What is a common problem that can occur if the grader's blade is worn out?

When a grader's blade is worn out, it loses its sharpness and effectiveness in cutting and moving materials. This deterioration directly impacts the grader's ability to produce a smooth, level surface. As a result, the grading quality diminishes, leading to uneven surfaces that can cause issues such as water pooling or drainage problems. Uneven surfaces not only affect aesthetics but can also compromise the functionality of the road or worksite, leading to faster wear on vehicles and equipment. Thus, the common problem associated with a worn-out blade is indeed poor grading quality and uneven surfaces, which is critical for operational efficiency and road safety.
