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.

Abstract: An implement system for a machine includes a primary blade and a secondary blade coupled to the primary blade through a linkage mechanism such that the secondary blade is trailing the primary blade. The implement system includes an actuator which controls a movement of the secondary blade. The implement system includes at least one position sensor which generates signals indicative of a position of the primary blade and a position of the secondary blade. The implement system further includes a controller which is in communication with the primary blade, the secondary blade and the position sensor. The controller receives the signals indicative of the position of the primary blade and the position of the secondary blade. The controller operates the actuator to control the movement of the secondary blade based on the position of the primary blade and secondary blade.

Abstract: A method of determining readiness of an emergency steering pump system is provided. The method may include the steps of detecting a startup condition; determining a standby pressure provided by a primary pump and a margin pressure to be provided by a secondary pump; engaging the secondary pump for a predefined duration based on the standby pressure and the margin pressure; and determining readiness based on a cumulative pressure of the standby pressure and the margin pressure as compared to a predefined threshold corresponding to load demand.
