An agricultural harvester including a feeder. The feeder is pivotally mounted to an intermediate frame with respect to a first axis of motion. The intermediate frame is pivotally mounted to a header mounting frame with respect to a second axis of motion. Pivoting around the first axis of motion and the second axis of motion allows a fore-aft movement and a lateral tilt movement. At least one lateral tilt actuator is provided to actuate the header mounting frame in the lateral tilt movement. At least two fore-aft actuators are provided for extending between a first set of mounting positions at the feeder and a second set of mounting positions at the header mounting frame to actuate the header mounting frame in the fore-aft movement.

A device for automatically adjusting the working width of the first plough body of a plough in accordance with the variable working width of subsequent plough bodies. A first hydraulic cylinder displaces a rear frame section laterally. A second hydraulic cylinder pivots the rear frame section to adjust a transverse spacing of the plough bodies. The first hydraulic cylinder includes a multi-stage cylinder. A first cylinder stage forms a main lateral control, and a second cylinder stage forms an automatic working-width control for the first plough body. The second cylinder stage is in hydraulic-fluid communication with the second hydraulic cylinder in a master-slave configuration. The second cylinder stage is master or the slave depending on a moving direction of the cylinder stage and the second hydraulic cylinder being slave or the master. Piston diameters are matched to provide a correction of a lateral displacement of the front frame section.

Representative implementations of devices and techniques provide a tool bar comprising a structure having a plurality of sections arranged in geometric forms. The geometric forms may change shape to keep a tool that is attached to the structure in a desired position while the tool bar is being used on uneven terrain, such as on a hillside or while the tool bar is rotated or pivoted at an angle with respect to the direction of travel. Changing the shape of the geometric forms can also result in rotating the tool attached to the structure with respect to the tool bar.

A tractor includes a frame defines longitudinal (nominally forward and backward), lateral (nominally left and right), and transverse (nominally up and down) directions (mutually orthogonal). First and second side structures connect by a width adjustment structure comprising beams of bearing length and bearing width capable of supporting loads (torque, bending, etc.) at any of a plurality of widths therebetween. Individual drive systems in the first and second sides each include a track, motor, sprocket, main idler, and bogey idlers. A carrier system secures, lifts, and descends an implement. Implements may be of any type, such as tillage, harrowing, furrowing, seeding, cultivation, personnel carrier, or the like. A controller is capable of directing the tractor based on a pre-determined course of travel, or a guided course in response to physical features in a farming field.

Apparatus and associated methods for a coulter disk system relate to a lateral actuator module having a programmably positionable control member that is coupled to a gang of coulter disks and is operable to position a control point of the coulter disks at a predetermined position between two opposing, laterally-spaced end-of-travel positions. In an exemplary embodiment, a gang may be mechanically connected to and laterally positioned by the control point. The predetermined position may be, in some examples, dynamically calculated according to a predetermined function and based on information about conditions of the soil in contact with the coulter disks. Various embodiments may dynamically adjust the position of a gang of coulter disks to dynamically and automatically optimize the conditioning effectiveness of the gang of coulter disks in response to parametric information about the soil conditions.

A harvesting header includes a header frame structured to be coupled to the crop-harvesting machine, a hydraulic pump carried by the header frame, at least one tool carried by the header frame, a hydraulic fluid loop carried by the header frame, a fluid inlet structured to receive hydraulic fluid from the crop-harvesting machine, and a fluid outlet structured to deliver hydraulic fluid to the crop-harvesting machine. The hydraulic fluid loop is structured to circulate hydraulic fluid within the header from the hydraulic pump to the tool(s) and back to the hydraulic pump. Related methods of operating a harvesting header and a non-transitory computer-readable media are also disclosed.

The adjustable hitch assembly of the present invention is mounted to the 3 point hitch system or quick attach frame on the rear of a tractor, and allows equipment, tools and implements to be hitched thereto. The hitch assembly includes a frame for mounting to the tractor, a carriage slidably mounted to the frame, and a hitch plate extending rearwardly from the carriage. The hitch assembly also includes an actuator for adjusting the lateral position of the hitch plate relative to the tractor. The actuator is coupled to the hydraulic system of the tractor. The actuator can be controlled remotely from the cab of the tractor.

A wheel assembly for a multi-row planter comprises a wheel, a connection assembly, and a piston assembly. The connection assembly has a mounting surface adapted to engage a mounting bracket for mounting to a planter bar. The a piston assembly is adapted to permit movement of the wheel assembly between a first folded position and a second extended position. The wheel assembly is slidably coupled to the planter bar such that it may be slidably positioned at any point along the full lateral length of the planter bar.

A tillage implement includes a front gang and a rear gang. The front gang includes a first row of spoke wheels, each coupled to a front axle at an oblique angle. The rear gang includes a second row of spoke wheels, each coupled to a rear axle at the oblique angle. The tillage implement also includes a row of disc blades positioned behind the front gang and the rear gang with respect to a direction of travel of the tillage implement.

One or more techniques and/or systems are disclosed for mounting a dual fertilizer opener to a planting implement, the dual fertilizer opener including a frame support having a first end and a second end, the first end mounted to a frame of a planting implement and positioned such that the dual fertilizer opener is implemented before a seed opener, and the second end coupled to a first opener assembly and a second opener assembly. Each opener assembly is configured to individually pivot about the second end of the frame support, a downforce being exerted on each by a spring. Each opener assembly is further configured to be adjustable such that each trench opened in the soil may be at a desired depth and distance from a seed location, resulting in greater root development that increases nutrient taking and yield
