  • Front park brake protection controls
    Patent number: 9266513
    Abstract: A system and method are provided for enhancing the slope-holding capability of an earth-moving machine. The machine includes a plurality of ground-engaging elements and a first parking brake configured to brake a first subset of the plurality of ground-engaging elements. A second parking brake is mounted and is configured to brake a second subset of the plurality of ground-engaging elements. A brake controller is configured to sense engagement of the first parking brake and to engage the second parking brake when the first parking brake is engaged only if one or more machine state criteria are also met. In an embodiment, the one or more machine state criteria include zero machine speed, neutral transmission state, and a machine slope that exceeds a predetermined threshold slope.
