Abstract
A machine for distributing a material through a working unit along a ground surface in a direction established by an external reference includes front and rear devices for moving the machine along the ground surface, a steering control unit that functions to controlling the steering of the front and rear devices and, mounted along one side, first, second, and third steering sensors. The first, second and third steering sensors generate output signals indicative of their position with respect to the external reference. A processor unit utilizes the output signals generated by the first, second, and third steering sensors in a predetermined manner to cause the steering control unit to direct the machine generally in the direction established by the external reference.
