How high should the blade be positioned in the center windrow position?

• A. One-quarter the height of the windrow
• B. Half the height of the windrow
• C. Three-quarters the height of the windrow
• D. Equal to the height of the windrow

Answer: (B)

The blade should be positioned at half the height of the windrow when in the center windrow position for optimal grading effectiveness. This positioning allows for balanced dispersion of material, ensuring that as the grader moves, it can effectively cut and redistribute the material evenly on both sides of the windrow. By placing the blade at this height, the operator can maintain control over the material being graded and prevent overloading on either side, which could lead to uneven surfaces and potentially compromise the quality of the grade. Maintaining the blade at this specific height also reduces wear and tear on the grader's equipment, ensuring better longevity and performance. Additionally, it promotes efficient use of fuel and improves overall productivity since moving too high or too low could require additional passes to achieve a level surface. Therefore, positioning the blade at half the height strikes the right balance for effective road grading.
