Abstract
A system and method for automatically adjusting the blade of a motor grader to an operator programmed blade position. The method includes the steps of: providing an electronic controller and blade controls having position sensors; monitoring the output of the position sensors to ascertain the position of the blade controls; receiving a first input signal for setting a memory blade position; determining the memory blade position based on the output of the position sensors; receiving a second input signal for requesting the memory blade position; determining the present blade position based on the output of the position sensors; and producing a control signal for actuating the blade controls to move the blade from the present blade position to the memory blade position.
