means disposed at the first and second axles that are at least partially drivable by a drive engine or are steerable using steering-knuckle steering, a steering-angle sensor disposed at a steerable ground-engaging means for detecting a set steering angle (?th) and a steering brake for the selective braking of one or more drivable, ground-engaging means for steering support. A control unit controls and regulates the at least one steering brake based on a steering angle (?th, ?tat) or a slip angle (?) of at least one of the steerable ground-engaging means.

Abstract: An agricultural vehicle having a full-track design with a vehicle structure on each side of which, relative to a vehicle longitudinal axis, a track roller unit is arranged. The track roller unit has roller unit body to which a front deflector roll, a rear deflector roller and a plurality of yoke-type track rollers arranged therebetween are coupled, and an endlessly closed track belt that wraps around the rollers/roller. All the rollers are suspended with respect to the roller unit body in that assigned to a roller or a group of rollers in each case is a spring element, which is acted upon by fluid, for the suspension thereof with respect to the roller unit body.

Abstract: 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.
