In an embodiment, an agricultural implement includes a tool bar and a tool frame rotatably coupled to the tool bar. The agricultural implement also includes multiple row units coupled to the tool frame, and a frame actuator extending between the tool bar and the tool frame. The frame actuator is configured to rotate the tool frame between a lowered position that places each row unit in contact with soil and a transport position that raises each row unit above the soil. The frame actuator is also configured to transfer weight from the tool bar to the tool frame while the tool frame is in the lowered position. Each row unit includes a ground engaging tool configured to selectively engage and disengage the soil while the tool frame is in the lowered position.

1. An agricultural implement, comprising: a tool bar;a tool frame rotatably coupled to the tool bar;a plurality of row units coupled to the tool frame; anda frame actuator extending between the tool bar and the tool frame, wherein the frame actuator is configured to rotate the tool frame between a lowered position that places each row unit in contact with soil and a transport position that raises each row unit above the soil, the frame actuator is configured to transfer weight from the tool bar to the tool frame while the tool frame is in the lowered position, and the weight transferred from the tool bar to the tool frame by the frame actuator is sufficient to maintain contact between each row unit and the soil without an additional biasing assembly extending between the tool bar and the tool frame;wherein each row unit comprises a ground engaging tool configured to selectively engage and disengage the soil while the tool frame is in the lowered position. 2. The agricultural implement of claim 1, wherein the frame actuator comprises a linear actuator extending between a first mounting bracket on the tool bar and a second mounting bracket on the tool frame. 3. The agricultural implement of claim 1, wherein the frame actuator comprises a hydraulic actuator. 4. The agricultural implement of claim 1, comprising a plurality of tool bars and a plurality of tool frames, wherein a frame actuator extends between each tool frame and a corresponding tool bar. 5. The agricultural implement of claim 4, wherein the plurality of tool bars comprises two first wing tool bars each having a first end and a second end, the first end being pivotally coupled to a tow bar assembly, and two second wing tool bars each coupled to the second end of a respective first wing tool bar, and wherein the plurality of tool frames comprises two first wing tool frames each coupled to a respective first wing tool bar, and two second wing tool frames each coupled to a respective second wing tool bar. 6. The agricultural implement of claim 1, wherein each row unit comprises a tool actuator coupled to the ground engaging tool and configured to transition the ground engaging tool between a working position in which the ground engaging tool engages the soil and a non-working position in which the ground engaging tool disengages the soil, while the tool frame is in the lowered position. 7. The agricultural implement of claim 1, wherein each row unit comprises a packer wheel configured to establish a penetration depth of the ground engaging tool into the soil, and wherein the frame actuator is configured to position the tool frame such that each packer wheel contacts the soil while the tool frame is in the lowered position. 8. The agricultural implement of claim 1, comprising a hitch assembly coupled to the tool bar, wherein the agricultural implement is configured to be towed by the hitch assembly. 9. An agricultural implement, comprising: a tool bar;a tool frame coupled to the tool bar;a plurality of row units coupled to the tool frame; anda frame actuator extending between the tool bar and the tool frame, wherein the frame actuator is configured to transition the tool frame between a lowered position that places each row unit in contact with soil and a transport position that raises each row unit above the soil, the frame actuator is configured to transfer weight from the tool bar to the tool frame while the tool frame is in the lowered position, and the weight transferred from the tool bar to the tool frame by the frame actuator is sufficient to maintain contact between each row unit and the soil without an additional biasing assembly extending between the tool bar and the tool frame;wherein each row unit comprises a ground engaging tool and a tool actuating cylinder configured to transition the ground engaging tool between a ground-engaged working position and a ground-disengaged non-working position, while the tool frame is in the lowered position. 10. The agricultural implement of claim 9, wherein the frame actuator comprises a hydraulic cylinder. 11. The agricultural implement of claim 9, wherein the frame actuator is configured to transition the tool frame between the lowered position and the transport position by rotating the tool frame upwardly with respect to the tool bar. 12. The agricultural implement of claim 9, wherein each row unit comprises a packer wheel configured to establish a penetration depth of the ground engaging tool into the soil, and wherein the frame actuator is configured to position the tool frame such that each packer wheel contacts the soil while the tool frame is in the lowered position. 13. The agricultural implement of claim 9, comprising a plurality of tool bars and a plurality of tool frames, wherein a frame actuator extends between each tool frame and a corresponding tool bar. 14. The agricultural implement of claim 9, comprising a hitch assembly coupled to the tool bar, wherein the agricultural implement is configured to be towed by the hitch assembly.
