What should an operator do when fine grading an area to ensure an even surface?

When fine grading an area to ensure an even surface, the operator should focus on filling low areas effectively. Using accumulated material to fill these low areas while making a backward pass is a strategic approach. This method allows for better control over the soil distribution and ensures that the material is moved seamlessly into the depressions. By doing so, the operator can achieve a smoother and more level finish.

During grading, it is essential to address imperfections in the surface, and filling low areas while moving the machine in reverse helps to achieve this. This technique maximizes the effectiveness of the machine's capabilities and provides a precise and uniform surface, which is critical in construction and landscaping projects where a flat surface is required.

Other options, while relevant in certain grading scenarios, do not contribute as effectively to achieving an even surface. For instance, cutting high spots on the backward pass might help in some situations but does not specifically address the filling of low areas. Back-dragging the entire area simultaneously can often lead to uneven material distribution. Moreover, exclusively using the loader for grading limits the use of specialized techniques and attachments that might enhance the grading process.
