    Abstract: A dual mode control system for a hydraulic circuit (200) having a variable displacement pump (216) includes at least two actuators, each controlled by a respective valve. The valves are connected in series with a pressure sensor (250) measuring a pressure of fluid between the first valve (224) and the second valve (234) and relaying a signal to the electronic controller (202). The electronic controller (202) operates in a first mode, varying the displacement of the pump (216) based on a command signal operating at least one of the valves, and operates in a standby mode, varying the displacement of the pump (216) based on the signal from the sensor, when both valves are in their respective neutral positions.

    Abstract: A machine control system for use with a machine having a power source and a transmission is disclosed. The machine control system may have a clutch configured to connect an output of the power source with an input of the transmission. The machine control system may also have a sensor configured to generate a signal indicative of a speed of the power source, and a controller in communication with the clutch and the sensor. The controller may be configured to vary an actuating force of the clutch based on the signal.
