Abstract: A screed assembly is disclosed. The screed assembly has a screed frame that includes a main screed. Attached to the main screed is a drop arm that is used to attach the screed assembly to a work machine. An actuator device of the screed assembly adjust the main screed from a neutral position to a nulled position by rotating the main screed around an axis of the pivot pin. The screed assembly may further include a controller that determines whether the main screed is in the neutral position and adjust the main screed to the nulled position by sending a null adjustment signal to the actuator device, and the actuator device moving the main screed from the neutral position to the nulled position in response to the null adjustment signal.
