摘要：
A self-compensating multiple-section agricultural implement is disclosed. Theagricultural implement includes a first ground-engaging tool coupled to afirst framesection. A lift device in fluid communication with a hydraulic controller iscoupled tothe first frame section. The lift device is configured for raising andlowering the firstframe section to move the first ground-engaging tool between a first ground-engagingtool transport position and a first pre-selected operating depth. A secondframe section is coupled to the first frame section forward of the firstground-engagingtool. A second ground-engaging tool is coupled to the second framesection. An extendable and retractable cylinder is in fluid communication withthehydraulic controller and is coupled to the first frame section and the secondframesection. The extendable and retractable cylinder is configured to move thesecondground-engaging tool between a second ground-engaging tool transport positionanda second pre-selected operating depth.
