Abstract
Apparatus and method provides for an improved steering system for an articulated vibratory roller machine. Steering can be accomplished without the use of a dedicated steering actuator. Instead, steering angles may be created by independently driving left and right side drum halves at the front and rear ends of the machine at different speeds and/or directions. This differential action creates the desired steering angle by rotating the front and back halves of the machine about a central articulated joint. As a result, a cost-effective and versatile solution that eliminates the need for conventional steering components and their associated disadvantages is provided.
