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.
