An autonomous tractor for autonomously crossing farmland, includes one or more sensors for detection of an obstacle when crossing the farmland, and a central processing unit (CPU) for receiving input signals from the the sensors and for controlling movement of the tractor based on the input signals in order to avoid the obstacle, a coupler for coupling an agricultural machine able to be coupled to the tractor, and the agricultural machine includes one or more additional sensors for detection of the obstacle, wherein coupling of the agricultural machine operatively connects the additional sensors to the CPU and automatically provides data to the CPU regarding the location of each of the additional sensors on the agricultural machine and one or more specifications of each of these additional sensors.

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.

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.

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 constructive arrangement applied to a grain harvesting machine reducing the sizes of the bulk carrier and the collecting set, bringing them to measurements which are compatible with the body of the machine, thus enabling transportation next to the machine, with no need to disassemble any parts, having hinges and support arms of the bucket and the support structure of the receiving device provided with hinging devices to reduce their lateral dimensions, those hinging devices being activated by hydraulic cylinders.

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.

A towed agricultural implement including a main chassis member, a moveable arm for carrying at least one working implement located to each side of the main chassis member, each moveable arm being moveable between a working position and a transport position, the main chassis member having a support device for attachment to a towing vehicle, the support device having left and right lower attachment points for attaching to lower mounting points of a three point hitch of a towing vehicle and a central upper attachment point for attaching to the upper mounting point of the three point hitch, in which each left and right attachment point is mounted on an articulated arm connected to the main chassis member, the main chassis member further including a regulating control apparatus to secure and release a free end of each articulated arm in an operative position. This construction has as an advantage that on encountering an obstacle the articulated arm can be released allowing the working implement to move away from the obstacle.

An agricultural implement for cultivating an agricultural work area includes a main frame which is transferable between an operating position and a transfer position. A first subframe is connected to the main frame, and the first subframe is transferable between an operating position and a transfer position. A main frame hydraulic cylinder and a first subframe hydraulic cylinder move the main frame and the first subframe between their corresponding positions. In order to provide correct and repeatable positioning of the first subframe hydraulic cylinder, a volume of a first chamber of the main frame hydraulic cylinder is substantially equal to a volume of the first chamber of the first subframe hydraulic cylinder when the first subframe is in its operating position.
