Abstract
A screed extension control system adapted for use on a screed assembly having a main screed, a main screed contact surface, a screed extension, and a screed extension contact surface. The screed extension control system comprises a slope actuator, a height actuator, at least one sensor, and a controller that is adapted to receive feedback from the at least one sensor. A virtual pivot point location is defined by a position where the main screed contact surface and the screed extension contact surface intersect. The controller causes at least one of the slope actuator and the height actuator to move between an extended position and a retracted position to control the position of the virtual pivot point location along the length of the main screed. A method for adjusting the screed extension position relative to the main screed.
