Abstract
A milling machine, system, and method for implementing an exit cut operation raises a rotor from a state where the rotor contacts ground surface material responsive to a control input at an operator control interface of the milling machine. The rate at which the rotor is raised can increase as the rotor is raised. When the rotor is determined to have reached a top surface of the ground surface material the rotor can be raised at a maximum rate.
