A land roller is provided the can be transformed between a transport position and an operating position by at least one actuator. 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.

An end wheel assembly for transforming an implement frame from a transport position to a field position is provided. The end wheel assembly can have an end wheel, a wheel pivot rotatably connected to the end wheel, a wheel member pivotally connected to the wheel pivot, at least one attachment bracket attached to the wheel member and pivotally attachable to the implement frame, a wheel actuator to raise and lower the end wheel assembly, and a guide plate. The guide plate can have a channel, a first end connected to the wheel member, and a second end connected to the wheel pivot. The channel can be positioned to receive a positioning member when the end wheel assembly is pivoted downwards and to rotate the guide plate causing the wheel pivot and end wheel to rotate relative to the wheel member and turn the end wheel outwards.

An agricultural vehicle-trailer combination includes a traction module including a drive element for engaging in a ground, a working appliance coupled to the traction module by a coupling apparatus, and a folding axle supporting the working appliance relative to the ground at least during a transport mode. A slewing mechanism of the coupling apparatus provides a degree of freedom of rotation between the traction module and the working appliance along a longitudinal axis of the working appliance. A pivot joint provides a degree of freedom of pivoting between the traction module and the working appliance along a vertical axis of the traction module. The pivot joint is adjustable relative to its pivot angle by a steering actuator for influencing the direction of travel of the vehicle-trailer combination.

A land roller implement includes a main frame section, two intermediate frame sections extending laterally outward from opposing sides of the main frame section in a trailing relationship therewith in a working position, and a pair of outer frame sections extending laterally outward from respective intermediate frame sections in a leading relationship therewith in the working position. The outer frame sections are coupled to the intermediate frame sections by readily removable outer brace portions to reduce the transport width if required. Inner brace members are coupled between the main frame section and the intermediate frame sections by coupling to the outer brace portions at the outer ends and by pivoting on the main frame section about a floating axis which is coaxial with floating movement of the intermediate frame sections relative to the main frame section.

A grading implement features a frame with at least one movable section carried by a main frame section. Each movable section is movable relative thereto between a storage position and a working position reaching further laterally outward from the main section to increase a working width of the implement. An underside of each movable section features a respective blade adjustably mounted thereto for selective adjustment between different relative blade positions relative to the movable section. One embodiment features outboard blades on two movable sections, inboard blades on another two movable sections, and a rear blade mounted centrally on the main section behind the inboard and outboard blades. A dust suppression system features spray nozzles distributed across the main frame section behind the blades, and storage tanks mounted atop the main section so that weight of the dust suppression agent provides extra downforce to the blades.

A land roller is provided with an over-center locking linkage arrangement to help lock a roller frame of the land roller into a raised transport configuration to reduce the likelihood that a failure of the actuator system could cause the roller frame to inadvertently fall and injure a person or cause damage to property. The land roller may be further provided with actuators that are controlled in temporal series from a single controller to simplify and increase the safety of both converting the land roller between the transport configuration and a working configuration and converting side frame sections of the land roller between folded and unfolded positions.
