Abstract: A slue position sensing system and method of modifying a machine to include such a slue position sensing system are disclosed. The slue position sensing system may include a swing sensor housing disposed between a swing motor and a swing drive. The swing sensor housing may be coupled to a rotary position sensor that indirectly detects rotation of the target gear or a speed sensor that directly detects rotation of the target gear. For embodiments with no target gear, but with upper and lower frames rotatably coupled together by a ring gear and a swing gear, the sensor may be a rotary position sensor mounted to a slip ring assembly and magnet that are connected to a hydraulic swivel between the upper and lower frames or the sensor may be a speed sensor that detects rotation of the swing gear. The sensors generate a signal that is communicated to a controller or an ECM that accurately reflects the angular movement imparted to the work implement by the swing drive.

Abstract: A method and apparatus for operating an implement for a machine is provided. The machine has a body, a pump, an implement, an operator station, a first operator input device, and a second operator input device. The pump is mounted to the body and has a first operating range. The implement is mounted to the body and coupled to the pump. The operator station is positioned on the body. The first operator input device is located within the operator station and operable to control the implement over the first operating range and the second operator input device is positioned external to the operator station and operable to control the implement over a second operating range. The second operating range is less than the first operating range.
