Estimating the term…
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.
An agricultural implement, comprising:
A method for changing ground engaging depths for tools of an agricultural implement, the agricultural implement comprising a frame supported by a plurality of wheels, a plurality of ground engaging tools supported by the frame, the plurality of ground engaging tools including a primary set and at least one secondary set, wherein each set includes a hydraulic cylinder arranged with respect to the frame for raising and lowering the set, and wherein each set is configured to engage the ground at a ground engaging depth when lowered to be in contact with the ground, and a hydraulic system comprising a pump configured to supply hydraulic fluid and a plurality of electronically controlled valves, wherein each electronically controlled valve is configured to meter hydraulic fluid with respect to a hydraulic cylinder, the method comprising:
