A screen system used in fluid channels has a scraper for removing debris from bars in a bar screenfield. The scraper is mounted to a top of a screen system. The scraper is lifted by a rake while simultaneously removing debris from the rake. Once the rake clears the scraper, the scraper returns to an original position. The scraper has arms that have wear plates with curvatures selected to avoid contact with the teeth. The scraper can have a cushioning device to lessen the impact of the scraper as it returns to a rest position.
