Adjustable packer wheel seeding system and method
In one embodiment, a seeding implement includes a frame configured to couple to a tool bar, a parallel linkage coupled to the frame, and a ground engaging tool extending from a shank, wherein the shank is coupled to the parallel linkage. The implement also includes a packer wheel configured to control a position of the ground engaging tool, wherein the packer wheel is positioned directly behind the ground engaging tool when the ground engaging tool is engaging a soil region. Further, the implement includes an adjustment mechanism configured to shift the packer wheel rearwardly upon the ground engaging tool encountering an obstruction and to shift the packer wheel forwardly after the obstruction has been passed by the ground engaging tool.
1. A system, comprising:
a packer wheel assembly configured to be disposed rearward of a hoe opener assembly, wherein the packer wheel assembly comprises a packer wheel mounted to a bracket, the packer wheel assembly controls a depth of a valley formed by a hoe opener of the hoe opener assembly while the hoe opener is in a ground engaging position, and the bracket is coupled to a packer wheel arm extending between the bracket and a linkage assembly; and
an adjustment mechanism that shifts the packer wheel horizontally from a first position directly behind the hoe opener to a second position rearward of the first position when the hoe opener encounters an obstruction and moves in a rearward direction toward a disengaged position, wherein the adjustment mechanism does not permit the packer wheel to move vertically.
2. The system of claim 1 , wherein the adjustment mechanism shifts the packer wheel horizontally from the second position to the first position as the hoe opener transitions to the ground engaging position after the obstruction has been passed by the hoe opener.
3. The system of claim 1 , wherein the adjustment mechanism shifts the packer wheel in the rearward direction such that the packer wheel does not contact the hoe opener as the hoe opener moves in the rearward direction toward the disengaged position.
4. The system of claim 1 , wherein the adjustment mechanism shifts the packer wheel in the rearward direction about 8 to about 12 inches.
5. The system of claim 1 , wherein the adjustment mechanism comprises a biasing member that urges the packer wheel in a forward direction.
6. The system of claim 1 , wherein the hoe opener and packer wheel are about 6 to about 10 inches apart when the hoe opener is in the ground engaging position.
7. The system of claim 1 , wherein the packer wheel assembly controls the depth of the valley between about 3 to about 6 inches.
8. A system comprising:
a packer wheel assembly configured to be disposed rearward of a hoe opener assembly, wherein the packer wheel assembly comprises a packer wheel mounted to a bracket, the packer wheel assembly controls a depth of a valley formed by a hoe opener of the hoe opener assembly while the hoe opener is in a ground engaging position, and the bracket is coupled to a packer wheel arm extending between the bracket and a linkage assembly; and
an adjustment mechanism that shifts the packer wheel only horizontally from a first position to a second position rearward of the first position when the hoe opener encounters an obstruction and moves in a rearward direction toward a disengaged position;
wherein the hoe opener and packer wheel are about 6 to about 10 inches apart when the hoe opener is in the ground engaging position.
9. The system of claim 8 , wherein the adjustment mechanism shifts the packer wheel horizontally from the second position to the first position as the hoe opener transitions to the ground engaging position after the obstruction has been passed by the hoe opener.
10. The system of claim 8 , wherein the adjustment mechanism shifts the packer wheel in the rearward direction such that the packer wheel does not contact the hoe opener as the hoe opener moves in the rearward direction toward the disengaged position.
11. The system of claim 8 , wherein the adjustment mechanism shifts the packer wheel in the rearward direction about 8 to about 12 inches.
12. The system of claim 8 , wherein the adjustment mechanism comprises a biasing member that urges the packer wheel in a forward direction.
13. The system of claim 8 , wherein the packer wheel maintains contact with a soil surface while the packer wheel is in the first and second positions.
14. The system of claim 8 , wherein the packer wheel assembly controls the depth of the valley between about 3 to about 6 inches.
15. A system comprising:
a packer wheel assembly configured to be disposed rearward of a hoe opener assembly, wherein the packer wheel assembly comprises a packer wheel mounted to a bracket, the packer wheel assembly controls a depth of a valley formed by a hoe opener of the hoe opener assembly to a depth of between about 3 to about 6 inches while the hoe opener is in a ground engaging position, and the bracket is coupled to a packer wheel arm extending between the bracket and a linkage assembly; and
an adjustment mechanism that shifts the packer wheel only horizontally from a first position to a second position rearward of the first position when the hoe opener encounters an obstruction and moves in a rearward direction toward a disengaged position.
16. The system of claim 15 , wherein the adjustment mechanism shifts the packer wheel in the rearward direction such that the packer wheel does not contact the hoe opener as the hoe opener moves in the rearward direction toward the disengaged position.
17. The system of claim 15 , wherein the adjustment mechanism shifts the packer wheel in the rearward direction such that the packer wheel does not contact the hoe opener as the hoe opener moves in the rearward direction toward the disengaged position.
18. The system of claim 15 , wherein the adjustment mechanism shifts the packer wheel in the rearward direction about 8 to about 12 inches.
19. The system of claim 15 , wherein the adjustment mechanism comprises a biasing member that urges the packer wheel in a forward direction.
20. The system of claim 15 , wherein the packer wheel maintains contact with a soil surface while the packer wheel is in the first and second positions.
