Abstract
An automatic monitoring and display system for use with a digging machine in order to excavate holes having a predetermined depth and an excavation slope pitch from ground level to hole depth. The machine has a boom, a dipper stick connected to the boom and a bucket at the end of the dipper stick, all interconnected by three pivots. Only two sensors are used to detect the position of the bucket relative to a zero reference signal which is stored in a processor. The operator of the machine has a console whereby to select an excavation depth as well as a slope pitch angle and the console will display to him the hole depth and the percentage pitch on the slope as the excavation proceeds. The operator can reset his zero reference signal at any time from anywhere.
