Manually adjustable packer wheel seeding system and method
An implement includes a frame configured to couple to a tool bar, a linkage coupled to the frame, and a ground engaging tool extending from a shank, wherein the shank is coupled to the linkage. The implement also includes a packer wheel configured to control a position of the ground engaging tool, wherein the packer wheel is positioned behind the ground engaging tool when the ground engaging tool is engaging the soil. Further, the implement includes an adjustment mechanism configured to allow for adjustment of the distance between the packer wheel and the ground engaging tool.
1. A seeding implement, comprising:
a frame configured to couple to a tool bar;
a linkage coupled to the frame;
a ground engaging tool extending from a shank, wherein the shank is coupled to the linkage and configured to be automatically displaced upon encountering an obstruction;
a packer wheel configured to control a position of the ground engaging tool, wherein the packer wheel is positioned behind the ground engaging tool when the ground engaging tool is engaging soil; and
an adjustment mechanism configured to permit manual adjustment of a distance between the packer wheel and the ground engaging tool, wherein the adjustment mechanism comprises an axle of the packer wheel and a mechanical member providing multiple discrete locations, wherein the axle is mountable to each of the multiple discrete locations, and each discrete location corresponds to an aperture in a packer wheel mounting structure.
2. The implement of claim 1 , wherein the ground engaging tool is mounted on a movable structure that permits the ground engaging tool to move rearwardly and upwardly upon encountering an obstruction.
3. The implement of claim 2 , wherein a forward-most position permitted by the adjustment mechanism is sufficiently rearward to permit the ground engaging tool to clear the packer wheel when displaced rearwardly and upwardly upon encountering an obstruction.
4. The implement of claim 2 , wherein the packer wheel is configured to maintain contact with the ground as the obstruction passes beneath the implement.
5. The implement of claim 1 , wherein the ground engaging tool comprises a hoe opener.
6. A seeding implement, comprising:
a frame configured to couple to a tool bar;
a linkage coupled to the frame;
a ground engaging tool extending from a shank, wherein the shank is coupled to the linkage, the ground engaging tool being mounted on a movable mechanism that allows the ground engaging tool to more rearwardly and upwardly upon encountering an obstruction;
a packer wheel configured to control a position of the ground engaging tool, wherein the packer wheel is positioned behind the ground engaging tool when the ground engaging tool is engaging soil; and
an adjustment mechanism configured to permit manual adjustment of a distance between the packer wheel and the ground engaging tool, wherein the adjustment mechanism comprises an axle of the packer wheel and a mechanical member providing multiple discrete locations, wherein the axle is mountable to each of the multiple discrete locations, and each discrete location corresponds to an aperture in a packer wheel mounting structure.
7. The implement of claim 6 , wherein a forward-most position permitted by the adjustment mechanism is sufficiently rearward to permit the ground engaging tool to clear the packer wheel when displaced rearwardly and upwardly upon encountering an obstruction.
8. The implement of claim 6 , wherein the packer wheel is configured to maintain contact with the ground as the obstruction passes beneath the implement.
9. The implement of claim 6 , wherein the ground engaging tool comprises a hoe opener.
