Abstract

In an embodiment, an agricultural 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, where the shank is coupled to the parallel linkage. The agricultural implement also includes a packer wheel configured to control a depth of a valley opened in a soil region by the ground engaging tool and is configured to pack the soil region as the implement is towed through a field and a soil shaping assembly disposed between the ground engaging tool and the packer wheel, wherein the soil shaping assembly is configured to close the valley prior to packing by the packer wheel.

Claims

1. A method, comprising:

mounting a frame to a linkage;

mounting a shank to the linkage;

mounting a ground engaging tool to the shank, wherein the shank is coupled to the linkage via a shank adapter;

mounting a packer wheel assembly to the linkage, wherein the packer wheel assembly is configured to control a position of the ground engaging tool and to pack a soil region as an implement is towed through a field;

wherein a hydraulic cylinder extends between the frame and the shank adapter, wherein the hydraulic cylinder is configured to control a downward force of the ground engaging tool, the packer wheel, or a combination thereof; and

mounting a soil shaping assembly to the packer wheel assembly between the ground engaging tool and the packer wheel assembly, wherein the soil shaping assembly is configured to close a valley created by the ground engaging tool prior to packing by the packer wheel assembly.

2. The method of claim 1, wherein mounting the soil shaping assembly comprises mounting a disk to the packer wheel assembly.

3. The method of claim 1, wherein mounting the soil shaping assembly comprises mounting a plurality of disks to the packer wheel assembly.

4. The method of claim 1, wherein mounting the soil shaping assembly comprises mounting a harrow tine to the packer wheel assembly.

5. The method of claim 1, wherein mounting the soil shaping assembly comprises mounting a plurality of harrow tine to the packer wheel assembly.

6. The method of claim 1, wherein mounting a packer wheel assembly comprises mounting the packer wheel assembly to a parallel linkage assembly configured to maintain a constant orientation of the ground engaging tool with respect to the packer wheel.

7. The method of claim 1, wherein mounting a soil shaping assembly comprises coupling a biasing member to a second ground engaging tool.
