Abstract:
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; and a 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.
