Abstract
The moldboard support assembly for a motor grader reinforces the rear face of the moldboard by a series of vertical ribs. Upper and lower slide rails are secured to the ribs at a position outwardly of the rear face of the moldboard. This produces a series of gaps between adjacent ribs and between the rear face of the moldboard and the slide rails. These gaps allow material to clear away from the slide rails and thereby reduce bearing contamination of the slide rails.
