A farm implement includes an undercarriage including at least a front crossbeam and a rear crossbeam and first and second dual track propulsion systems. Each dual track propulsion system includes a first track assembly and a second track assembly. Each track assembly includes at least a track frame, at least two wheels and a track belt looped around the wheels. Each track assembly also includes a track support beam coupled to the track frames of the first and second track assemblies. The track support beam is pivotably coupled to the front and rear crossbeams such that said track support beam can pivot about a first axis of rotation parallel to a longitudinal axis of the track support beam, thereby allowing the first track assembly to move generally upwardly and downwardly in the opposite direction of the second track assembly. The first track assembly is pivotably coupled to the track support beam such that the first track assembly is pivotable about a second axis of rotation approximately perpendicular to the first axis of rotation and the second track assembly is pivotably coupled to the track support beam such that the second track assembly is pivotable about third axis of rotation approximately perpendicular to the first axis of rotation.
