Abstract

A double shoot coulter assembly for an agricultural implement includes a packer wheel. The packer wheel is disposed behind a soil engaging blade. The packer wheel is configured to press soil displaced by the soil engaging blade into trenches formed by the soil engaging blade and a disc blade. A centerline of the packer wheel extends adjacent to a soil displacing side of the soil engaging blade.

Claims

1. A double shoot coulter assembly for an agricultural implement comprising:

a support structure;

a disc blade rotatably mounted to the support structure, and configured to form a trench in a soil surface;

a soil engaging blade mounted to the support structure, the soil engaging blade comprising a first side adjacent to the disc blade, and a second side, opposite the first side, configured to remove soil from a side of the trench; and

a packer wheel disposed behind the soil engaging blade, and configured to press soil into the trench, wherein a centerline of the packer wheel extends adjacent to the second side of the soil engaging blade.

2. The double shoot coulter assembly of claim 1, wherein the packer wheel comprises an annular cavity extending about an outer circumference of the packer wheel, the cavity configured to direct soil into the trench.

3. The double shoot coulter assembly of claim 1, wherein a top portion of the packer wheel is cambered away from the disc blade.

4. The double shoot coulter assembly of claim 1, wherein an intersection of a longitudinal axis of the soil engaging blade and a rotational axis of the packer wheel forms an acute angle.

5. The double shoot coulter assembly of claim 1, wherein the packer wheel is positioned directly behind the soil engaging blade.

6. The double shoot coulter assembly of claim 1, wherein the packer wheel is toed outwardly relative to the disc blade and the soil engaging blade.

7. The double shoot coulter assembly of claim 1, wherein an intersection of a longitudinal axis of the soil engaging blade and the centerline of the packer wheel forms an acute angle.

8. A double shoot coulter assembly for an agricultural implement comprising:

a support structure;

a disc blade rotatably mounted to the support structure, and configured to form a first trench in a soil surface for depositing a first agricultural product;

a soil engaging blade mounted to the support structure, the soil engaging blade comprising a first side adjacent to the disc blade, and a second side, opposite the first side, configured to form a second trench within the first trench for depositing a second agricultural product; and

a packer wheel disposed behind the soil engaging blade and configured to direct soil into the first and second trenches, wherein a centerline of the packer wheel extends adjacent to the second side of the soil engaging blade.

9. The double shoot coulter assembly of claim 8, wherein a top portion of the packer wheel is cambered away from the disc blade.

10. The double shoot coulter assembly of claim 8, wherein the first agricultural product comprises a fertilizer.

11. The double shoot coulter assembly of claim 8, wherein the second agricultural product comprises a seed.

12. The double shoot coulter assembly of claim 8, wherein the packer wheel comprises an annular cavity extending about an outer circumference of the packer wheel, the cavity configured to direct soil into the first and second trenches.

13. The double shoot coulter assembly of claim 8, wherein the packer wheel is positioned directly behind the soil engaging blade.

14. The double shoot coulter assembly of claim 8, wherein an intersection of a longitudinal axis of the soil engaging blade and a rotational axis of the packer wheel forms an acute angle.

15. A double shoot coulter assembly for an agricultural implement comprising:

a packer wheel disposed behind a soil engaging blade, wherein the packer wheel is configured to press soil displaced by the soil engaging blade into trenches formed by the soil engaging blade and a disc blade, wherein a centerline of the packer wheel extends adjacent to a soil displacing side of the soil engaging blade.

16. The double shoot coulter assembly of claim 15, wherein a top portion of the packer wheel is cambered away from the disc blade.

17. The double shoot coulter assembly of claim 15, wherein the packer wheel is positioned directly behind the soil engaging blade.

18. The double shoot coulter assembly of claim 15, wherein an intersection of a longitudinal axis of the soil engaging blade and the centerline of the packer wheel forms an acute angle.

19. The double shoot coulter assembly of claim 15, wherein the packer wheel is toed outwardly relative to the disc blade.

20. The double shoot coulter assembly of claim 15, wherein an intersection of a longitudinal axis of the soil engaging blade and a rotational axis of the packer wheel forms an acute angle.
