Dual track

摘要

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.

1. A track system for a farm implement including an undercarriage including at least a front crossbeam and a rear crossbeam, comprising:
first and second dual track propulsion systems, wherein the first and second dual track propulsion systems are located on opposite sides of the farm implement, each dual track propulsion system comprising: a first track assembly and a second track assembly, the first track assembly including at least a first track frame, at least two first wheels, and a first track belt looped around said first wheels, and the second track assembly including at least a second track frame, at least two second wheels, and a second track belt looped around said second wheels, wherein the first and second track assemblies are laterally spaced apart; and a track support beam coupled to the first track frame of the first track assembly and the second track frame of the second track assembly and including a first end and a second end, wherein the first end is pivotably coupled to the front crossbeam and the second end is pivotably coupled to the rear crossbeam such that said track support beam pivots about a first axis of rotation and causes the first track assembly to move in the opposite direction of the second track assembly, wherein 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 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 perpendicular to the first axis of rotation.
