Abstract
An excavator comprises a control architecture having one or more actuators and one or more controllers. The one or more controllers are programmed to execute instructions. The instructions determine if there is a request to operate the excavator boom and the excavating implement in automatics mode. The instructions also receive target design surface data representing a target design surface of an excavating operation. The instructions still further receive an implement angle representing an operating angle of the excavating implement relative to the target design surface. The instructions also determine whether the implement angle is within an activation angle, determine whether the implement angle is outside of a deactivation angle, activate the excavating implement in the automatics mode when the implement angle is within the activation angle and the deactivation angle, and deactivate when the implement angle is outside of the deactivation angle subsequent to the automatics mode activation.
