What is "blade angle"?

The term "blade angle" refers specifically to the angle at which the blade of a dozer is set to cut and move material. This angle is crucial because it determines the efficiency and effectiveness of the dozer in performing tasks such as grading, pushing, or spreading material. By adjusting the blade angle, operators can optimize the dozer’s performance based on the type of material being handled and the desired outcome of the task, allowing for better maneuverability and material control.

Other options such as the position of the dozer when stationary, the height at which the blade operates, or the width of the blade in relation to the dozer describe different aspects of dozer operation but do not specifically define "blade angle." The angle at which the blade is set is a key factor in how the dozer interacts with the ground and the material it is moving, making option A the correct choice.
