Title: Steering system for an articulated tracked combine

Abstract: One aspect of the present invention relates to a steering system for an articulated tracked combine composed of (i) a forward unit having a pair of differentially-connected powered non-steering wheels or tracks and (ii) a tracked rearward unit having powered steerable tracks. This steering system includes a pivoting articulation joint interconnecting the forward unit and the rearward unit. The rearward unit is fitted with a differential tracked steering system in steering connection with an operator steering wheel for steering of the articulated tracked combine. Optionally, such novel steering system includes a pair of steering articulation cylinder assemblies connected between the forward unit and the rearward unit. An angle sensor is mounted at the joint for sensing the relative position of the forward unit and the rearward unit. Another sensor is mounted at the steering wheel to sense its position. A controller is connected with the angle sensor and with the steering wheel sensor for monitoring their concordance and for activating the steering articulation cylinder assemblies when the concordance varies by a threshold value in order to re-establishes the concordance within the threshold value.
