An agricultural tillage implement including a main frame section having a pull hitch tube extending in a travel direction and a plurality of pivotally coupled wing sections coupled with the main frame section. Each of the plurality of wing sections has at least one pivotal sub-frame. A hydraulic actuator is connected between the wing frame and the sub-frame to urge the sub-frame between an operating position and an elevated transport position. An actuator controller is configured to apply a predetermined force of the sub-frame towards the ground independently of other sub-frames so as to provide a more uniform tillage of the ground.

A cultivator is provided for cultivating a field. The cultivator can have a frame with a tow assembly so that the cultivator can be towed by a tractor. A cultivating assembly can be provided pivotally attached to the rear of the frame. The cultivating assembly can have a plurality of discs that engage and penetrate the soil beneath the cultivating assembly. The cultivating assembly can have a center section pivotally connected at the to the rear end of the frame, a first wing section pivotally connected to one side of the center section, a second wing pivotally connected the other side of center section where all the sections have discs connected to them. A pair of ground wheels can be provided connected to the center section so that the ground wheels are positioned in front of the cultivating assembly when it is being used to cultivate a field.

An agricultural implement system including a hitch assembly configured to couple to a tow vehicle, a plurality of wing tool bars coupled transversely to the hitch assembly, and a plurality of wing frames pivotally coupled to the plurality of wing tool bars. Each wing frame is configured to support a plurality of row units and is positioned forward of a respective wing tool bar. The agricultural implement system further includes an air cart support arm with a first and second end. The first end of the air cart support arm is pivotally coupled to the wing tool bar and the second end of the air cart support arm is configured to couple to an air cart and the air cart support arm is configured to drive the air cart in a rearward direction relative to the hitch assembly in response to rotation of the wing tool bar in the rearward direction.

An agricultural tillage implement includes a main section including a hitch extending in a travel direction, a plurality of foldable wing sections coupled with the main section, at least one auxiliary implement assembly coupled to each of the wing sections and a control system. Each auxiliary implement assembly includes at least one support member, at least one pivotal arm pivotally coupled to the support member, at least one actuator coupled to both the support member and the pivotal arm and a ground contacting implement coupled to the pivotal arm. The control system is configured to actuate the actuators to control a position of each ground contacting implement in each of the sections when the agricultural implement is transitioning to a transport mode.

An agricultural implement has a center frame supported on center wheels and right and left interframes are pivotally attached to corresponding ends of the center frame about wing pivot axes. Right and left wing frames are pivotally attached at front inner ends thereof to front ends of corresponding interframes about front interframe pivot axes. Rear inner portions of the wing frames are movably attached to corresponding interframes. Latch mechanisms selectively lock the rear inner portions each wing frame to rear portions of the corresponding interframes. A center actuator pivots the center frame such that the frames move from an operating position extending rearward to an initial transport position extending upward where the interframes and wing frames can pivot rearward about the upright wing pivot axes. The front interframe pivot axes are oriented perpendicular to the wing pivot axes.

A cultivator can have a frame with a tow assembly so that the cultivator can be towed by a tractor. A cultivating assembly can be pivotally attached to the rear of the frame. The cultivating assembly can have a plurality of discs that engage and penetrate the soil beneath the cultivating assembly. The cultivating assembly can have a center section pivotally connected to the rear end of the frame, a first wing section pivotally connected to one side of the center section, a second wing pivotally connected to the other side of center section where all the sections have discs connected to them. A pair of ground wheels can be connected to the center section so that the ground wheels are positioned in front of the cultivating assembly when it is being used to cultivate a field.

The invention relates to an agricultural machine that has two sections hinged relative to each other, at least one oblong hole being made in one of the two sections, the machine including a connecting device that has an actuator configured to cause one section to pivot relative to the other, and a travel stop, the actuator supporting a movable pivot rod, with a longitudinal axis transverse to the oblong hole, the movable pivot rod being positioned to slide in the length of the oblong hole, the travel stop having a blocking state in which it obstructs the oblong hole, thereby limiting the sliding of the pivot rod in the oblong hole, the travel stop being able to achieve the blocking state from a free state in which it is mounted in a movable rotating manner relative to the oblong hole.

A latching arrangement for an agricultural implement having components which may be retracted or folded from an extended operational position to a stowed position better suited to transport and/or storage including a first remotely operable actuating mechanism for moving a component between the stowed and extended positions, a lever having a component engaging hook near one end and a fulcrum fixed to the implement, and a second remotely operable actuating mechanism for selectively engaging the hook and component only when the component is in the stowed position. The second actuating mechanism is operable independently of, and from the same location as, the first actuating mechanism. The second actuating mechanism comprises a hydraulic cylinder fixed to the implement and having a piston rod coupled to the lever near a lever end opposite the hook.
