Abstract
The present inventors have recognized that hydraulic cylinders for raising and lowering ground engaging tools of an implement can be synchronously controlled with respect to a prioritized primary set of tools, such as a section of tillage shanks for ripping compacted soil, which cylinder adjustment affects all other sections due to the arrangement of the primary set on the frame. A user can electronically command new ground engaging depths for the primary set and/or any secondary set of ground engaging tools. If the primary set is updated, the system can synchronously control the primary set and the other sections to adjust respective cylinders to achieve desired depths. However, if only a second set is updated, and not the primary set, the system can control only the second set to adjust its cylinder to the desired depth without affecting the primary set or any other second set.
