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.

An agricultural implement system includes a tow bar configured to couple to a hitch assembly. The agricultural implement system also includes a tool bar pivot hinge assembly comprising two pivot points. The agricultural implement system additionally includes a first tool bar member mechanically coupled to a second tool bar member via the tool bar pivot hinge assembly; the first tool bar member extending transversely from the tow bar, wherein the tool bar pivot hinge assembly provides for an axis of rotation of the second tool bar member about the first tool bar member and additionally provides for an extension of the second tool bar member away from the first tool bar member.

A hinge assembly for an agricultural implement having inner and outer wing frame sections has an inner pivot bracket pivotally coupled to the inner wing frame section at a fold pivot location, and an outer pivot bracket pivotally coupled to the outer wing frame section at a flex pivot location and coupled to the inner pivot bracket. An inner pivot link pivotally couples to the inner pivot bracket and the outer pivot bracket, and an outer pivot link pivotally couples to the outer pivot bracket and the outer wing frame section. The inner and outer pivot brackets pivot relative to each other at the fold pivot location between a working state and a folded state, and the flex pivot location moves relative to the fold pivot location during the relative pivoting. When in the working state, the fold pivot location is higher than a top side of the inner wing frame section and the flex pivot location is lower than a bottom side of the inner wing frame section.

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.

A tool bar system is provided that is configured and arranged with weight distribution that inhibits the tool bar system from applying lifting forces to the rear hitch of the tractor that is pulling the tool bar. In one or more embodiments, the toolbar system includes a frame, lift wheels, a tool mount bar assembly having one or more forward sections and one or more rearward sections. The rearward sections are positioned rearward of lift wheels. Forward sections are positioned closer to the front of the tool bar system than the rearward sections, thereby reducing lifting forces at the front end of the tool bar system.

A tillage implement has a frame with a center section and first and second outer wing sections hingedly attached the center section such that the wing sections can be operably raised and lowered between a field-working position and a transport position. The sections each carry tillage tools for working the soil. Controlling a precharge in a secondary side of a hydraulic circuit enables the operator of the implement to adjust the downward pressure precharge provided by a plurality of hydraulic cylinders based on a desired stiffness of the implement. A pressure-reducing valve is configured such that flow from the hydraulic supply applies downward pressure precharge on the plurality of tillage tools. Once this desired precharge has been achieved, flow from the hydraulic supply is shut off and a check valve holds the pressure such that the plurality of hydraulic cylinders holds the tillage tools in position.

An agricultural vehicle header having a base structure, a header wing section, an articulated joint connecting the header wing section to the base structure, an actuator, a load sensor, and a controller. The actuator is configured to move the header wing section relative to the base structure between a wing lowered position and a wing raised position the load sensor is operatively connected to the header wing section. The controller is configured to acquire load sensor data from the load sensor to evaluate a magnitude of a gravitational load on the header wing section, and prevent the actuator from moving the header wing section towards the wing raised position if the magnitude of the gravitational load exceeds a predetermined threshold load value. An agricultural combine having the header and methods of operating the same are also provided.

The present application relates to a soil tillage implement (10) having soil tillage tools (28), in particular disc tools, which are arranged in multiple tool rows (30.1 . . . 30.3) following one another in the working direction (A) and which are oriented transversely to the working direction (A), and having a running gear with at least one main wheel (20.1, 20.2), which is spaced apart from a centre longitudinal axis (22) transversely to the working direction (A) by a lateral wheel distance (dr). Here, the running gear is arranged with respect to the soil tillage tools (28) in such a manner that with respect to the working direction (A) in front of and to the left and right of the running gear at least one soil tillage tool (28) is arranged. All soil tillage tools (28) which are arranged in the tool row (30.1) located furthest in front of the running gear in the working direction (A) have a lateral tool distance (dw) from the centre longitudinal axis (28) that is smaller than or equal to the lateral wheel distance (dr).

An agricultural implement includes a longitudinally extending frame configured to be coupled to a tractor, a first elongate toolbar extending laterally outward from the frame and carrying a first row unit, a second elongate toolbar extending laterally outward the frame and carrying a second row unit, a first sensor configured to sense a position of the first row unit relative to ground, a second sensor configured to sense a position of the second row unit relative to the ground, a first actuator configured to rotate the first elongate toolbar relative to the frame based at least in part on the sensed position of the first row unit, and an actuator configured to rotate the second elongate toolbar relative to the frame based at least in part on the sensed position of the second row unit. Control systems and related methods are also disclosed.

An agricultural tool bar has outer wings foldable between a lowered use or field position and a raised transport position. A primary pair of hydraulic cylinders fold and unfold the wings, while a secondary pair of hydraulic cylinders initially incline the wings from the horizontal use position before folding to the transport position. The secondary set of cylinders allow the tool bar to be used for narrow row planting without interference from seed boxes mounted on the toolbar center frame and the wings. The primary cylinders extend to push the wings to the transport position and retract to pull the wings to the use position.
