Abstract
A system and process for controlling and actuating an excavation implement during excavation between an above-ground position and an operator specified below-ground position and for maintaining the specified below-ground position once achieved. The actuation of the excavation implement is regulated by use of an operator modifiable relationship between an engine operating speed and an actuator speed. The actuation of the excavation implement is further regulated by use of an operator modifiable relationship between an attachment drive speed and the actuator speed. A computer network controls the actuation of the excavation implement in response to inputs from the operator and feedback from the engine speed, the attachment drive speed, and an actuator position sensor as the excavation implement progresses through the earth. This results in the system maintaining the engine speed and the attachment drive speed at a desired output level when the excavation implement is subject to variations in loading while moving between the above-ground and below-ground positions.
