Abstract
A dual path agricultural machine including a control system having a number of input sensors, status sensors, and output sensors, and a controller configured to operate the dual path machine in a stability control mode and a selective rear-steer engagement and actuation mode. In the stability control mode, the controller adjusts an actual drive output of the dual path machine according to data received from the input sensors and feedback received from the output sensors so as to reduce a difference between the actual drive output and a desired drive output. In selective rear-steer engagement and actuation mode, the controller engages rear-steer mechanisms with caster wheels of the dual path machine and actuates the caster wheels via the rear-steer mechanisms if a criterion is satisfied. The controller disengages the rear-steer mechanisms from the caster wheels or does not actuate the caster wheels if the criterion is not satisfied.
