  • Digging control system
    Patent number: 8160783
    Abstract: A digging control system for use with a machine having a work implement is disclosed. The digging control system may have a sensing system configured to generate a signal indicative of a loading of the work implement. The digging control system may also have a controller. The controller may be configured to determine the loading of the work implement based on the signal. Additionally, the controller may be configured to initiate tilting of the work implement in response to a determination that the loading of the work implement exceeds a threshold loading. The work implement may not be substantially lifted during this tilting of the work implement. The controller may also be configured to monitor a tilt angle of the work implement. Additionally, the controller may be configured to cease tilting of the work implement when the tilt angle of the work implement substantially equals a threshold tilt angle.
