At what angle is the blade set for marking and ditching cuts?

The appropriate angle for setting the blade for marking and ditching cuts is 45 degrees. This angle is optimal because it allows the blade to effectively slice through the material, creating a well-defined edge for establishing grade lines or performing ditching operations. When the blade is set at 45 degrees, it strikes a balance between the surface being cut and the depth required for the ditch or mark, ensuring a clean and accurate cut without excessive dragging or resistance from the material being moved. This angle provides the best control and maneuverability while operating the grader, contributing to more efficient grading and ditching practices.
