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.

A seed selector assembly for a pneumatic meter employed in agricultural seeding equipment may include a seed selector assembly connected to a multi-functional coupler, in which the seed selector assembly is made up of a rotating disk with a central hole and a gear profile, the disk being enclosed by a front ring and a rear ring, and the multi-functional coupler having two interfaces for connecting motor or driven devices. A pinion may be connected to an end of an axis, the opposite end of which is connected to a crown, the pinion being fitted into the cavity of the rear ring and the circular bore of the front ring, with a housed bearing support. The pinion may interact with the gear profile in order to rotate the disk when at least one of the interfaces is connected to a motor device.

A row unit for a seeding machine includes a frame and a seed meter coupled to the frame. The seed meter has a metering member for singulating seeds. The metering member has a groove recessed from a surface of the metering member. The row unit also includes a ramp surface for guiding the singulated seeds from the metering member, the ramp surface being at least partially disposed in the groove.

An agricultural sowing implement that, when moved by a drive unit, distributes seeds in the ground with regular, uniform spacing. The agricultural sowing implement comprises a rocker system placed behind the chassis of the implement where a seed dispenser is positioned. The rocker system may include a beam connected to two depth-limiting wheels on the ends of the beam. In one embodiment of the disclosure, provision is made for two interlinked smaller wheels connected to a central lower extension of the beam, the set of wheels being encircled by a rolling band. In addition, provision is made for two dampers, one for each of the depth-limiting wheels.

A row unit of an agricultural planter includes a seed meter. The seed meter includes a seed disk within a seed meter housing. The seed disk is positioned in the seed meter housing such that the disk rotates and includes a seed release point. A drive member is operatively connected to the seed disk such that the drive member selectively rotates the disk. The seed disk is angularly positioned and is a conical-shaped member with a central axis and includes seed cells radially positioned about an outer portion. The seed disk is substantially non-perpendicular to the central axis. An air pressure source also is included to adhere seed to the disk.

An adjustment mechanism is provided for a multi-row seed planter to provide infinite adjustability of the seed discs to allow precision planting with staggered seed rows. The adjustment mechanism comprises an idler roller on the end of a pivotal arm about which the drive chain is trained. The position of the roller can be adjusted to modify the chain path, and thereby rotate the seed metering sprocket and associated seed disc to a desired angular position before planting begins.

A sowing heart control apparatus for controlling a sowing heart with a sowing heart monitoring apparatus having an evaluation unit for determining the occupancy of sowing holes of a rotating seed disk with a seed in operation. The evaluation unit delivers an actual value of the occupancy of one or more sowing holes. The sowing heart control apparatus, depending on a deviation of the actual occupancy value from a predetermined setpoint of the occupancy of one or more sowing holes, controlling actuating elements which influence the occupancy. The invention also relates to a sowing heart and a single seed drill.
