What is a potential hazard if the visibility from the operator's seat is poor?

When visibility from the operator's seat is poor, it significantly impacts grading accuracy. The operator needs to clearly see the work area, including the surface of the road, any obstacles, and the position of the grader blade in relation to the ground. Limited visibility can lead to misjudgments about the depth and angle of grading, resulting in an uneven surface, inadequate drainage, and other issues. This not only affects the quality of the work but can also pose safety risks for the operator and surrounding individuals.

While increased fuel consumption, increased tire wear, and decreased engine power may have other contributing factors, they are not directly related to the visibility from the operator's seat. Therefore, poor visibility is predominantly associated with reduced grading accuracy, making that the correct focus in this context.
