What is the purpose of cleaning the outer sides of the trench with the bottom of the bucket?

The purpose of cleaning the outer sides of the trench with the bottom of the bucket primarily revolves around ensuring the trench area is clean and neat. When the outer sides of the trench are cleaned, it helps in maintaining the integrity of the trench itself, preventing loose debris or loose soil from falling back into the trench. A clean trench area is crucial for several reasons: it ensures the safety of personnel working around the trench, facilitates any subsequent work in or around the trench, and contributes to a more professional appearance of the job site.

In addition to cleanliness, while the efficiency of dirt removal and saving time may be secondary benefits of performing this task, they do not encapsulate the primary objective, which focuses on the condition and safety of the trench area. Reducing equipment wear is also a consideration, but it doesn't directly tie into the specific task of cleaning the trench sides, which is more about the cleanliness and safety of the work environment.
