Abstract: A system includes an agricultural implement and a tractor for pulling the implement. The implement includes a frame supporting at least one ground-engaging tool and at least one image imager system coupled to a longitudinal end of the frame. The tractor includes a central controller, wherein the at least imager system is operably coupled to the central controller. The central controller is configured to receive image data from an imager system, analyze the image data to identify at least one mark formed in a soil surface, and responsive to identifying the at least one mark, cause feedback regarding a current position and orientation of the implement and an ideal position and orientation of the implement to be output via an input/output device.

Abstract: An agricultural implement includes a longitudinally extending frame configured to be coupled to a tractor, a first elongate toolbar extending laterally outward from the frame and carrying a first row unit, a second elongate toolbar extending laterally outward the frame and carrying a second row unit, a first sensor configured to sense a position of the first row unit relative to ground, a second sensor configured to sense a position of the second row unit relative to the ground, a first actuator configured to rotate the first elongate toolbar relative to the frame based at least in part on the sensed position of the first row unit, and an actuator configured to rotate the second elongate toolbar relative to the frame based at least in part on the sensed position of the second row unit. Control systems and related methods are also disclosed.

Abstract: In one embodiment, an in-line tandem axle assembly comprising: a tandem wheel arm; a pair of wheel connecting assemblies, each comprising a hub and a spindle; a pair of mounts coupled respectively to the pair of wheel connecting assemblies; a pair of wheels coupled respectively to the pair of wheel connecting assemblies, the pair of wheels separated by the tandem wheel arm and in a same fore-and-aft position; and plural pairs of parallel links of equal length pivotably mounted to the pair of mounts and pivotably mounted to the tandem wheel arm.

Abstract: In one embodiment, an in-line tandem axle assembly comprising: a tandem wheel arm (46); a pair of wheel connecting assemblies (44A, 44B), each comprising a hub (60A, 60B) and a spindle (58A, 58B); a pair of mounts (50A, 50B) coupled respectively to the pair of wheel connecting assemblies; a pair of wheels (52A, 52B) coupled respectively to the pair of wheel connecting assemblies, the pair of wheels separated by the tandem wheel arm and in a same fore-and-aft position; and plural pairs of parallel links (48A, 48B) of equal length pivotably mounted to the pair of mounts and pivotably mounted to the tandem wheel arm.

Abstract: 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.

Abstract: An implement includes an implement frame having an integrated elongate toolbar carrying at least one row unit, at least one wheel coupled to the implement frame and defining an axis of rotation, a sensor configured to sense a position of the at least one row unit relative to the ground, and a control system. The control system is configured to receive a signal related to the sensed position of the at least one row unit relative to the ground and cause a lift system to raise or lower a portion of the implement frame connected to the lift system to rotate the implement frame about the axis of rotation of the at least one wheel based at least in part on the signal. Control systems and related methods are also disclosed.

Abstract: A system includes a tractor comprising a lifting hitch, and an implement comprising an implement frame carried by the lifting hitch. The implement frame has an integrated elongate toolbar carrying at least one row unit. A sensor is configured to sense a position of the at least one row unit relative to the ground. A control system is configured to receive a signal related to the sensed position of the at least one row unit relative to the ground and cause the lifting hitch to raise or lower a portion of the implement frame connected to the lifting hitch relative to the tractor based at least in part on the signal. Control systems and related methods are also disclosed.
