Abstract
A work machine includes systems and methods for stability control and for calibrating the stability control. During operation the load on a work implement is detected and it is determined if the load is at or above a threshold value. A derated fluid output is determined if the load is at or above the threshold value. A control signal is output to the valve based on the derated fluid output. During calibration the pressure in a hydraulic cylinder is detected at one or more locations as a mechanical arm moves between a lower position and an upper position. One or more baseline values are established for the mechanical arm between the lower position and the upper position.
