Backhoe operations are mainly carried out below the ground, with digging as the main task. In this process, the excavator achieves efficient digging through the coordinated work of the dipper arm and bucket. When the bucket hydraulic cylinder and the connecting rod, and the dipper arm hydraulic cylinder and the dipper arm are all at a 90° angle, the maximum digging force and digging efficiency can be obtained. This specific angle setting ensures that the excavator's operating performance in backhoe operations is optimal.
