Abstract: A load estimator is disclosed for use with a scraper. The load estimator may have a first sensor configured to generate a first signal indicative of a performance parameter of the scraper, a second sensor configured to generate a second signal indicative of a hydraulic pressure associated with a bowl of the scraper, and a controller in communication with the first and second sensors. The controller may be configured to classify a current segment of an ongoing work cycle based on the first signal. The controller may also be configured to selectively estimate a load of material contained with the bowl of the scraper based on the second signal only when the current segment is classified as a segment where the load can be reliably estimated.

Abstract: A control system includes a work implement positioning system for moving a work implement to a desired position. A sensor is associated with the work implement and configured to obtain position information of the work implement. An electronic controller is configured to initiate a timer when the work implement is placed in the predetermined position. The controller is further configured to upon expiration of the timer, cause the work implement positioning system to return the work implement to the desired position. The controller is further configured to determine that the work implement has returned to the desired position.
