Abstract

A control system for an extendable screed includes a first input device configured to set a speed limit for the extendable screed, a second input device configured to vary a speed of the extendable screed within the speed limit. The controller further includes, a third input device configured to govern a relationship between a speed of the extendable screed and a relative position of the second input device. The control system further includes a controller configured to receive inputs from the first, the second, and the third input devices and output a command signal to move the extendable screed relative to the main screed.
