摘要：
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.
