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.

After a control system receives a verification from the operator that the machine may operate outside the worksite area and within an outer boundary defined by the first maneuvering distance, a worksite perimeter is defined to include the path, and a geofence for the machine is determined to substantially overlay the outer boundary.
