Where is the deep digging attachment arm pinned?

The attachment arm for deep digging is designed to enhance the excavator's reach and digging capabilities. It is pinned directly at the end of the excavator arm, which allows for better leverage and increased depth of excavation. This positioning is crucial as it helps to distribute the load effectively during operation and provides maximum digging force right where it's needed. When the attachment is pinned at this location, it optimizes the hydraulic force generated by the machine, enabling it to dig deeper and more efficiently.

This design is especially important because it maintains the structural integrity and stability of the excavator while performing deep digs. By being mounted at the end of the arm, the attachment can pivot and operate flexibly, adapting to different digging tasks without compromising the machine's performance.
