Abstract
A ground opener unit for a seeding or planting unit includes an arm attachable to an implement frame and a disc rotatably mounted to the arm for forming a furrow in the ground. A scraper assembly includes a scraper plate defining a scraper edge for contacting and scraping a surface of the disc. The scraper plate defines a mounting region remote from the edge. A scraper plate mount secures the scraper plate adjacent the disc and a resilient pad of material is interposed between the plate mounting region and the scraper plate mount. A spaced pair of fasteners extend through the mounting region to secure the scraper plate and resilient pad to the scraper plate mount. The fasteners are located in selected positions in the mounting region relative to the resilient pad such that the scraper plate is capable of being tilted or rocked when said scraper edge encounters irregularities thus assisting the scraper edge to follow the disc surface during use.
