Abstract: A method for controlling a bowl of a scraper is disclosed. The method includes receiving a signal from an input device, the signal is indicative of a mode of operation of the scraper, determining a cycle of operation of the scraper associated with the mode of operation, and controlling the bowl based in part on a sequence of parameter settings generated by a control system. The control system is configured to generate the sequence of parameter settings based in part on the cycle of operation of the scraper.

Abstract: A position determining system may include a hydraulic cylinder and a flow control device operatively connected to the hydraulic cylinder. A controller may be configured to supply an actuating signal to the flow control device. The controller may be configured to monitor a characteristic associated with the actuating signal, determine a hydraulic fluid flow rate in the hydraulic cylinder based on stored information relating the hydraulic fluid flow rate to the characteristic associated with the actuating signal, calculate a position of a component associated with the hydraulic cylinder based on the hydraulic fluid flow rate, and update the stored information when the determined position deviates from an actual position of the component.
