Why should an operator adjust the grader's speed during different grading tasks?

An operator should adjust the grader's speed during different grading tasks primarily to maintain control and achieve the desired finish. Different grading operations may require varying levels of precision; for example, when performing a fine grading task, a slower speed allows the operator to have more control over the machine's movements, ensuring a smoother and more accurate surface. Conversely, when rough grading, a faster speed might be appropriate for effective material displacement. By adjusting speed appropriately, an operator can also adapt to changing conditions of the terrain and the material being graded, leading to better results in accordance with the specific requirements of the job. This attention to speed helps in achieving the desired grading finish efficiently and effectively.
