Rotating toolbar with double rod cylinder
In one embodiment, an implement comprising a center section and a pair of wing sections, each of the sections comprising a pair of parallel frame members pivotably coupled to each other, wherein one of the frame members comprises a toolbar; and a plurality of hydraulic cylinders enabling rotational movement between the parallel frame members, wherein the hydraulic cylinders of the wing sections comprise double rod cylinders and the hydraulic cylinders of the center section comprises single rod cylinders.
1. A system, comprising:
a control system;
a center section and a pair of wing sections, each of the sections comprising a pair of parallel frame members pivotably coupled to each other, wherein one of the frame members of the pair of parallel frame members comprises a toolbar; and
a plurality of hydraulic cylinders enabling rotational movement between the parallel frame members, wherein the hydraulic cylinders of the wing sections comprise double rod cylinders and the hydraulic cylinders of the center section comprises single rod cylinders,
the control system configured to cause the double rod cylinders to rotate the toolbars of the wing sections to multiple operational positions and to cause the single rod cylinders to rotate the tool bar of the center section to a subset of the multiple operational positions by changing a respective state of the double rod and single rod cylinders.
2. The system of claim 1 , wherein the control system comprises at least one controller and one or more control valves that are coupled to the double rod and single rod cylinders.
3. The system of claim 1 , wherein for each of the wing sections, the control system is further configured to cause the double rod cylinders to rotate the toolbar of the wing section to an approximately zero degree angle relative to a frame of the other frame member of the wing section based on a received input.
4. The system of claim 1 , wherein for each of the wing sections, the control system is further configured to cause the double rod cylinders to rotate the toolbar of the wing section to an intermediate angle relative to a frame of the other frame member of the wing section based on a received input.
5. The system of claim 1 , wherein for each of the wing sections, the control system is further configured to cause the double rod cylinders to rotate the toolbar of the wing section to an approximately ninety-degree angle relative to a frame of the other frame member of the wing section based on a received input.
6. The system of claim 1 , wherein for the center section, the control system is further configured to cause the single rod cylinders to rotate the toolbar of the center section to an approximately zero degree angle between the toolbar of the center section and a frame of the other frame member of the center section based on an input.
7. The system of claim 1 , wherein for the center section, the control system is further configured to cause the single rod cylinders to rotate the toolbar of the center section to an intermediate angle between the toolbar of the center section and a frame of the other frame member of the center section based on an input.
8. The system of claim 1 , wherein the control system is further configured to cause the single rod cylinders to rotate the toolbar of the center section to the subset of operational positions concurrently with causing the double rod cylinders to rotate the toolbars of the wing sections to the corresponding rotations.
9. The system of claim 1 , further comprising:
plural wheels between the pair of frame members, the wheels coupled to the frame member that is parallel to the toolbar; and
plural row units coupled to the toolbar.
10. A computer-implemented method for operating an implement, comprising:
at a controller:
receiving a first input;
based on the first input:
causing rotation of a toolbar of a center section of the implement through a first range of operational angles by actuating plural single rod cylinders that couple the toolbar to a frame member of the center section while causing rotation of a toolbar of a wing section through approximately the first range of operational angles by actuating plural double rod cylinders that couple the toolbar of the wing section to a frame members of the wing section;
receiving a second input; and
based on the second input:
while the toolbar of the center section is at a fixed position, causing the rotation of the toolbar of the wing section through approximately ninety-degrees by actuating the plural double rod cylinders.
