Why is the first surface cut important during excavation?

The importance of the first surface cut during excavation lies in its function as a guide for the bucket. Establishing a well-defined first cut allows the operator to create a clear reference point, which assists in maintaining the appropriate angle and depth throughout the excavation process. This initial cut provides a level surface that ensures consistent and accurate material removal, helping to achieve the desired grade or depth for the project.

By following the guidance of this initial cut, operators can work more efficiently and effectively, reducing the chances of over-excavation or under-excavation, and thus enhancing overall project quality. This technique is critical for ensuring that subsequent cuts and operations are performed correctly, leading to better control and results in the excavation process.
