A seed planter assembly for planting seeds in rows throughout a field includes at least one tank for storing the seeds and a seed hose in communication with the at least one tank for delivering the seeds to the field. The seed planter assembly also includes a support frame for supporting the at least one tank and the seed hose, and a linkage assembly (e.g., including a four-bar linkage) coupled with the support frame and the at least one tank. The linkage assembly is configured for lifting the at least one tank from a first orientation proximate to a support surface to a second orientation spaced farther apart from the support surface. The seed planter assembly can also include an actuator (e.g., a hydraulic actuator) connected between the support frame and the linkage assembly for moving the at least one tank between the first orientation and the second orientation.

A product distribution system mounting assembly includes a first member configured to rigidly couple to a frame of an agricultural apparatus and a second member configured to rigidly couple to a plurality of tubular components of a product distribution system of the agricultural apparatus. The first member and the second member are configured to engage with one another to form a sliding interface that enables the plurality of tubular components to move along a vertical axis relative to the frame as the agricultural apparatus moves in a direction of travel through a field.

A control system for managing weight transfer along sections of a tractor drawn tool bar for use in row planting systems is provided. The planter weight transfer system comprises first and second assemblies secured to each other and to a row planter tool bar by a set of fasteners. Additionally, the bolt-on brackets are joined at the top by an actuator which applies a force on the brackets. An improved PID-based WTS control system provides improved and balanced operation of agricultural machinery planting multiple rows with a multiple row planter units attached along a set of tool bars, wherein the wing sections and the center section of the tool bar complex are maintained in relative position by operation of the WTS and control system.

In one embodiment, an in-line tandem axle assembly comprising: a tandem wheel arm; a pair of wheel connecting assemblies, each comprising a hub and a spindle; a pair of mounts coupled respectively to the pair of wheel connecting assemblies; a pair of wheels 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 of equal length pivotably mounted to the pair of mounts and pivotably mounted to the tandem wheel arm.

An agricultural vehicle includes a coupling structure for making a tool-less attachment between a first connector piece and a second connector piece. The first connector piece has at least one pin, and the second connector piece has at least one slot adapted to receive the pin in a receiving pocket that is circumferentially spaced from an axially-open inlet portion of the slot. The slot includes an inlet ramp between the slot inlet portion and the receiving pocket, and the inlet ramp is less steeply angled than a second ramp surface that forms a portion of the receiving pocket adjacent the first ramp.

Planting apparatus includes: (i) a housing that defines: a primary guide; and first and second opposed branch guides extending laterally from the primary guide; (ii) a first runner slidably secured to, and movable along the primary guide; (iii) a second runner securable to, and movable along a first branch guide; and (iv) a third runner securable to, and movable along a second branch guide. The first, second and third runners are configured such that: the second runner is receivable from the first branch guide on to the first runner; and the third runner is receivable from the second branch guide on to the first runner. Drive means move: (i) the second runner along the first branch guide and on to the first runner; (ii) the third runner along the second branch guide and on to the first runner; and (iii) the first runner, together with either of the second or third runners received thereon, along the primary guide.

Described herein are technologies for mapping sensed positions of a toolbar of an agricultural implement, such as when the implement moves through a crop field. The technologies include a method including (1) sensing a position of the toolbar at a geographic location of the field, (2) matching the location of the field with a position in a map of the field corresponding to the location, and (3) associating the sensed position of the toolbar to the position in the map. In some embodiments, the method includes repeating the aforesaid operations for multiple geographic locations of the field and rendering an image of the map to be displayed in a GUI. Also, in some embodiments, the method includes rendering the image of the map with an image of a yield map of the field. In some embodiments, the method includes generating a topographic map based on the sensed toolbar positions.

A bulk seed cart has a dual conveyor system adjustable about three axes to provide easy alignment of the conveyor discharge chute over a planter seed tank fill opening. The conveyor assembly is adjustable about a vertical axis between field and transport positions, about a first horizontal axis for laterally extending and retracting the discharge chute, and about a second horizontal axis for raising and lowering the discharge chute. The inner and outer conveyors of the conveyor assembly are linked to move in unison in a lateral direction about a first horizontal pivot axis. The outer conveyer is pivotal about the second horizontal axis and the vertical axis.

A work vehicle includes a frame and a row unit that is attached to the frame. The row unit includes a gauge wheel and a ground engaging implement. The gauge wheel is configured to ride on the ground surface and maintain the ground engaging implement at a predetermined vertical position with respect to the ground surface. Furthermore, the work vehicle includes a ground support unit that supports the frame for movement across the ground surface. The ground support unit includes an outer face. The outer face includes a non-treaded side area that defines a lateral side of the outer face. The outer face includes a tread area that is spaced laterally from the lateral edge. The tread area includes a plurality of projections. The non-treaded side area is aligned along the travel direction with respect to the gauge wheel.

An agricultural machine includes a main frame, a rotate frame, and a row unit. A control method for the machine includes: selecting at least one of: (i) a desired position-based relationship between a portion of the rotate frame and the row unit, and (ii) a desired downforce of the row unit; determining at least one of: (i) an actual position-based relationship defined between the rearward portion of the rotate frame and the row unit, and (ii) an actual downforce of the row unit; and adjusting at least one of: (i) the actual position-based relationship toward the desired position-based relationship, and (ii) the actual downforce of the row unit toward the desired downforce of the row unit; wherein adjusting the actual position-based relationship and adjusting the actual downforce of the row both include moving the rotate frame relative to the main frame of the agricultural machine.
