What tool is typically used for smoothing the surface of excavated areas?

The tool that is typically used for smoothing the surface of excavated areas is the grader. A grader is designed specifically for leveling and grading surfaces, making it an essential piece of equipment in construction and earthmoving operations. It features a long blade that can be adjusted to achieve the desired angle and depth, allowing for a smooth finish on surfaces such as roads, parking lots, or building sites.

While a rake can be useful for smaller scale projects, it lacks the ability to achieve the precision and efficiency required for larger excavated areas. A shovel is primarily used for digging and moving material rather than for smoothing surfaces. An excavator, while versatile in its ability to dig and move soil, is not primarily designed for the smoothing process, making the grader the best choice for this specific task.
