Multiple-section agricultural implement

摘要

A self-compensating multiple-section agricultural implement is disclosed. The agricultural implement includes a first ground-engaging tool coupled to a first frame section. A lift device in fluid communication with a hydraulic controller is coupled to the first frame section. The lift device is configured for raising and lowering the first frame section to move the first ground-engaging tool between a first ground-engaging tool transport position and a first pre-selected operating depth. A second frame section is coupled to the first frame section forward of the first ground-engaging tool. A second ground-engaging tool is coupled to the second frame section. An extendable and retractable cylinder is in fluid communication with the hydraulic controller and is coupled to the first frame section and the second frame section. The extendable and retractable cylinder is configured to move the second ground-engaging tool between a second ground-engaging tool transport position and a second pre-selected operating depth.
