An agricultural implement including a central chassis member having a support structure with support arms connected to the support structure for movement between a working position and a transport position, the support arms having operating elements defining a working width between the operating elements and the main chassis member. The support arms are adjustable in the working position between a length corresponding to minimum working width and a length greater than the minimum working width. In the transport position a distance between the operating elements and the main chassis member is less than the minimum working width. A first stop defines the position of the minimum working width and a second stop arranged vertically with respect to the first stop retains the support arm in the transport position when the distance between the operating elements and the main chassis member is less than the minimum working width.

An apparatus, which may be a tillage apparatus, has a flexible frame. The frame may be made from open members. The frame may support ground engagers and may be supported on wheel assemblies. The ground engagers may be connected to a spring trip mechanism. The ground engagers may be mounted to open members of the frame with a clamping style mechanism. The clamp mechanism may include wedge devices. The frame may be lowered and raised relative to wheels of the wheel assemblies with a lift mechanism. One row of ground engagers may be raised or lowered relative to the frame independent of another row of ground engagers. An anti-skid or skew control system may be employed in association with the independent height adjustment of one row of ground engagers. A system may be provided to maintain and control the height of a tow hitch forming part of the apparatus.

An agricultural implement includes a transversely extending frame forming at least a first frame section, a second frame section, and a third frame section, where the first frame section is disposed between the second and third frame sections. A pair of elongated gang assemblies are on the first frame section, an elongated gang assembly is on the second frame section, and an elongated gang assembly is on the third frame section. Each of the gang assemblies is horizontally adjustable relative to the frame. An actuator for each gang assembly operably controls the angular adjustment of the gang assemblies, and a fluid source supplies fluid to the actuators. The actuator on the second frame section is a master actuator for one of the actuators on the first frame section, and the actuator on the third frame section is a master actuator for the other actuator on the first frame section.

A horizontally foldable toolbar includes opposite wings having flex joints which can be selectively locked to prevent flexing of the joints when the wings are in a transport position and unlocked to permit flexing of the joints when the wings are in a field position. The lock assembly includes a hydraulic cylinder with an extendable and retractable arm. Operation of the hydraulic cylinder can be controlled by an operator remotely, such as from a tractor cab. The stroke of the hydraulic cylinder can be adjusted to accommodate wear on the wing components.

An agricultural implement includes a frame supporting a plurality of ground-engaging tools and a foldable marker assembly having a first marker arm coupled to the frame at a first pivot joint. The first marker arm is operable to pivot between an extended position extending laterally outward from the frame and a folded position at an acute angle relative to the frame.

A mower includes a frame, at least one cutting unit, and a lifting unit. The lifting unit is connected to the at least one cutting unit and includes a yoke assembly, a first arm assembly, a second arm assembly, and a third arm assembly. The yoke assembly is connected to the cutting unit. The first arm assembly is pivotably mounted to the vehicle frame about a first pivot axis. The second arm assembly is pivotably mounted to the first arm assembly about a second pivot axis and to the yoke assembly about a third pivot axis with the second pivot axis and third pivot axis being non-parallel to the first pivot axis. The third arm assembly includes a first end pivotally connected to the frame and a second end pivotally connected to the second arm assembly.

Systems, methods, and apparatus for shifting weight between a tractor and toolbar and between sections of the toolbar and for folding a toolbar between a field position and a transport position.

A carrier adjustment assembly for coupling to a frame member of an implement includes a laterally adjustable carrier configured to be coupled to an opener and a first outlet providing at least one nutrient. The assembly further includes a plurality of lateral spacers positioned adjacent to the carrier to laterally adjust the carrier and provide a plurality of adjustment positions. The carrier adjustment assembly facilitates lateral adjustment of the carrier by removal of at least one captively held lateral spacer that sets the lateral adjustment of the carrier, a lateral adjustment of the first outlet, and an adjustment of a lateral separation between a seed row provided by a second outlet and a nutrient row provided by the first outlet.

An articulated nozzle-holder boom arm for agricultural sprayer which is extensible to the sides of a main chassis and which can be folded to a transportation position by means of an intermediate hinge generally placed in an intermediate point of the boom arm, and the several sections of the beam forming the boom arm can be engaged or disengaged easily and without welding in the hinge or several supports of the beam sections, being the beam sections generally extruded aluminum profiles and the union of the profiles ends obtained engaging the same in retaining flanges included in the supports and hinges of connection of the sections.

A corn head corn head includes a first wing segment and a center segment. A corn head adjustment system includes a first fold actuator; a first deck plate actuator mounted on at least one of the first wing segment frame or the center frame and configured to reposition at least one of the first deck plate rod or the center deck plate rod; and corn head hydraulics. During a fold process, the corn head hydraulics is configured to actuate the first fold actuator in order to fold the first wing segment relative to the center segment and to actuate the first deck plate actuator in order to decouple the first deck plate rod from the center deck plate rod. During an unfold process, the corn head hydraulics is configured to actuate the first fold actuator in order to unfold the first wing segment relative to the center segment.
