ABSTRACT:
The center-pivot vehicle has forward and rearward sections with traversing means for traversing terrain. A rotary actuator connects the forward and rearward sections. Rotation of the rotary actuator articulates the forward and rearward sections relative to each other for steering the vehicle. The present invention also includes a method for controlling articulation of a center-pivot vehicle which includes connecting first and second sections of the center-pivot vehicle together with a rotary actuator, powering the rotary actuator with an engine and providing a steering input by an operator for operating the rotary actuator for rotating the rotary actuator and articulating the first and second sections of the vehicle relative to each other for turning the vehicle.
