An agricultural machine includes a main frame, an adjustable frame coupled to the main frame and, a row unit which includes a linking arm coupled to the adjustable frame, and an actuator coupled to the main frame and the adjustable frame. The agricultural machine also includes a controller configured to command the actuator to move to various positions based on signals received from one or more sensors. The one or more sensors are configured to measure one more indicators associated with an actual height of the row unit relative to ground.

An agricultural machine includes a main frame, an adjustable frame coupled to the main frame and, a row unit which includes a linking arm coupled to the adjustable frame, and an actuator coupled to the main frame and the adjustable frame. The agricultural machine also includes a controller configured to command the actuator to output various downforces to the row units based on signals received from one or more sensors. The one or more sensors are configured to measure one more indicators associated with an actual height of the row unit relative to ground.

An agricultural toolbar has a center section and opposite wings which are horizontally foldable between transport and field positions. The toolbar has a hydraulic system which is very adaptable to many different hydraulically controlled features and options, without sacrificing the primary purpose of the system, which is accurately controlling the operating height of the toolbar, to achieve optimal planting depth of modern precision seed and fertilizer application systems.

An agricultural planting implement includes a first wing toolbar configured to support a first set of row units and a second wing toolbar configured to support a second set of row units. The agricultural planting implement also includes a connection assembly having at least one arm pivotally coupling the second wing toolbar to the first wing toolbar. The at least one arm is pivotally coupled to the first wing toolbar and non-pivotally coupled to the second wing toolbar. In addition, the connection assembly includes an actuator configured to drive the second wing toolbar to rotate upwardly relative to the first wing toolbar from a working position to a transport position. The actuator is also configured to urge the second wing toolbar downwardly toward a soil surface while the second wing toolbar is in the working position.

In one embodiment, an in-line tandem axle assembly comprising: a tandem wheel arm (46); a pair of wheel connecting assemblies (44A, 44B), each comprising a hub (60A, 60B) and a spindle (58A, 58B); a pair of mounts (50A, 50B) coupled respectively to the pair of wheel connecting assemblies; a pair of wheels (52A, 52B) coupled respectively to the pair of wheel connecting assemblies, the pair of wheels separated by the tandem wheel arm and in a same fore-and-aft position; and plural pairs of parallel links (48A, 48B) of equal length pivotably mounted to the pair of mounts and pivotably mounted to the tandem wheel arm.

An agricultural implement includes a toolbar that extends transverse to a tongue when in a field use configuration. The toolbar can be lifted and/or rotated relative to the tongue to transition between a field use and a transport use. A lifting assembly includes one or more actuators and linkage systems to lift the toolbar attached thereto in an arced manner in moving from a field use configuration to a transport configuration. A rotating mechanism can also include one or more actuators to rotate the toolbar about a pivot member. An anti-rotation link includes a member is connected to the toolbar and can be positioned at least partially within a groove to mitigate rotation of the toolbar, such as during the lifting of the toolbar.

An agricultural distribution device for spreading granular material to be distributed such as seed, fertilizer or the like is disclosed. The distribution device has a frame with at least one storage container for material to be distributed mounted thereon and a tool bar having a toolbar center section and toolbar wings pivotally mounted on opposite ends thereof and a plurality of row units mounted on the tool bar center section and each of the toolbar wings. The toolbar wings are pivotable between working and transport positions. In the working position the toolbar wings extend generally in longitudinal alignment with the center section. In the transport position the toolbar wings are pivoted about a pivoting angle of more than 90° and up to 180° with at least a portion of each toolbar wing or any row units attached thereto supported above the at least one storage container.

Systems, devices, and methods for performing autonomous agricultural operations are described herein. An exemplary device may include a toolbar to which a plurality of implements may be interchangeably coupled, and a pair of parallel chassis beams mounted perpendicularly on the toolbar. At least a portion of each of the chassis beams may be telescopic and configured to be extended outward from, and retracted inward towards, the toolbar. The device may also include a plurality of drive assemblies each mounted on one of the chassis beams, and a plurality of motors corresponding to the drive assemblies and configured to drive the drive assemblies in accordance with one or more drive parameters to move the device throughout a site. The device may further include a computing device configured to automatically determine the drive parameters, and cause the plurality of motors to drive the corresponding drive assemblies in accordance with the drive parameters.
