  • Patent number: 4452315
    Abstract: Disclosed is an apparatus for deflecting straw and other debris from in front of a soil opening implement used in farming. The straw and debris deflector is particularly useful where the soil is generally not tilled. The straw and debris deflector includes an adjustable bracket which extends forward of the soil opening disk of the implement. Extending downwardly from the end of the bracket is a flexible oscillating tine. The tine rubs along the surface of the ground immediately in front of the soil openers to collect and deflect straw and other debris. The flexible tine oscillates forwardly and backwardly and from side to side. Periodic flexing to one or the other side of the disk removes collected debris from in front of the tine.
