<p>An agricultural implement (10, 210) is disclosed. The agricultural implement (10, 210) is adapted to be moved by a vehicle in a forward direction of travel. The agricultural implement (10, 210) comprising: a first frame section (20, 220); a first ground-engaging tool (30, 230) coupled to the first frame section (20, 220); a controller; a lift device (55, 255) in communication with the controller and coupled to the first frame section (20, 220), the lift device (55, 255) configured for raising and lowering the first frame section (20, 220) with respect to the ground (45, 245) to move the first ground-engaging tool (30, 230) between a first ground-engaging tool (30, 230) transport position (57, 257) and a first pre-selected operating depth (58, 258). At least a second frame section (65, 85, 265, 285) is coupled to the first frame section (20, 220) forward or rearward of the first ground-engaging tool (20, 220). At least a second ground-engaging tool (70, 90, 270, 290) is coupled to the at least second frame section (65, 85, 265, 285). At least one extendable and retractable actuator in communication with the controller ist coupled to the first frame section (20, 220) and the at least second frame section (65, 85, 265, 285), the actuator configured to move the at least second ground-engaging tool (70, 90, 270, 290) between a at least second ground-engaging tool transport position (82, 102, 282, 302) and a at least second pre-selected operating depth (83, 103, 283, 303). The agricultural implement (10, 210) is an improved self-compensating multiple-section agricultural implement (10, 210).</p> |
