The land roller can have a center section with a center roller, a hitch member connected to the center section, a first wing section pivotally connected at a first end to the center section and having a first wing roller, a second wing section pivotally connected at a first end to the center section and having a second wing roller. The at least one actuator can rotate a first rotating member that pivots the first wing section and rotate a second rotating member that pivots the second wing section to transform the land roller from the transport position into the operating position. The at least one actuator is unconnected to the first rotating member and the second rotating member.

A tool bar and hydraulic system for a large scale agricultural implement. The tool bar includes opposed pivotable wings that are extended in a field configuration and retracted in a transport configuration. In some embodiments, each pivotable wing includes two lift assist assemblies for aiding in the execution of turns in the field, and for aiding in the transport of the agricultural implement. The tool bar may be configured to compensate for twist of the pivotable wings when in the transport configuration. The hydraulic system is configured to stiffen the tool bar assembly for lift assist during field operation and to flex the tool bar into a folded configuration for transport.

The invention relates to an agricultural machine comprising two side units and a chassis that extends in a longitudinal direction and is equipped with two wheels, each side unit being fitted to pivot in relation to the chassis via a respective longitudinal joint around a folding axis parallel to a median plane of the chassis; each side unit comprising a tool unit connected to the chassis by a respective arm and being able to occupy a work position in which it rests on the ground and in which the length of the respective tool unit extends transversely to the longitudinal direction; each side unit being also able to occupy a transport position in which it is remote from the ground and in which the length and width of the respective tool unit are substantially parallel to the median plane. The machine comprises at least a tilter articulated with the chassis around at least one tilting axis oriented transversely to the longitudinal direction, and in the transport position of the side units, each tool unit is closer to the median plane than the respective arm.

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.

An agricultural apparatus includes a first main wing and at least one wheel on one side and a second main wing and at least one wheel on an opposite side. The first and second main wings are pivotable about respective axes of rotation between extended positions in which the first and second main wings extend laterally outward from respective opposite sides of the frame structure, and retracted, storage positions in which the first and second main wings extend generally along a length of the frame structure for shipping or transport. The first and second main wings include respective raised sections each configured to extend over a respective wheel on a corresponding side of the frame structure in the storage position. The raised sections each include a frame having a generally concave shape receiving a portion of one of the first and second wheels in the storage position.

In one aspect, a method for automatically actuating wing assemblies an agricultural implement associated with a work vehicle may include monitoring, with one or more computing devices, a first wing movement parameter associated with folding or unfolding a wing assembly of the agricultural implement during the performance of a wing movement operation. The method may also include determining, with the one or more computing devices, whether the first wing movement parameter satisfies a first condition associated with a first predetermined threshold value defined for the wing movement operation. The method may include, automatically initiating, with the one or more computing devices, movement of the work vehicle relative to a surface on which the work vehicle is supported to assist the folding or unfolding of the wing assembly during the performance of the wing movement operation when it is determined that the first wing movement parameter satisfies the first condition.

An agricultural implement includes a toolbar system having a toolbar frame, an elevator assembly, and a first wing on one side of the toolbar frame. The first wing may be coupled to the elevator and pivotable about a first vertical axis of rotation between an extended and a folded position. Tools may be coupled to the first wing and rotatable relative to a longitudinal axis of the first wing from an operating position below the first wing to a transport/shipping position above the first wing. Further, the first wing may be adapted to be moveable to position the first wing higher than a wheel of the agricultural implement on the same side of the toolbar frame in the folded position. Subsequently, the tools may be circularly rotated and the middle wing and tools pushed down to reduce the overall width and height of the implement for transporting or shipping.

A mower apparatus has a tool bar mounted on wheels has a center section and right and left wing sections pivotally attached to the center section. When the tool bar is in an operating position the wing sections extend laterally from the center section perpendicular to the operating travel direction, and in a transport position the wing sections extend rearward or forward from the center section. A plurality of mowing units is attached to the tool bar such that when the tool bar is in the operating position each mowing unit extends rearward from the tool bar, and when the tool bar is in the transport position each mowing unit extends upward from the tool bar.

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

An agricultural implement has a hitch frame, a center frame pivotally attached rearward of the hitch frame about a hitch pivot axis. Wing frames are pivotally attached to ends of the center frame and a center actuator is pivots the center and wing frames from a rearward extending operating position to an upward extending transport position. Caster wheels are pivotally mounted on front sides of the wing frames about caster and transport axes. In the operating position, the caster axes are oriented vertically and the transport axes are oriented horizontally, and in the initial transport position, the caster axes are oriented horizontally, perpendicular to the hitch pivot, the transport axes are oriented vertically, and caster wheel actuators pivot the caster wheels 90 degrees about the transport axes to align the caster axes with the hitch pivot axis. The caster wheels support the wing frames in both operating and transport positions.
