An agricultural tillage implement with a hydraulic system coupled to actuators of foldable wing sections and to actuators of wheel assemblies associated with each wing section. The hydraulic system having a wing sensor detecting an inner wing section being folded and at least one valve coupled to the wing sensor. The valve being activated by the wing sensor enabling a hydraulic fluid flow to the actuators associated with the wheel assemblies of the wing sections causing the wheel assemblies associated with the wing sections to thereby retract.

1. An agricultural tillage implement, comprising: a main section including a pull hitch extending in a travel direction including a pair of spaced-apart stops;a plurality of foldable wing sections including: a first left wing section pivotally coupled to the main section, the first left wing section
1. An agricultural tillage implement, comprising: a main section including a pull hitch extending in a travel direction including a pair of spaced-apart stops;a plurality of foldable wing sections including: a first left wing section pivotally coupled to the main section, the first left wing section including a first left wing bracket positioned thereon;a second left wing section including a left hinged bracket and an associated left stop rod positioned next to the hinged bracket and extending a distance thereabove when the second left wing section is positioned in a working mode, the second left wing section pivotally coupled to the first left wing section via the left hinged bracket;a first right wing section pivotally coupled to the main section, the first right wing section including a first right wing bracket positioned thereon; anda second right wing section including a right hinged bracket and an associated right stop rod positioned next to the hinged bracket and extending a distance thereabove when the second right wing section is positioned in a working mode, the second right wing section pivotally coupled to the first right wing section via the right hinged bracket,wherein each of the foldable wing sections include an actuator for folding the associated wing section, the first left wing section pivotally connected to the second left wing section, the first right wing section pivotally connected to the second right wing section,wherein the second wing sections are foldable onto the first wing sections such that the stop rod on each second wing section contacts a frame of the associated first wing section when in a transport mode,wherein the first wing sections are foldable on to the second wing sections such that in a folded position in the transport mode, a portion of the first left wing bracket on the first left wing section and a portion of the first right wing bracket on the first right wing section contacts one of the stops to hold the first wing section and the second wing section in an upright but non-perpendicular position relative to the main section,wherein the second wing sections are perpendicular relative to the main section when both first wing sections and second wing sections are folded in the transport mode, andwherein the second wing sections are not parallel to their associated first wing sections when in the folded transport mode,a plurality of ground engaging tilling elements coupled to one of the main section and at least one of the plurality of foldable wing sections;a plurality of wheel assemblies, each wheel assembly including an actuator, the plurality of wheel assemblies including a first plurality of wheel assemblies associated with the main section and a second plurality of wheel assemblies associated with the plurality of wing sections; anda hydraulic system coupled to the actuators of the wing sections and the actuators of the wheel assemblies, the hydraulic system including: a wing sensor detecting the wing sections being folded; andat least one valve coupled to the wing sensor, the at least one valve being activated by the wing sensor enabling a hydraulic fluid flow to the actuators associated with the wheel assemblies of the wing sections causing the wheel assemblies associated with the wing sections to thereby retract. 2. The agricultural tillage implement of claim 1, wherein the at least one valve includes a first valve and a second valve, the first valve being coupled to the actuators associated with the wheel assemblies of the right wing sections causing the wheel assemblies associated with the right wing sections to thereby retract, the second valve being coupled to the actuators associated with the wheel assemblies of the left wing sections causing the wheel assemblies associated with the left wing sections to thereby retract. 3. The agricultural tillage implement of claim 2, wherein the first left wing section is an outer left wing section, the second left wing section is an inner left wing section, the first outer right wing section is an outer right wing section, and the second right wing section is an inner right wing section. 4. The agricultural tillage implement of claim 1, wherein the second wing sections are parallel to each other when in the transport mode. 5. The agricultural tillage implement of claim 1, wherein the wing sensor is triggered when the respective wings are at least approximately 10 degrees pivoted between the working mode and the transport mode. 6. The agricultural tillage implement of claim 5, wherein the wing sensor is triggered when the respective wings are raised by approximately 45 degrees of rotation. 7. The agricultural tillage implement of claim 1, wherein as the implement transitions between the transport mode and the working mode the wing sensor detects an unfolding of the wing sections triggering a hydraulic fluid flow to the actuators associated with the wheel assemblies of the wing sections causing the wheel assemblies associated with the wing sections to thereby extend. 8. The agricultural tillage implement of claim 7, wherein the wheel assemblies of the wing sections remain extended until the implement is in the working mode, then they are adjusted by a depth control system. 9. The agricultural tillage implement of claim 7, wherein the wing sensor is triggered when the respective wings are at least approximately 10 degrees pivoted between the transport mode and the working mode as the wing sections are unfolded. 10. The agricultural tillage implement of claim 7, wherein the wing sensor is triggered when the respective wings are lowered by approximately 45 degrees of rotation. 11. The agricultural tillage implement of claim 1, wherein the actuators of the wheel assemblies of the left wing sections are in a series hydraulic circuit, and the actuators of the wheel assemblies of the right wing sections are in a different series hydraulic circuit.
