Disc furrow opener scraper positioning system
First Claim
1. A furrow opener apparatus adapted for attachment to an implement for movement along the ground in an operating travel direction, the apparatus comprising:
- a disc rotatably attached to the apparatus in a generally upright orientation at an angle to the operating travel direction such that when a leading face of the disc engages the ground, a furrow is formed adjacent to a trailing face of the disc;
a scraper having a scraper blade oriented substantially parallel to the trailing face of the disc, and mounted such that the scraper blade is oriented in proximity to or touching a lower portion of the trailing face adjacent to an outer edge of the disc;
wherein the scraper is adjustably attached to the apparatus such that the scraper blade can be moved inward along the trailing face away from the outer edge of the disc while being maintained substantially parallel to the trailing face of the disc and in proximity to or touching the trailing face of the disc.

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.

14. A furrow opener apparatus adapted for attachment to an implement for movement along the ground in an operating travel direction, the apparatus comprising:
-
an arm adapted for pivotal attachment at a front end thereof to the implement;
a disc rotatably attached to a rear portion of the arm in a generally upright orientation at an angle to the operating travel direction such that when a leading face of the disc engages the ground, a furrow is formed adjacent to a trailing face of the disc;
a scraper having a scraper blade and attached to a scraper bracket;
wherein the scraper bracket is attached to the arm such that the scraper blade is oriented substantially parallel to the trailing face of the disc in proximity to or touching a lower portion of the trailing face adjacent to an outer edge of the disc;
wherein the attachment of the scraper bracket to the arm is adjustable such that the scraper bracket can be moved along the arm and can be locked to the arm in a desired location relative to the arm, such that the scraper blade can be moved inward along the trailing face as the disc wears and such that the scraper blade is maintained substantially parallel to the trailing face of the disc and in proximity to or touching the trailing face of the disc as the scraper blade moves inward. - View Dependent Claims (15, 16, 17, 18, 19)
