Abstract: A method for reducing an overall transport profile of a multi-section tillage implement. The tillage implement may include a frame including a center frame section and at least one wing frame section. The tillage implement may include a plurality of ground-engaging tools pivotally mounted to the frame. The method may include pivoting each of the plurality of ground-engaging tools away from the ground surface from a ground-engaging position to a retracted position. The frame may be disposed at an initial height relative to the ground surface before pivoting. After pivoting, the frame may be lowered to a transport height relative to the ground surface. At least one wing frame section may be folded relative to the center frame section from an operating position to a transport position to reduce a width of the tillage implement in the widthwise direction.

Abstract: In one aspect, a piston assembly for a fluid-driven actuator may include a piston defining a passage extending between first and second chambers of the actuator. The piston assembly may further include a valve having a valve head and a valve stem. The valve may be positioned within the passage and slidable between an open position and a closed position. The valve stem may extend outward from the passage into the second chamber when the valve is positioned in the closed position. Additionally, the piston assembly may include a spring compressed between the valve head and the piston. The spring may be configured to bias the valve to the closed position. The valve may be configured to move to the open position when a pressure in the second chamber exceeds a pressure threshold or when the valve stem contacts a cylinder of the fluid-driven actuator.

Abstract: In one aspect, a system for monitoring soil conditions within a field may include an implement configured to be traversed across a field. The implement may further include a plurality of ground engaging tools pivotally coupled to the frame and a plurality of sensors. Each sensor may be configured to detect a parameter indicative of a current position of one of the plurality of ground engaging tools. Additionally, the system may include a controller configured to monitor a displacement of each ground engaging tool and determine a current global ground engaging tool displacement parameter for the implement based on the monitored displacements of the plurality of ground engaging tools. Additionally, the controller may be configured to identify a soil condition for a swath of the field being traversed by the implement based on a comparison between the current global ground engaging tool displacement parameter and a predetermined global displacement threshold.

Abstract: Systems, methods and apparatus are provided for managing implement weight. In some embodiments, a position sensor is used to determine a position of the wing section and a downforce applied to the wing is modified in order to lower the wing section. In some embodiments, the position sensor indicates the position of a wing wheel assembly of the wing section. In other embodiments, the position sensor indicates the position of a center wheel assembly of a center section of the implement.

Abstract: A towed implement, such as a cultivator is configured between an unfolded operational position and a folded transport position in which wing sections are pivoted about a vertical axis into a forward direction where they are alongside a telescoping tool bar. Sensors on the cultivator send signals initiating the folding/unfolding sequence to send commands through the implement controller to a tractor controller having a ISOBUS class 3 configuration. The tractor is commanded to forward and rearward movement in synchronism with the folding/unfolding process to steer wing supporting wheel assemblies toward the correct position for the intended transport direction.

Abstract: An agricultural implement including a frame, a hydraulic system, a controller and a plurality of sensors. The hydraulic system is coupled to the frame and has a plurality of hydraulic actuators fluidically coupled in a series arrangement. The controller is in control of the hydraulic system. The plurality of sensors have at least one sensor coupled to each of the plurality of hydraulic actuators. The sensors are in communication with the controller, with the controller executing the steps of receiving at least one signal from the sensors indicating a need to rephase the hydraulic actuators; and operating the hydraulic system to rephase the hydraulic actuators dependent upon the signal.

Abstract: An agricultural machine or implement has a main frame section and at least one wing section, each having lift cylinders. A main shank frame may be pivotally attached to the main frame section and may have hydraulically adjustable gauge wheels. Wing shank frames may be pivotally attached to the wing sections and may also have hydraulically adjustable gauge wheels. Bypass circuits may be used to individually adjust the lift cylinders and gauge wheel cylinders. A controller or controllers is used to purge air from the lift cylinders, gauge wheel cylinders, cylinders used to raise the shank frames for transport, and from the bypass circuits. The purge routine may be selectable as individual steps, hydraulic subsystem purges, or as one automatic purge routine.

Abstract: A harrow attachment for a tillage implement has a harrow drawbar, configured to mount to a frame member of the tillage implement, and at least one harrow rank having a rank bar supporting a plurality of harrowing tools oriented to extend away from the rank bar. An anti-tangle bracket assembly has a first pivot link coupled to the harrow drawbar and a second pivot link pivotally coupled to the at least one harrow rank. The first and second pivot links pivot about pivot axes with respect to one another within a pivotal range of movement of the at least one harrow rank from a first, extended position to a second, tripped position.
