A system for detecting leaks in a hydraulic system. The system shuts down the hydraulic system if a leak is detected and notifies individuals in the area that a leak has occurred. The leak detection system has sensors for measuring hydraulic system parameters and a computer for detecting abnormalities in the system based on values returned by the sensors. Sensors used in the example leak detection system include and RPM pickup (100), a pressure transducer (110), a flow meter (108) and a hydraulic fluid level (103) and temperature switch (76). Outputs of the sensors are analyzed by the computer to determine if the hydraulic system has a leak. If a leak is detected, the computer sends response signals to a device for engaging or disengaging the prime mover from the hydraulic pump and to another device for actuating a valve to stop hydraulic fluid flow from the reservoir. The computer may also send indicator signals to a display console for activating a warning light, a buzzer or a display.
