Abstract: In one aspect, the disclosure describes an apparatus that harvests crops as the apparatus moves in a direction of travel across a field. The apparatus includes a crop harvesting assembly configured as a line of implements, the line being transverse to the direction of travel. First and second devices for adjusting a vertical position of left and right sides of the apparatus, respectively, are independently operable. Adjustment of a vertical position of at least one of the left and right sides of the apparatus results in tilting the line of implements relative to a horizontal plane defined at a ground surface under left and right ground contacting elements. In other aspects, a method and system are disclosed for automatically positioning a line of implements of an apparatus to follow a ground surface proximate the line of implements.

Abstract: A beach cleaner that is simple in configuration and light in weight and can be manufactured at a low cost. The beach cleaner is easy with regard to maintenance and inspection and can efficiently reclaim various kinds of refuse scattered on a beach. A beach cleaner includes a traveling body with ski members disposed at four corner portions of a frame having a substantially quadrangular shape. The beach cleaner is towed along a surface F of sandy soil by a traction vehicle R. A bar-like scraper is provided at a lower portion of a front portion of the traveling body and extends in a widthwise direction of the traveling body through a scraper supporting member for scraping up refuse on the sandy soil while the traveling body is operating. A refuse reclamation section is provided on the traveling body rearwardly of the bar-like scraper for collecting pieces of refuse scraped up and thrown rearwardly by the bar-like scraper onto a net member.
