Single-pass, double-shoot opener for an agricultural implement
An opener for depositing fertilizer and seed in a single pass, double-shoot manner includes a rotating disc that cuts a furrow in a planting surface, a fertilizer tube that drops fertilizer into the furrow, and a trailing seed tube assembly, having a cutting edge, that cuts a vertically and horizontally offset trench in the furrow to form a seed bed in the planting surface onto which seed is deposited. The seed trench provides a seed bed that is offset from the bottom of the furrow to provide horizontal and vertical stratification of the seed and fertilizer.
1. A product dispensing apparatus for use with an agricultural implement, the agricultural implement including a rotatable disc for cutting a furrow into soil and a scraper blade adjacent the rotatable disc for keeping a leading face of the rotatable disc clear of debris, the product dispensing apparatus comprising:
a tubular member having a first end adapted to receive a product, a body adapted to pass the product, and a second end through which product exits the body, wherein the tubular member has a leading side and a trailing side;
a cutting member having a body attached to the leading side of the tubular member and adapted to cut a trench into a sidewall of the furrow; and
an adjustable mount for interconnecting the tubular member and the cutting member to the agricultural implement, the mount having a plurality of user selectable positions;
wherein movement of the mount between the plurality of user selectable positions adjusts the positions of the tubular member and the cutting member independent of a position of the scraper blade.
2. The apparatus of claim 1 wherein the cutting member is integrally formed with the tubular member.
3. The apparatus of claim 2 wherein the cutting member has a curved cutting edge that cuts the trench to be offset from a low point of the furrow.
4. The apparatus of claim 3 wherein the trench is cut horizontally and vertically offset from the low point of the furrow.
5. The apparatus of claim 1 wherein the cutting member has a cutting edge that is angled relative to an axis transverse to a line of travel of the apparatus, wherein the cutting is at an angle of approximately 12 degrees relative to the axis.
6. The apparatus of claim 1 wherein the cutting member includes a wear resistant element.
7. The apparatus of claim 6 wherein the wear resistant element is formed of carbide.
