15. A method of controlling a secondary conveyor of a cold planer, the method comprising:
providing a sensor on the secondary conveyor to sense a load of a material on the secondary conveyor;
the sensor sending information regarding the load to a controller; and
the controller controlling a speed of the secondary conveyor based on the information such that the secondary conveyor stops moving when the controller determines that there is no load on the secondary conveyor and when the controller determines that there is a load on the secondary conveyor the controller speeds up the secondary conveyor.
