Method and system of controlling a display device on a work machine having grade control

A method of controlling a work machine having a grade control system, the method comprising:

• receiving a first sensor signal from a first sensor coupled to a body frame of the work machine, the first sensor signal indicative of a body frame angle relative to a direction of gravity;
• receiving a second sensor signal from a second sensor coupled to an attachment coupled to the body frame, the second sensor signal indicative of an attachment angle relative to one of the body frame and the direction of gravity;
• receiving a target grade input;
• determining a cross slope of the attachment;
• determining a mainfall of the attachment;
• and
• controlling a display device to display a singular graphic of a position of the attachment relative to a target grade, the singular graphic representing the cross slope of the attachment and the mainfall of the attachment relative to the target grade, the singular graphic including
• a first graphic element representing the cross slope of the attachment,
• a second graphic element representing a body frame reference for the first graphic element, the relative positioning of the first graphic element relative to the second graphic element in a vertical direction representing the mainfall of the attachment relative to the body frame, and
• a third graphic element representing the target grade;
• and
• automatically controlling the position of the attachment based on the first sensor signal and the second sensor signal towards the target grade.
