Abstract
A furrow opener apparatus comprises a disc rotatably attached to the apparatus such that when the disc engages the ground, a furrow is formed adjacent to a trailing face of the disc. A scraper has a scraper blade oriented substantially parallel to the trailing face of the disc, and mounted such that the scraper blade is oriented in close proximity to or touching a lower portion of the trailing face adjacent to an outer edge of the disc. The scraper is adjustably attached to the apparatus such that the scraper blade can be moved inward along the trailing face of the disc as the disc wears while being maintained substantially parallel to the trailing face of the disc and in close proximity to or touching the trailing face of the disc. A delivery tube for agricultural material can be attached to the apparatus so that it moves in conjunction with the scraper, and the scraper can be biased against the face of the disc.
