Furrow opening disc apparatus
First Claim
1. A furrow opener apparatus for attachment to an agricultural implement for depositing agricultural material in the soil, said apparatus comprising:
- a flat disc having a first side and a second side rotatably attached to said apparatus such that an axis of rotation of said flat disc is substantially perpendicular to a direction of travel of said implement;
a concave disc having a concave side and a convex side, said concave disc rotatably attached to said apparatus such that;
an axis of rotation of said concave disc is substantially perpendicular to the direction of travel of said implement;
a rear edge of said concave disc is behind a rear edge of said flat disc;
the concave side of said concave disc is facing said first side of the flat disc and an outer rim of said concave disc is in close proximity to or touching said first side of the flat disc;
means to introduce said agricultural material into an open area between the concave side of said concave disc and said first side of the flat disc.

Abstract
A furrow opener apparatus for attachment to an agricultural implement for depositing agricultural material such as seed and fertilizer in the soil. The apparatus comprises a flat disc rotatably attached to the apparatus such its axis of rotation is perpendicular to the direction of travel; a concave disc rotatably attached to the apparatus such that firstly the axis of rotation is perpendicular to the direction of travel, secondly the rear edge of the concave disc is behind the rear edge of the flat disc, thirdly the concave side of the concave disc is facing the flat disc and the outer rim of the concave disc is in close proximity to or touching the side of the flat disc; and means to introduce the agricultural material into the open area between the concave side of the concave disc and the side of the flat disc. The furrow opener requires less power to pull than present openers and penetrates un-tilled soil. A swivel mount and packer are provided for the furrow opener.
