Abstract: A motor grader is provided having cross slope cut angle control for providing accurate cuts generally, and particularly while the machine is travelling in other than a straight and level fashion. A controller is configured to adjust the cross slope angle of the blade, so that the cross slope cut angle corresponds to a desired cross slope cut angle. The controller receives a signal indicative of the desired cross slope cut angle and executing a pure pursuit procedure to identify a blade cross slope angle to yield the desired cross slope cut angle. The pure pursuit procedure includes identifying a blade travel direction, and identifying a horizontal component thereof. The blade edge is projected onto a plane perpendicular to the horizontal component of the blade travel direction, generating a slope function specifying the cross slope cut angle as a function of blade cross slope angle.
