Which part of the grader's blade is referred to as the leading end?

The leading end of the grader's blade is referred to as the toe. This part is crucial because it is the forward-most section of the blade during operation and is primarily responsible for cutting into the material being worked on, such as soil or gravel. The functionality of the toe affects how effectively the grader can shape and level surfaces.

Understanding the role of the toe helps operators recognize how to adjust the blade for different grading tasks and materials. For instance, if the toe is set too high, it may not engage the material effectively, leading to poor grading performance. Recognizing this specific terminology is essential for effective communication and operation in road grading tasks.
