In an exemplary embodiment, the seeding implement includes a ground engaging tool and a packer arm pivotally coupled to a packer support structure. The seeding implement also includes a packer wheel rotatably coupled to the packer arm, and configured to rotate across a soil surface to limit a penetration depth of the ground engaging tool into the soil. The seeding implement further includes a depth adjustment assembly including a slot within the packer support structure, a corresponding slot within the packer arm, and a fastener disposed through the slots. In this configuration, the penetration depth of the ground engaging tool is varied by adjusting a position of the fastener within the slots. ## Claims ### Claim 1 A seeding implement, comprising: a frame configured to be coupled to a tool frame; a linkage coupled to the frame and including a packer support structure, wherein the packer support structure includes a first slot; a ground engaging tool extending from a shank, wherein the shank is coupled to the linkage; a packer arm pivotally coupled to the packer support structure and including a second slot, wherein the second slot includes a plurality of indentations; a packer wheel rotatably coupled to the packer arm; and a fastener disposed through the first slot and the second slot. ### Claim 2 (depends on 1) The seeding implement of claim 1, wherein the fastener is configured to secure the packer arm to the packer support structure while in a locked position and to enable rotation of the packer arm with respect to the packer support structure while in an unlocked position. ### Claim 3 (depends on 1) The seeding implement of claim 1, wherein movement of the fastener between the indentations of the second slot varies a penetration depth of the ground engaging tool. ### Claim 4 (depends on 1) The seeding implement of claim 1, wherein the packer wheel is configured to rotate across a soil surface to limit a penetration depth of the ground engaging tool into the soil. ### Claim 5 (depends on 1) The seeding implement of claim 1, wherein the packer arm includes a guide plate positioned adjacent to the second slot, and wherein the guide plate is configured to block movement of the fastener out of an indentation of the plurality of indentations. ### Claim 6 A seeding implement, comprising: a frame configured to be coupled to a tool frame; a linkage coupled to the frame and including a packer support structure, wherein the packer support structure includes a first slot; a ground engaging tool coupled to the linkage; a packer arm pivotally coupled to the packer support structure and including a second slot; a packer wheel rotatably coupled to the packer arm, and configured to rotate across a soil surface to limit a penetration depth of the ground engaging tool into the soil; and a fastener disposed through the first slot and the second slot. ### Claim 7 (depends on 6) The seeding implement of claim 6, comprising a shank coupled to the linkage, wherein the ground engaging tool extends from the shank. ### Claim 8 (depends on 6) The seeding implement of claim 6, wherein the fastener is configured to secure the packer arm to the packer support structure while in a locked position and to enable rotation of the packer arm with respect to the packer support structure while in an unlocked position. ### Claim 9 (depends on 8) The seeding implement of claim 8, wherein the fastener remains disposed through the slots while in both the locked and unlocked positions. ### Claim 10 (depends on 6) The seeding implement of claim 6, wherein the slots are angled relative to an axis of rotation of the packer arm. ### Claim 11 (depends on 6) The seeding implement of claim 6, wherein the second slot includes a plurality of indentations configured to receive the fastener. ### Claim 12 (depends on 11) The seeding implement of claim 11, wherein movement of the fastener between the plurality of indentations varies the penetration depth of the ground engaging tool. ### Claim 13 (depends on 11) The seeding implement of claim 11, wherein the packer arm includes a guide plate positioned adjacent to the second slot, and wherein the guide plate is configured to block movement of the fastener out of an indentation of the plurality of indentations. ### Claim 14 A seeding implement, comprising: a frame configured to be coupled to a tool frame; a linkage coupled to the frame and including a packer support structure, wherein the packer support structure includes a first slot; a ground engaging tool coupled to the linkage; a packer arm pivotally coupled to the packer support structure and including a second slot, wherein the packer arm is configured to be coupled to a packer wheel to control a penetration depth of the ground engaging tool into the soil surface; and a fastener disposed through the first slot and the second slot. ### Claim 15 (depends on 14) The seeding implement of claim 14, wherein the fastener is configured to secure the packer arm to the packer support structure while in a locked position and to enable rotation of the packer arm with respect to the packer support structure while in an unlocked position. ### Claim 16 (depends on 15) The seeding implement of claim 15, wherein the fastener remains disposed through the slots while in both the locked and unlocked positions. ### Claim 17 (depends on 14) The seeding implement of claim 14, wherein the slots are angled relative to an axis of rotation of the packer arm. ### Claim 18 (depends on 14) The seeding implement of claim 14, wherein the second slot includes a plurality of indentations configured to receive the fastener. ### Claim 19 (depends on 18) The seeding implement of claim 18, wherein movement of the fastener between the plurality of indentations varies the penetration depth of the ground engaging tool. ### Claim 20 (depends on 19) The seeding implement of claim 19, wherein the packer arm includes a guide plate positioned adjacent to the second slot, and wherein the guide plate is configured to block movement of the fastener out of an indentation of the plurality of indentations.
