  • Patent number: 4723609
    Abstract: A scraper for use with a two point bucket hitch of a tractor. The scraper provides a resiliently deformable blade depending below a rigid blade so that the deformable blade might be independently used by regulating blade height above a surface. The scraper has a primary medial blade member with pivotally connected lateral wing blade members on each side, which may be independently moved. The lateral wings releasably carry inwardly projecting tines to releasably engage and support coherent masses of material such as baled hay. A releasably attachable bottom pan converts the blade structure to a bucket. The scraper is particularly adapted to move animal excrement over flat surfaces of agricultural structures for accumulation and remove it therefrom for disposition.
